_MARSUPIALS AND MONOTREMES._

MARSUPIALS.

With the order of the Pouched Mammals we arrive--with the exception of the Echidna and Platypus, next described--at the most simply organised representatives of the Mammalian Class. In the two forms above named, egg-production, after the manner of birds and reptiles, constitutes the only method of propagation. Although among marsupials so rudimentary a method of reproduction is not met with, the young are brought into the world in a far more embryonic condition than occurs among any of the mammalian groups previously enumerated. There is, as a matter of fact, an entire absence of that vascular or blood connection betwixt the parent and young previous to birth, known as placentation, common to all the higher mammals, though certain of the more generalised forms have been recently found to possess a rudiment of such development. In correlation with their abnormally premature birth, it may be observed that a special provision commonly exists for the early nurture of the infant marsupials. In such a form as the Kangaroo, for example, the young one is placed, through the instrumentality of its parent's lips, in contact with the food-supplying teat, and to which for some considerable period it then becomes inseparably attached. Special muscles exist in connection with the parent's mammary glands for controlling the supply of milk to the young animal, while the respiratory organs of the little creature are temporarily modified in order to ensure unimpeded respiration. The fact of the young in their early life being commonly found thus inseparably adhering to the parent's nipple has given rise to the falacious but still very widely prevalent idea among the Australian settlers that the embryo marsupial is ushered into the world as a direct outgrowth from the mammary region.

At the present day, with the exception of the small group of the American Opossums and the Selvas, the entire assemblage of marsupials, comprising some 36 genera and 150 species, are, singularly to relate, exclusively found in Australia, New Guinea, and the few neighbouring islands recognised by systematic zoologists as pertaining to the Australasian region. What is more, this region of Australasia produces, with some few insignificant exceptions, chiefly rodents, no other indigenous mammals.

It is interesting to note that within the limits of this isolated and anciently founded marsupial order we have an epitome, as it were, of many of the more important groups of an equivalent classificatory value that are included among the higher mammalia previously described. In this relationship we find in the so-called Tasmanian Wolf, the Tasmanian Devil, and the "Native Cats" carnivorous and eminently predatory forms whose habits and general conformation are immediately comparable to those of the typical Carnivora. The Bandicoots, Banded Ant-eater, and Phascogales recall in a similar manner the higher Insectivora. In the tree-frequenting Opossums and Phalangers the external likeness and conformity in habits to the arboreal rodents is notably apparent, several of the species, moreover, possessing a parachute-like flying-membrane essentially identical with that which is found in the typical Flying-squirrels. An example in which the ground-frequenting or burrowing rodents are closely approached is furnished by the Australian Wombat, an animal which may be appropriately likened to an overgrown and lethargic Marmot. In this form, moreover, the rodent-like character of the dentition is especially noteworthy. The higher grass-eating mammals find their counterparts in the family group of the Kangaroos, in which, in addition to their essentially herbivorous habits, the contour of the head and neck, together with the expressive eyes and large expanding ears, are wonderfully suggestive of the various members of the Deer Family. The Cuscuses of New Guinea and the adjacent islands, both in form and habits, somewhat resemble their geographical neighbours, the Lorises, belonging to the Lemur Tribe, compared with which higher mammals, however, they possess the advantage of an eminently serviceable prehensile tail. The Australian Koala, or so-called "Native Bear," has been commonly compared by zoologists with the Edentate Sloths; while in the most recently discovered marsupial, the Pouched Mole, we have a counterpart, in both form and habits, of the familiar European species. Finally, in the small American section of the Marsupialia, we meet with a type--the so-called Yapock, or Water-opossum--in which the resemblances to an Otter, in both aspect and its aquatic habits, are so marked that the animal was originally regarded as a species only of the Otter Tribe.

The character of the _marsupium_, or pouch, differs materially among the various members of their order. It presents its most conspicuous and normal development in such animals as the Kangaroos, Wallabies, and the Australian Opossums or Phalangers. In the Tasmanian Wolf and the Bandicoots the pouch opens backwards. In such forms as the Phascogale, or Pouched Mouse, the pouch is reduced to a few rudimentary skin-folds, while in the Banded Ant-eater its position is occupied by a mere patch of longer hairs, to which the helpless young ones cling. On the same _lucus a non lucendo_ principle there is no trace of a pouch in the Koala, nor in those smaller species of the American Opossums which habitually carry their young upon their back. Even in these pouchless marsupials, however, the peculiar marsupial bones are invariably present, and in all other essential details their accord with the marsupial type of organisation and development is fully maintained.

THE KANGAROOS.

The typical and most familiar member of the Marsupial Order is the KANGAROO--the heraldic mammal of that vast island-continent in the South Seas, whose phenomenal advance by leaps and bounds, from what scarcely a century since was represented by but a few isolated settlements, has been aptly likened to the characteristic progression of this animal. Of kangaroos proper there are some twenty-four known species distributed throughout the length and breadth of Australia, extending southwards to Tasmania, and to the north as far as New Guinea and a few other adjacent islands.

In point of size the GREAT GREY KANGAROO and the RED or WOOLLY species run each other very closely. A full-grown male of either species will weigh as much as 200 lbs., and measure a little over 5 feet from the tip of the nose to the base of the tail, this latter important member monopolising another 4 or 4½ feet. The red or woolly species more especially affects the rocky districts of South and East Australia, while the great grey kind is essentially a plain-dweller and widely distributed throughout the grassy plains of the entire Australian Continent and also Tasmania. It is to the big males of this species that the titles of "Boomer," "Forester," and "Old Man Kangaroos" are commonly applied by the settlers, and the species with which the popular and exciting sport of a kangaroo hunt--the Antipodean substitute for fox-hunting--is associated. The pace and staying power of an old man kangaroo are something phenomenal. Our home country fox-hounds would have no chance with it; consequently a breed of rough-haired greyhounds, known as kangaroo-dogs, are specially trained for this sport. A run of eighteen miles, with a swim of two in the sea at the finish, and all within the space of two brief crowded hours, is one of the interesting records chronicled. The quarry, when brought to bay, is, moreover, a by no means despicable foe. Erect on its haunches, with its back against a tree, the dogs approach it at their peril, as, with a stroke of its powerful spur-armed hind foot, it will with facility disembowel or otherwise fatally maim its assailant. Another favourite refuge of the hunted "boomer" is a shallow water-hole, wherein, wading waist-deep, it calmly awaits its pursuers' onslaught. On the dogs swimming out to the attack, it will seize them with its hand-like fore paws, thrust them under water, and, if their rescue is not speedily effected, literally drown them. Even man, without the aid of firearms, is liable to be worsted in an encounter under these conditions, as is evidenced in the following anecdote.

A newly arrived settler from the old country, or more precisely from the sister island, ignorant of the strength and prowess of the wily marsupial, essayed his maiden kangaroo hunt with only a single dog as company. A fine grey boomer was in due course started, and after an exciting chase was cornered in a water-hole. The dog, rushing after it, was promptly seized and ducked; and Pat, irate at the threatened drowning of his companion, fired, but missed his quarry, and thereupon jumped into the water-hole, with the intention, as he afterwards avowed, "to bate the brains out of the baste" with the butt-end of his gun. The kangaroo, however, very soon turned the tables upon Pat. Before he had time to realise the seriousness of the situation he found himself lifted off his feet, and soused and hustled with such vigour that both Pat and his dog most narrowly escaped a watery grave. A couple of neighbours, by good luck passing that way, observed the turmoil, and came to the rescue. Between them they beat off and killed the kangaroo, and dragged Pat to land in a half-drowned and almost insensible condition. Pat recovered, and vowed "niver to meddle with such big bastes" again.

The doe kangaroos, while of smaller size and possessing much less staying power than their mates, can nevertheless afford a good run for horses and dogs, and are commonly known as "flyers." When carrying a youngster, or "Joey," in her pouch, and hard pressed by the dogs, it is a common thing for the parent to abstract her offspring from the pouch with her fore paws, and to throw it aside into the bush. The instinct of self-preservation only, by the discharge of hampering impedimenta, is usually ascribed to this act; but it is an open question whether the maternal one of securing a chance of escape for her young, while feeling powerless to accomplish it for herself, does not more often represent the actual condition of the case.

In proportion to the size of its body the kangaroo yields but a limited amount of meat that is esteemed for food. The tail represents the most highly appreciated portion, since from it can be compounded a soup not only equal to ordinary ox-tail, but by gourmands considered so superior that its conservation and export have proved a successful trade enterprise. The loins also are much esteemed for the table, but the hind limbs are hard and coarse, and only appreciated by the native when rations are abnormally short. "Steamer," composed of kangaroo-flesh mixed with slices of ham, represented a standing and very popular dish with the earlier Australian settlers; but with the rapid disappearance of the animal before the advance of colonisation this one time common concoction possesses at the present day a greater traditional than actual reputation.

The hunting of the kangaroo is conducted on several distinct lines, the method of its pursuit being varied, according to whether the animal is required for the primary object of food, for the commercial value of its skin, as a matter of pure sport, or to accomplish its wholesale destruction in consequence of its encroachments on the pasturage required for sheep- and cattle-grazing.

The greatest measure of healthy excitement in hunting the kangaroo, from the standpoint of pure sport, is no doubt to be obtained when running the marsupial down with horse and hounds in congenial company, as referred to on a previous page. The stalking of the animal single-handed on horseback or on foot, much after the manner of the deer, has also its enthusiastic votaries, and calls into play the greatest amount of patience and _savoir-faire_ on the part of the sportsman. It has been affirmed by a Queensland writer, "To kill kangaroos with a stalking-horse requires the practice of a lifetime, and few 'new chums' have the patience to learn it. It is, in fact, only stockmen, black-fellows, and natives of the bush who can by this method expect to make kangaroo-shooting pay." The horse which is successfully employed by experienced bushmen for stalking purposes is specially trained to its work, and, walking apparently unconcernedly in the direction of the selected quarry, brings the gunners, if they are experts in the art of keeping themselves well concealed, within easy range. In this manner two or three kangaroos are not infrequently shot in the same stalk, the animals having a tendency, on hearing the report of the gun, but not locating the direction from which it was discharged, to rush about in an aimless manner, and, as frequently happens, in the immediate direction of the hidden sportsman. In the good old times it is recorded that an experienced hand might kill as many as seventy or eighty kangaroos in a day by this stalking method. The marsupials are at the present date, however, so severely decimated that even in the most favourable settled districts a bag of from twelve to twenty head must be regarded as exceptional. Stalking the kangaroo on foot without the horse's aid is more strongly recommended to those to whom an occasional shot is considered sufficiently remunerative. Taking full advantage of intervening bushes and other indigenous cover, an approach to within a hundred yards or so of the quarry may be usually accomplished, though not quite so easily, perhaps, as might be at first anticipated. It is the habit of the kangaroo to sit up waist-high in the midst of the sun-bleached grass, which corresponds so closely in colour with its own hide that unless the animal is silhouetted against the sky-line it readily escapes detection.

The conditions under which the kangaroo is obtained for the main purpose of supplying the human commissariat is perhaps most aptly illustrated in connection with its chase as prosecuted by the Australian aborigines. In Tasmania and the Southern Australian States the primeval man is either extinct or more rare than the kangaroo. In the extreme north and far north-west, however, he still poses as "the lord of creation," and conducts his hunting expeditions on a lordly scale. The food-supply of the Australian native is essentially precarious. Long intervals of "short commons" are interspersed with brief periods of over-abundance, in which he indulges his appetite to its fullest bent. A kangaroo drive on native lines represents to the Australian mind one of these last-named superlatively memorable occasions. The entire tribe, men, women, and all capable youths, participate in the sport. Fires are lit by one section of the tribe, according to the direction of the wind, encircling a vast area of the country, while the other section posts itself in detachments in advantageous positions to intercept the terrified marsupials as they fly in the presumed direction of safety to escape the devouring element. Spears and waddies and boomerangs, in the hands of the expert natives, speedily accomplish a scene of carnage, and the after feast that follows may perhaps be best left to the imagination of the reader. The encroachments of neighbouring natives on the happy hunting-grounds that time and custom have conceded to be the sole monopoly of any one particular tribe is most strenuously resented, and constitute one of the commonest sources of their well-nigh perpetual inter-tribal battles.

A kangaroo battue, as carried into practice by European settlers in those few remaining districts where the animal is sufficiently abundant to constitute a pest by its wholesale consumption of the much-prized pasturage, is far more deadly in its results to the unfortunate marsupials. Existing sheep-fences, supplemented by a large suitably enclosed yard, are first specially prepared for the reception of the expected victims. All the settlers, stockmen, and farm hands from the country round are pressed into service, and assemble on horseback or on foot at the appointed rendezvous at break of day. A widely spreading cordon of beaters being told off, a systematic drive is then commenced, which results in all the animals being driven towards and collected within the enclosed yard. The culminating scene is one of wholesale slaughter with club and gun. From these battues none of the unfortunate animals escape, as they are so closely hemmed in.

The first record of the existence of the kangaroo, coupled with its characteristic name, is found associated, it is interesting to observe, with the history of one of the earlier voyages of Captain Cook. The neighbourhood of Cooktown, in Queensland, claims the honour of supplying the first example of the animal which was brought to Europe and astonished the zoologists of that time by the singularity of its form and reported habits. Captain Cook happened--in July, 1770--to be laying up his ship, the _Endeavour_, for repairs, after narrowly escaping total wreck on the neighbouring Great Barrier Reef, in the estuary of the river subsequently coupled with his ship's name. Foraging parties, dispatched with the object of securing, if possible, fresh meat or game for the replenishment of the ship's well-nigh exhausted larder, returned with reports of a strange creature, of which they subsequently secured specimens. Skins were preserved and brought to England, but it was some little time before the zoological position and affinities of the creature were correctly allocated. By some naturalists it was regarded as representing a huge species of Jerboa, its near relationship to the previously known American Opossums being, however, eventually substantiated. The closer acquaintanceship with the peculiar fauna of Australia that followed upon Captain Cook's memorable voyage of discovery along the coast-line of that island-continent soon familiarised naturalists with many other of the allied species of which the kangaroo constitutes the leading representative.

Some considerable amount of obscurity is associated with the prime origin of the animal's almost world-wide title of "Kangaroo." It is most commonly accepted as representing the native name for the creature in that Queensland district from whence it was first reported by Captain Cook. No later investigations and enquiries have, however, in any way established the correctness of this hypothesis, those explorers who have made a special study of the dialects and habits of the aboriginal inhabitants entirely failing to elicit anything even remotely coinciding with the name in question. It has, in fact, been reluctantly concluded by one of the most experienced Queensland authorities on these matters that the name originated as a mere miscomprehension of the information elicited from the natives. Verbal communication with the native tribes under the most favourable circumstances is liable to a vast amount of misunderstanding, and where other than linguistic experts are present it frequently happens that much mongrel or "pidgin English" gets mixed up with the native terms. Assuming this to have been the case in the present instance, it has been suggested that the name of Kangaroo, or "Kanguroo," as it was originally spelt, implied some form of negation of the knowledge which the enquiring white man was seeking to elicit, or, maybe, partly even a phonetic and parrot-like repetition of the constantly recurring query that was doubtless current among the "handy men" of the _Endeavour's_ commission, such as "Can you" tell me this or that concerning the many unfamiliar objects that greeted the eyes of the new arrivals in this strange land. The writer retains a vivid recollection of a closely analogous manner in which the rural inhabitants of Vigo Bay, on the Spanish coast, appropriated a common phrase used by the crew of the yacht with whom he landed there. Having evidently noted that the two words "I say" prefaced the majority of Jack-tar's speeches, this catch-phrase was adopted and applied by them as a greeting and as a reply to almost every interrogation in dumb-show or otherwise that was addressed to them. An unknown animal submitted to these rustic Solons would doubtless have been dubbed the "I say"; and had the land been a new one--say, somewhere in the South Seas--that name would probably have stuck to it. Applying this interpretation to the kangaroo, and bearing in mind the fondness of the Australian native to duplicate his name-words or syllables--e.g. _wagga-wagga_, _debil-debil_, and so forth--the "Kang-you-you" or a closely resembling phonetic expression would present itself to the native mind as a much more correct rendering of the simpler "Can you" or "Kang you" which he had picked up as a catch-phrase from the _Endeavour's_ crew. In the absence, at all events, of any more rational interpretation of the mystery, this one would seem to merit consideration.

While the kangaroo is being speedily dethroned from the dominant position it originally occupied in the indigenous Australian fauna, praiseworthy and highly successful attempts have been made to acclimatise this marsupial on British soil. At Tring Park, Lord Rothschild's estate, Woburn Abbey, and elsewhere, troops of these graceful creatures may be seen under conditions of happiness and liberty scarcely inferior to those by which they are environed in their native "bush."

Of smaller members of the Kangaroo Family, there are some thirty distinct forms, popularly known in Australia as WALLABIES, WALLAROOS, PADDY-MELONS, POTOROOS, KANGAROO-HARES, KANGAROO-RATS, etc. The wallabies, which represent the most important group with regard to their larger size and economic utility, number some fourteen or fifteen species, and are distinguished, with relation more especially to their habitats or peculiar structure, as ROCK-, BRUSH-TAIL, and SPUR-TAIL WALLABIES, etc. Among the rock-wallabies the yellow-footed species from South Australia is undoubtedly one of the handsomest as well as the largest member of its group, the uniform grey characteristic of the majority of its members being in this instance represented by an elegantly striped and banded form, in which the several tints of brown, yellow, black, and white are pleasingly interblended. A very fine example of this wallaby was included in the valuable collection of animals, formerly at Windsor, recently presented to the Zoological Society by His Majesty King Edward, and is now on view at the Regent's Park. The successful stalking of rock-wallabies in their native fastnesses entails no mean amount of patience and agility. Although these animals are so abundant in favoured localities as to make hard-beaten tracks to and fro betwixt their rock-dwellings and their pasture-grounds, one may traverse the country in broad daylight without catching a glimpse of a single individual. One species, about the size of a large rabbit, is very plentiful among the rocky bastion-like hills that border the Ord River, which flows into Cambridge Gulf, in Western Australia. Efforts to stalk examples in broad daylight proved fruitless; but by sallying out a little before daybreak, so as to arrive at their feeding-grounds while the light was still dim, the writer succeeded in securing several specimens. Many of these rock-wallabies are notable for the length, fine texture, and pleasing tints of their fur, their skins on such account being highly esteemed for the composition of carriage-rugs and other furry articles.

Of the larger brush or scrub varieties, the species known as the BLACK WALLABY is the most familiar form. It is particularly abundant in the Southern Australian States, and also in Tasmania. Its flesh is excellent eating, and, dressed and served up in the orthodox manner of jugged hare, can scarcely be distinguished from that toothsome dish. Some of the smaller species, such as the hare- and rat-kangaroos or potoroos, are, as their names denote, of no larger dimensions than the familiar rodents from which they are popularly named. Several of these smaller species, including notably the potoroo, or kangaroo-rat of New South Wales, are addicted to paying marked attention to the settlers' gardens, and, being to a large extent root-feeders, have acquired a special predilection for the newly planted or more fully matured potato crops.

The most abnormal group of the Kangaroo Family is undoubtedly that of the TREE-KANGAROOS, formerly supposed to have been limited in its distribution to the island of New Guinea, but which has within recent years been found to be represented by one or more species in Northern Queensland. At the Melbourne Zoo they have been found, except in the coldest weather, to thrive well in the open--a moderate-sized tree, with a small fenced-in enclosure around it, being admirably suited to their requirements, at the same time providing a most instructive exhibition of their peculiar forms and idiosyncrasies. Seen at its best, however, the tree-kangaroo, or "boongarry," as it is known amongst the Queensland natives, is a most clumsy, melancholy-looking beast, which has apparently found itself "up a tree," not as the outcome of its personal predilections, but owing to the _force majeure_ of untoward pressure in the form either of relentlessly persecuting enemies or the failure of its normal terrestrial commissariat. Compared with the graceful and superlatively agile tree-frequenting phalangers, between whom and the ordinary kangaroos it has been sometimes, but erroneously, regarded as representing a connecting-link, the boongarry presents a most ungainly contrast. Its climbing powers are of the slowest and most awkward description, the whole of its energies being concentrated on its endeavour to preserve its balance and to retain a tight hold upon the branches of the trees it frequents, and to which it clings with such tenacity with its long sharp claws that it can with difficulty be detached. In its wild state, moreover, these claws can be very effectively used as weapons of defence; and hence the natives, with whom the animal is highly esteemed as an article of food, are careful to give it its quietus with their clubs or waddies before venturing to handle it. The tree-kangaroos inhabit the densest parts of the forests or "scrubs" of New Guinea and tropical Queensland, and appear to confine their movements chiefly to the trees of moderate size, or the lower branches only of the taller ones.

The species which constitutes the most natural known connecting-link between the typical Kangaroos and the family of the Phalangers, next described, is the FIVE-TOED RAT-KANGAROO, or POTOROO. As its name implies, it is a small creature of rat-like aspect and dimensions, and possesses, like a rat, a long, cylindrical, naked, scaly tail. It is the structure of the feet, however, that constitutes the important distinction. In place of the four toes only to the hind limbs it possesses the full complement of five, and the first toe, moreover, is set farther back, and is opposable for grasping purposes. This animal is from Queensland.

THE PHALANGERS.

The Phalanger Family of Marsupials, which next invites attention, is constituted of animals especially adapted to lead an arboreal life, though among themselves they exhibit very considerable structural variations. The species usually placed at the head of this group is the essentially droll and in many respects abnormal form known as the KOALA, or AUSTRALIAN NATIVE BEAR. Its little podgy tailless body, short thick-set head, and round tufted ears lend some countenance perhaps to the ursine analogy; but there the likeness ends.

The koala is limited in its distribution to the south-eastern region of the Australian Continent, and is there found inhabiting the loftiest gum-trees, on the leaves and flowers of which it almost exclusively feeds. Compared with the opossum and squirrel-like phalangers, the koala is a very slow and sedentary little animal, remaining stationary in and browsing upon the leaves of the same gum-tree for days or even weeks at a stretch. Taking advantage of this home-staying propensity, examples are established, with full liberty to wander at will among the large gum-trees, in the Melbourne Zoological Gardens, and have never abused the confidence reposed in them by surreptitiously absconding. The young koalas in particular make the most droll and delightful of household pets, speedily becoming attached to and following their owners about the premises, or contentedly settling down to the possession of an allotted corner of the verandah, in which an improvised perch has been erected and a constant supply of its favourite gum-leaves is daily assured. One such example, kept in Brisbane, Queensland, furnished the writer with the material for the photograph on this page; also of another one that illustrated in an interesting manner the very singular attitude assumed by the animal when asleep. Instead of creeping into the hollow trunk or spout of a gum or other tree, as the opossums and other phalangers are wont to do, the little "bear" simply sticks tight to his supporting branch, and, tucking in his head and ears and limbs, converts himself into an apparently homogeneous rounded mass of fur or moss, and, thus disguised, peacefully sleeps. Seen at some little distance, in fact, none but a trained eye could distinguish this sleeping bear from one of the round woody excrescences or bunches of misletoe-like parasitic growths that are of common occurrence on the trees in every gum forest. In this way the little creature secures immunity from the attacks of enemies by mimicking the characteristic peculiarities of its environment, as obtains so generally among insects and other of the lower orders of animated nature. A closely analogous sleeping attitude, it may be mentioned, is assumed by one of the African lemurs or pottos, which have been dealt with in a previous chapter.

Although in captivity the koala takes kindly to a mixed diet in which bread-and-milk and fruit may form substantial elements, it can rarely be induced to altogether dispense with its customary gum-leaf regimen, and it is this circumstance that mainly accounts for its rarity in European menageries. Time and again, however, this interesting animal has put in an appearance at the Regent's Park; but in spite of Kew Gardens and other sources being laid under contribution for a supply of gum-tree leaves, its sojourn there has been but brief. As a matter of fact, the common or blue gum-tree, which is alone cultivated and available in any quantity in this country, and which is indigenous to Tasmania, is not the species on which the koala is accustomed to feed. Of gum-trees there are some hundred species, every one differing in the peculiarity of its aromatic scent and flavour, and having its special clientèle among the ranks of leaf-browsing animals. So far as the writer's observations extended, it was the big Queensland "white" and "swamp" gums that were especially patronised by the Australian bears, and these are not grown in England.

Although at first sight, and normally so far as the younger individuals are concerned, the koala would appear to represent the most perfect embodiment of peace and goodwill among mammals, he is accredited at a maturer age, when crossed in love or goaded to resentment by some other cause, to give way to fits of ungovernable rage. These temporary lapses are, however, very transient, and our little friend soon recovers his customary bland placidity. While it is being threshed out, nevertheless, the "burden of song" delivered by rival claimants for a partner's favours is a remarkable phenomenon. The circumstance that the vocal duet is commonly executed high up among the branches of the loftiest gums no doubt adds very considerably to both the timbre of the "music" and the distance to which it is carried. The old-time phrase of "making the welkin ring" would undoubtedly have been applied with alacrity and singular appropriateness by the poets of the departed century to the love-song of the koala, had they been privileged to hear it.

Among the examples of the koala which have been in residence at the Zoo, one of them came to a pathetic end. As told to the writer by Mr. A. D. Bartlett, the late superintendent, it appears that the little animal, on exhibition in the gardens during the day, was brought into the house at night, and allowed the run of a room which, among other furniture, included a large swing looking-glass. One morning the little creature was found crushed to death beneath the mirror, upon which it had apparently climbed and over-balanced. The information that the animal was a female evoked the suspicion that personal vanity and the admiration of its own image in the glass had some share in compassing its untimely end. Possibly, however, it hailed in the reflection the welcome advent of a companion to share its lone banishment from the land of the gum-tree, and in its efforts to greet it thus came to grief.

The female koala produces but one cub at a time. At an early period after its birth this is transferred to its mother's back, and is thus transported until its dimensions are about one-half of those of its parent. The pair as shown in the illustration on page 355 presents, under these conditions, an essentially grotesque aspect.

It is a noteworthy circumstance that, compared with the male, the female koala is but rarely to be observed wandering abroad during broad daylight. As with the typical phalangers food is consumed chiefly at night or during the brief Australian twilight hours. While the male at certain periods, more especially the months of March and April, is much in evidence in daytime to both the senses of sight and hearing, as attested to on a previous page, the female spends the whole or greater portion of the day clinging as an inert sleeping mass to a convenient branch. "Bear"-shooting in Australia, as might be anticipated from the description here given of the animal's habits and temperament, affords but sorry sport. It may further be remarked that those who have shot at and only disabled one of these inoffensive little creatures are scarcely likely to repeat the experiment. The cry of a wounded koala has been aptly compared to that of a distressed child, but still more pathetic. When fatally shot, it also more frequently than otherwise clings tenaciously back-downwards, like the South American sloths, to the supporting tree-branch, and is thus frequently irrecoverable. With the non-sentimental Australian furrier the koala's pelt of soft, crisp, ashy-grey fur is unfortunately in considerable demand, being made up mostly, with the quaint round head and tufted ears intact, into, it must be confessed, singularly attractive and warm rugs.

The correspondence of the koala in form and habits to the sloths among the higher mammalia has been previously mentioned. The parallelism might be pursued in yet another direction. In earlier times the small tree-inhabiting South American sloths were supplemented by ground-frequenting species, such as the Megatherium, which were of comparatively titanic proportions. The epoch of the accredited existence of these huge ground-sloths was so comparatively recent--the later tertiaries--that it is even yet not regarded as altogether improbable that some existing representative of the race may yet be discovered in the fastnesses of the South American forests, and thus claim a niche in the pages of a subsequent edition of "LIVING ANIMALS." In a like manner the little sloth-like tree-frequenting "Australian Bear" had his primeval ground-dwelling colossi, and there is yet a lurking hope among enthusiastic zoologists that some surviving scion of the little koala's doughty forebears may yet turn up in the practically unexplored Central Australian wildernesses. Some such anticipations, as a matter of fact, stimulated the hopes and aspirations of the participators in one of the latest of these exploring expeditions, which, while not successful in this instance in obtaining so great a prize, secured for science that most interesting and previously unknown marsupial mammal the Pouched Mole.

THE TYPICAL PHALANGERS.

The typical PHALANGERS, or OPOSSUMS, as they are familiarly known throughout Australia, include a very considerable number of representatives, ranging in size from that of a small mouse to that of a full-grown cat. All are essentially arboreal in their habits, feeding principally on the leaves and flowers of the various gums. They are for the most part strictly nocturnal in their habits, and make their homes and retiring-places during the day in the hollow trunks and limbs that are of such abundant occurrence in the periodically fire-swept Australian forests. Almost all the larger species are notable for the length, thickness, and exquisitely fine texture of their fur, a circumstance for which they are consequently laid under heavy penalties for the sake of their pelts. The island colony of Tasmania, in the extreme south, with its colder climate, as might be anticipated, produces the finest qualities of these furs, that of the BLACK or SOOTY OPOSSUM, which is peculiar to the island, being most highly prized. The length and furry character of their in many instances prehensile tails also form a conspicuous feature of this group. Nature, in fact, apparently distributed caudal material so over-liberally among these marsupials that the little koala had to make shift without.

The group of the Phalanger Family popularly known as FLYING-SQUIRRELS, or more correctly as FLYING-PHALANGERS, is almost universally admitted to include some of the most beautiful of living mammals. In external structure, so far as their peculiar so-called "flying" mechanism is concerned, these animals coincide in a remarkable manner with the true flying-squirrels, belonging to the Rodent Order, indigenous to the Asiatic and American Continents. In neither instance is there flight, in the true sense of the term, similar to that of birds and bats, but the fore and hind limbs are connected by a parachute-like membrane, which, outstretched when the animal leaps from tree to tree, buoys it up and enables its owner to traverse, in a straight and gradually descending line only, very considerable distances.

The smaller squirrel-like form common to the south-eastern districts of Australia, and on account of its predilection for sweets commonly known as the SUGAR-SQUIRREL, makes a most charming little pet. For the most part addicted to sleep, and impatient at being disturbed during the day, towards sundown it wakes up, and is full of frolic. One such example was the writer's travelling companion for a considerable interval in Western Australia. While remaining packed conveniently away in a small box throughout the day, it was accustomed to enjoy the liberty of whatever apartment its owner occupied in the evening and throughout the night, returning of its own accord to its sleeping-box with the approach of dawn. On one exceptional occasion, however, Master Tiny, as this individual was named, was missing in the morning from his accustomed crib, and a prolonged search and examination of every corner and article of furniture that could afford shelter failed to recover him. That the little creature was lost through some one having unwittingly left the door of the apartment open, permitting its escape, was the only and much-deplored conclusion that could be arrived at. Towards evening, however, there was a slight rustle close at hand, and Master Tiny was discovered emerging, like Minerva from the head of Jupiter, from the top of one of the old-fashioned china dogs that decorated the hotel-room mantelpiece. The ornament, seemingly intact from the front, had the back of the head battered in. Through the resulting crevice the little animal had managed to squeeze itself, having come to the conclusion, doubtless, that this newly chosen retreat more nearly resembled the cavernous shelter of its native tree-spout than its accustomed artificially constructed box. This singular domicile Master Tiny was permitted to monopolise for the remainder of his sojourn at that hostelry. One of the favourite diversions of this little phalanger during the evenings was to climb up the curtain and cornice of the room he occupied, and thence hurl himself through the air with outspread parachute to the writer at the opposite end. The apartment, happening to be the commercial room of the hotel, some thirty feet in length, gave him good scope for exercising his characteristic flying leaps. The attitude invariably maintained during these flights is aptly illustrated in the accompanying photograph; the body is never poised with the head inclined downwards, as is commonly depicted in artists' fancy sketches of the animal contained in popular natural histories. A friend of the writer's in Tasmania, who kept one of these flying-phalangers as a household pet, was accustomed to leave a crevice of the window open at night, so that the little fellow could go in and out as it liked. After the manner of most pets, however, a day arrived upon which its box was found vacant, a marauding cat or other disaster having apparently compassed its untimely end.

The larger flying-phalanger, the dimensions of our domestic tabby, and with fur as long and as soft as the Persian variety, is less frequently domesticated. It has, in fact, an evil reputation for scratching, biting, and general untamableness. One that was kept for some little time by the late Dr. Bennett, of Sydney, and brought to England, never entirely lost its innate savagery. On the voyage from Australia it became sufficiently tame as to be allowed occasionally to run about on the deck, and was so far amiable as to lay on its back and permit itself to be tickled. On attempting to handle it, however, "it displayed its usual savage disposition, digging its sharp claws and teeth into the bands of its captor." The writer was fortunate in being the recipient in Queensland of a couple of these large phalangers which were exceptions to the usual rule. These specimens--a mother and its young male offspring--also varied in colour from normal examples, which are usually dark slate or blackish brown above and whitish underneath. The mother in this instance was a beautiful cream-white throughout; and her young one, while dark chinchilla-grey upon the back, limbs, and tail, had white ears and breast. Both were very friendly, and would of their own accord climb over their owner's person, seeking in his pockets for hidden lumps of sugar and other acceptable dainties. As with the smaller squirrel-like forms, they slept throughout the greater portion of the day, waking to activity and making excursions in search of their food as soon as the sun went down. The tail of this species of phalanger is abnormally long and furry, but not prehensile. It was observed of them that when feeding leisurely on the gum-tree leaves this appendage was permitted to hang or rest loosely, but that when walking along the branches they would very frequently coil this member into a tight spiral coil, like a watch-spring or the proboscis of a butterfly, against their hindquarters. This phenomenon is apparently unique among mammals. Although generally seeking the darker retreat of their box for their long daylight sleep, the female, more particularly, would frequently simply curl herself up into a furry white ball in one corner of the cage, the head, limbs, or other features being at such times altogether indistinguishable. The aid of the magnesium flash-light was successfully called into service to secure the photographic likeness of this animal, here reproduced, which was taken while it was enjoying its evening meal.

As previously mentioned, some representatives of the flying-phalanger group are no larger than mice, and are furnished in a similar manner with a parachute-like membrane that enables them to take abnormally long flying leaps, or as it were to sail horizontally through the air. The PYGMY FLYING-PHALANGER, whose length of body does not exceed 2½ inches, is one of the most interesting. The tail in this form is also adapted for aerial flotation, the long hairs that grow upon this appendage being arranged in two parallel lines like the vanes of a feather. Its distribution is limited to the south and eastern districts of the Australian Continent. There are also a number of mouse- and squirrel-like phalangers destitute of the flying-membrane, which in this respect very closely resemble in external aspect more typical members of the Rodent Order. One form in particular, the STRIPED PHALANGER of New Guinea, decorated with broad longitudinal black and white stripes, is singularly suggestive of some of the variously striped American squirrels. This interesting island of New Guinea also produces a little PYGMY PHALANGER with a feather-like tail which, except for the absence of a parachute or flying-membrane, is the very counterpart of the Australian kind. Another species, which in shape, size, and more especially with reference to its long, pointed snout, closely resembles a shrew-mouse, is found in Western Australia. The tail of this species, known as the LONG-SNOUTED PHALANGER, is highly prehensile; and it is also provided with a long, slender, protrusile tongue, with which it abstracts the honey from Banksias and other flowers, upon which it customarily feeds.

The two large phalangers known as the BLACK and GREY or VULPINE OPOSSUMS, which are chiefly laid under contribution for the Australian fur supplies, are provided with prehensile tails, the under side of the extremity of which grasps the supporting fulcrum and is devoid of hair. The adaptation of the tail for use as a fifth hand--as in the New World monkeys--is, however, much more conspicuously manifested in what are known to the colonists as the RING-TAILED OPOSSUMS, and to zoologists as CRESCENT-TOOTHED PHALANGERS. In these the tail tapers to a fine point, and the hair throughout the terminal third of this appendage is so fine and short that it at first sight presents the appearance of being entirely naked. This terminal third of the tail, moreover, in the greater number of species, contrasts with the remaining portion by being white in hue. It occasionally happens, however, that individuals occur which are entirely white. One such which came into the writer's possession was obtained from the Bruni Islands, in the Derwent Estuary, Tasmania, and afterwards became a great pet with the young people at Government House, Hobart. It is an interesting circumstance that the Bruni Islands were noted for the production of albino animals of various descriptions, white kangaroos and white emus having also been obtained from this locality. Probably some peculiarity of the soil, and its action on the vegetable food the animals consumed, played an important part in the unusually frequent occurrence of this phenomenon.

The ring-tailed opossums differ essentially from the common opossum or phalanger and its allies in their life habits. While these latter habitually take up their abode and bring forth their young in hollow trees, the ring-tailed species construct a regular nest of interlaced sticks, leaves, grass, or any other available material for their domicile. The structure much resembles the nest, or "drey," of our own familiar European squirrel, and may be perched high up among the tree branches or within only a few feet from the ground among the scrub thickets. In New Guinea a variety of these ring-tailed phalangers occurs, not found in Australia, which has no white tip to its tail, and the ears are very short and wide. The group as represented by this species leads to the consideration of the so-called CUSCUSES or typical phalangers indigenous to New Guinea and North Queensland, though but rarely seen there, which, as an exception to the Marsupial Tribe, are distributed among the Indo-Malay Islands as far westward as Celebes. In the cuscuses the tail is altogether naked, and pre-eminently prehensile throughout almost its entire terminal moiety; the ears are round and, proportionately, exceedingly small; while the fur is very short, thick, and woolly. Compared with the opossums or phalangers, the cuscuses are very dull and sluggish in their movements, creeping slowly among the branches of the trees to browse on the fruit and leaves which constitute their principal diet. Like the opossums, however, or even to a greater extent, they vary this vegetarian regimen with insects or an occasionally captured bird.

THE CUSCUSES.

The familiar SPOTTED CUSCUS of New Guinea is the most ornate marsupial mammal. The males, more especially, are as variegated in colour as a tortoiseshell cat, their tints, moreover, closely corresponding in hue with those of the feline. No two individuals, however, are precisely alike in this respect. Usually the ground-colour of the back is a dirty or creamy white, interspersed with various-shaped blotches of nut-brown or black; the chin, breast, and under-parts are a purer white, and the limbs grey or reddish brown, or, as shown in the photograph over-leaf, mottled like the body. The BLACK CUSCUS of Celebes is, as its name denotes, a much more sombre-looking animal, and is also the largest species, its dimensions equalling or exceeding those of a large cat. The uniformly tinted GREY CUSCUS of Timor, Amboina, and other of the Indo-Malay Islands is very similar in size and aspect, excepting for the half-naked tail, to the common ring-tailed phalanger. All the cuscuses are of rare occurrence in even their most favoured habitats. On one occasion the writer came across an example of the grey species in the scrub forest of Thursday Island, Torres Straits. In this instance, however, it is doubtful if the animal was not an escaped pet brought over from the neighbouring coast of New Guinea.

Much interesting information concerning different varieties of the cuscus is contained in Dr. Alfred Wallace's interesting work "The Malay Archipelago." An anecdote of one which was brought to this naturalist during his residence in the Aru Islands--the headquarters of the great bird of paradise--is thus related: "Just as we had cleared away and packed up for the night, a strange beast was brought, which had been shot by the natives. It resembled in size and in its white woolly covering a small fat lamb, but had short legs, hand-like feet with large claws, and a long prehensile tail. It was a Spotted Cuscus, one of the curious marsupial animals of the Papuan region, and I was very desirous to obtain the skin. The owners, however, said they wanted to eat it; and though I offered them a good price, and promised to give them all the meat, there was great hesitation. Suspecting the reason, I offered, though it was night, to set to work immediately, and get out the body for them, to which they agreed. The creature was much hacked about, and the two hind feet almost cut off, but it was the largest and finest specimen of the kind I had seen; and after an hour's hard work I handed over the body to the owners, who immediately cut it up and roasted it for supper."

The remarkable tenacity of life possessed by the cuscus is fully attested to by Dr. Wallace. He says: "They move about slowly, and are most difficult to kill, owing to the thickness of their skins and tenacity of life. A heavy charge of shot will often lodge in the skin and do them no harm, and even breaking the spine or piercing the brain will not kill them for some hours. The natives everywhere eat their flesh; and as their motions are so slow, easily catch them by climbing; so that it is wonderful that they have not been exterminated. It may be, however, that their dense woolly fur protects them from birds of prey, and the islands they live in are too thinly inhabited for man to be able to exterminate them."

One of the most notable circumstances respecting the cuscus is the fact that it is one of the few marsupials whose geographical distribution extends so far east in the Malay Archipelago as to be found associated with many of the higher mammalia which are altogether unrepresented in Australia or New Guinea. The Moluccas, including notably the islands of Silolo, Ceram, Boru, and many smaller ones, for example, produce no less than three species of cuscus, and are also the home of a species of baboon, a civet-cat, a deer, and that remarkable pig the babirusa. One other marsupial, a little flying-phalanger, is likewise a denizen of these islands. It has been suggested by Dr. Wallace that none of the foregoing higher mammals are possibly indigenous to the Moluccas. The baboon, he remarks, is only found in the island of Batchian, and seems to be much out of place there. It probably originated from some individuals which escaped from confinement, these and similar animals being often kept as pets by the Malay inhabitants and carried about in their praus. The civet-cat, which is more common in the Philippines and throughout the Indo-Malay region, is also carried about in cages from one island to another, and not infrequently liberated after the civet has been abstracted from them. The deer, which is likewise tamed and petted, its flesh also being much esteemed for food, might very naturally have been brought by the Malays from Java with the express object of its acclimatisation. The babirusa, whose headquarters are in the island of Celebes, is only found in Boru, its nearest neighbour in the Moluccan group. Dr. Wallace anticipates that these two islands were in former times more closely connected by land, and that under such conditions the babirusa may have swum across the intervening channel. Should these several hypotheses be correct, the Molucca Islands must be regarded, from a zoological standpoint, as an essentially Australasian or marsupial-producing region.

THE WOMBATS.

The Wombat Family, claiming the next position in the marsupial galaxy, constitutes the very antithesis to the light and graceful arboreal phalangers. There are but three known species, one of these inhabiting Tasmania and the adjacent islands, while the other two are peculiar to the southern region of the Australian Continent. In forms and gait their thick-set tailless bodies suggest a cross between a small bear and a capybara, and as "bears" and "badgers" they are familiarly known by the Australian colonists. The badger simile is perhaps the most pertinently applied with reference to their habit of excavating huge earth-burrows as dwelling-places, and out of which they customarily emerge only at night to feed. The TASMANIAN WOMBAT, at all events, is essentially gregarious in its habits; In the neighbourhood of Swansea, on the east coast, it is, or was, particularly abundant, forming regular warrens among a light undergrowth of vegetation, through which travelling on horseback is a distinctly risky proceeding. The temperament of the wombat is peculiarly placid; and hence, as it might be anticipated, they are essentially long-lived. One, Charlie by name, which has been domiciled at the Zoo for the past thirty years, is still hale and hearty, and evidently disinclined yet awhile to immolate himself on the altar of fame as a much-needed successor to the antique effigy which has for so long represented his species in the British Natural History Museum. Waiting for dead men's shoes is a proverbially tedious task, and for a coveted wombat's skin evidently more so.

The tough hide, with its thick, harsh fur, of the Tasmanian wombat, or "badger," as it is locally dubbed, is somewhat highly prized in the land of its birth. For floor- and door-mats and rugs the pelt is practically indestructible; and as such, though scarcely a thing of beauty, the special pride of the thrifty housewife. This animal is also not infrequently made a household pet, and will waddle as complacently as an over-fed poodle around the premises after its owner. The wombat, like the large majority of the marsupial animals, is for the most part nocturnal in habits, and a strict vegetarian.

The wombats present several interestingly distinct structural peculiarities. In the first place, their teeth, which are twenty-four in number, all grow uninterruptedly throughout life, and are consequently devoid of roots. The incisor teeth are represented by but a single pair in each jaw, and, having enamel only on their front surfaces, wear away in a chisel-like form, as in the beavers and other rodents. Superficially in both form and habits, as well as in the character of their dentition, the wombats may in fact be aptly likened to some unwieldy representative of the Rodent Order. Another structural peculiarity of the wombat is that it is the proud possessor of two more pairs of ribs than any other marsupial.

Of the three known species, the COMMON WOMBAT of the South and Eastern Australian States is the largest, attaining to a length of as much as 3 feet. The colour of this form is subject to considerable variation, being sometimes yellow, yellow more or less mixed with black, or completely black. Albinism, as in the kangaroos and phalangers, is of apparently rare occurrence. The hair, while coarse, is less so than in the Tasmanian species. What is known as the HAIRY-NOSED WOMBAT, inhabiting South Australia, is intermediate in size between the common and the Tasmanian varieties; its most distinctive features are the soft and silky character of its brownish hair, and its longer and more pointed ears. The coarseness of the hair of the Tasmanian species has been previously referred to; in colour it is most usually a dark greyish brown, while the ears are small and rounded.

The flesh of the wombat is somewhat esteemed for food, being regarded by some as equal to pork, and much resembling it in flavour. The predilection of tame specimens for milk is very strong, and it has been recorded of one animal that it was not only in the habit of seeking out the milk-pans and pushing off the covers in order to drink the contents, but afterwards of taking a bath in what was left.

A remarkable habit has been accredited to the wombat which invites scientific investigation. It is said to be capable of sustaining life for an abnormally long period under water, and that when in the course of its travels it meets with a pond or river it does not attempt to swim, but, deliberately entering the water, walks along the bottom, and so emerges on the opposite bank.

The animals of Australia living in not very remote geological times included a near ally of the wombat which equalled a tapir in dimensions.

THE BANDICOOTS.

The Australian BANDICOOTS--not to be confounded with their namesake of India, which is a big rat--constitute a very distinct little family group. They number in all some eight or nine species, distributed throughout the length and breadth of Australia and Tasmania, and found also in New Guinea. The largest member is about the size of a rabbit; and as its general shape, long ears, and soft silky hair impart some slight resemblance to that rodent, it is commonly known as the RABBIT-BANDICOOT. With the above-enumerated points, however, the likeness ceases--its possession of a moderately long tail, pointed snout, and feet modified on a plan closely resembling those of the kangaroo's indicating its essentially distinct nature. In a second variety, having somewhat the same external contour, but smaller in size, the fore limbs are very short, and the feet so modified that only two toes are visible externally. With reference to this peculiar feature, it is known as the PIG-FOOTED BANDICOOT. In a third kind of similar dimensions, with harsh brown fur, the ears are comparatively short, and the snout is so abnormally prolonged that, it has been appropriately named the LONG-NOSED BANDICOOT. Superficially, in point of fact, this and other allied species so closely resemble certain of the long-snouted insectivorous mammals, such as the Tenrec and Solenodon, that they might be excusably mistaken by the non-scientific for members of the same group. The bandicoots are chiefly nocturnal, and at all events incorrigible "sun-downers," turning up for their meals when the evening shadows fall, and taking a heavy and unwelcome toll of the farmers' potatoes, beets, or other root, crops. Like the wombat, already described, they are earth-burrowers. Some of them, however, construct nests above-ground in long coarse grass or low tangled shrubs, which are so ingeniously built in accord with their environment as to readily escape detection. Insects and worms, in addition to a main diet of vegetable matter, contribute to the bandicoot's somewhat heterogeneous menu.

The wood- and root-boring larvæ of a moth which infests the Australian wattle- or acacia-trees are a very favourite food with several of the species, and it is worthy of remark that the bandicoots are not alone in displaying a penchant for this delicacy. Under the title of "bardies" they are collected and highly esteemed for food by the natives of Western Australia, who eat them either cooked or raw. These larvæ are, moreover, acceptable to many European palates, and the writer has witnessed little faggot-like bundles of them brought round by the natives to the hotels at Geraldton, Western Australia, for sale or barter to chance customers. It may be observed in this connection that the analogous wood-boring larvæ of the goat-moth, which were kept and specially fattened for the occasion, constituted one of the dainty dishes of the luxurious Romans.

One of the commonest species found in Tasmania is known as the BANDED or STRIPED-BACKED BANDICOOT, being so named on account of the characteristic markings of its fur. The general ground-colour of the coat is an almost equal admixture of black and yellow hairs, the black tint, however, prevailing on the back, and the lighter one on the sides. The hindquarters are, however, variegated by the presence of some three or four broad transverse stripes that are almost entirely black, while the intervening spaces are a light whitish yellow. A few shorter stripes are sometimes continued as far as the root of the tail, this appendage also having a dark line running along its upper surface. The head is of a somewhat lighter tint than the remainder of the body, while the breast, abdomen, and feet are white, slightly tinged with grey. The transversely striped pattern of ornamentation of the hindquarters of this bandicoot is of interest with relation to the circumstance that a similarly located banded variegation of the fur occurs also in the Tasmanian wolf, or thylacine, and in the banded ant-eater, described in a following section. As a colour-pattern it would appear to be quite peculiar to these marsupials, no such restriction of the markings occurring among the higher or placental mammals. In the South African suricate, a member of the Ichneumon Tribe, in which the nearest approach to this dorsal banding is met with, the stripes are equally developed as far forward as the base of the neck.

Both the banded and other species of bandicoots are extremely swift and active in their movements, and are at the same time noted for the singularity of their gait. This consists of a half-running and half-jumping action, induced by the peculiar structure of their feet and greater length of the hind legs, which are modified on a plan intermediate between that of the kangaroos and the dasyures, or native cats. The back of the animal while running being highly arched, adds to the grotesqueness of its appearance. Like the native cats, the pouch in the bandicoots opens backwards; it is furnished with eight teats, but not more than two young are usually produced at a birth.

The striped-backed bandicoot is not infrequently adopted as a household pet, in spite of its notorious garden depredations. When thus domesticated, it appears to be capable of developing a strong attachment for its owner. One that was owned by friends of the writer especially attached itself to the lady of the house. It was acquired when quite young, having escaped from the pouch of an adult female which the dogs had killed, and being then about the size of a mouse. It speedily learned to lap milk, and throve on a diet of bread and raw potato. As it grew larger it was allowed the run of the house, and also of the garden, but habitually returned to the sleeping-quarters selected by itself, and represented by the woolly depths of its mistress's work-basket. In this haven of rest it slept all day, scolding and snapping at any intruding hand. Towards dusk it would waken up and bustle about in a most energetic manner, with the air, in fact, of having an immense amount of business to transact within the very shortest limits of time. Its first dart was always towards a corner where a supper of bread-and-milk and potato was usually placed. This meal discussed, its evening's occupation commenced of scampering around the room and over every accessible article of furniture. Nor was it shy of climbing up and resting for a few seconds on the shoulders of its human friends, being always, however, in too great a hurry to prolong the visit. Finally, as with all pets, "Coota," as he was familiarly named, came to an untimely end--not a cat, however, on this occasion, but, if rumour whispers true, through over-indulgence in a too liberally furnished meal of custard pudding.

The flesh of this and other species of bandicoots is esteemed for food both by the natives and the white settlers in Australia. It is noteworthy of the banded variety, more especially, that the skin adheres so tightly to the flesh that its removal is a matter of some considerable difficulty. When full grown, this species measures as much as 18 inches in total length, and is little inferior to a rabbit with regard to the amount of good meat it provides for the larder.

THE POUCHED MOLE.

A still more essentially insectivorous marsupial is represented by the little mammal discovered only a few years since in the wild sandy wastes of Central Australia. In form and habits it so nearly resembles the familiar European mole that the title of the POUCHED MOLE has been very suitably given to it. At the same time, with regard to its remarkable organisation, it constitutes the sole representative of its peculiar family group. The first suspicions of the existence of this singular little animal were raised by the observation of peculiar sinuous three-lined tracks at irregular intervals on the surface of the sandy regions it inhabits.

After a long quest, with the aid of the aborigines, the first specimen was discovered reposing under a tuft of coarse porcupine-grass. A further investigation elicited the fact that its burrowing proclivities were much less pronounced than those of the ordinary moles, the little creature progressing alternately over the surface of the sand, and then ploughing its way, for several feet or yards, two or three inches only beneath the surface. All efforts to preserve examples of this marsupial alive for longer periods than three or four days proved abortive; for though the remains of ants and other insects were found within its viscera, it refused to feed upon the living supplies that were provided for it. In fact, the animal itself apparently ran the greater risk of being eaten.

The colour of the pouched mole is for the most part light fawn, varying in parts to golden yellow. One of its most conspicuous features, as illustrated in the accompanying photographs, is the abnormal size of the third and fourth toes of the fore limbs, their peculiar scoop-like character proving of eminent service to the animal in its customary sand-burrowing habits.

THE TASMANIAN WOLF.

The remaining family of the Australian marsupials constitutes a parallel to the carnivorous order of the higher mammalia, all its members being more or less flesh-eaters, and having their dentition modified with relation to such habits. One of these (the TASMANIAN WOLF, or TIGER of the colonists, better known to zoologists as the THYLACINE) is an animal of considerable size. Its dimensions equal those of a wolf or mastiff, with which the contour of its body and more especially that of the head very nearly correspond. In common with the true dogs, the thylacine hunts its prey by scent. This is well attested to by the following incident, as related by eye-witnesses. While camping out among the hills in Tasmania their attention was attracted very early one morning by a brush-kangaroo hopping past their fire in an evidently highly excited state. Some ten minutes later up cantered a she thylacine with her nose down exactly on the track, evidently following the scent, and in another quarter of an hour her two cubs came by also in the precise track. While not very swift, the Tasmanian "tigers" possess immense staying power, and will keep up a long, steady canter for many hours on end. Accustomed in its primitive state to run down and prey upon the kangaroos, wallabies, and other weaker marsupial mammals indigenous to the regions it inhabits, the Tasmanian wolf speedily acquired a predilection for the imported flocks of the settlers, and proved almost as destructive to them as its Old World namesake. To check its ravages, a price was put upon its head by the Tasmanian Government; and this measure, in conjunction with the rapid advances towards the complete settlement of the country which have been accomplished within later years, has compassed this animal's extermination in all but the wildest and most inaccessible mountain districts. The colour-markings of this animal are somewhat striking, the grey-brown tints which characterise the ground-hues of the body and limbs being varied by a series of dark bands traversing the buttocks, these being widest in this region, and continued forwards to the middle of the back. A somewhat similar cross-stripe pattern of ornamentation occurs in the relatively small member of the same family described later on as the Banded Ant-eater.

Examples of the Tasmanian wolf have frequently been on view at the Regent's Park Gardens, a very fine young male specimen being at present located in the marsupial section. Within a few weeks of its arrival it was on excellent terms with its keeper, though, owing to its somewhat imperfect sense of vision during the daytime, it was apt to snap somewhat promiscuously at those attempting to cultivate its close acquaintanceship. That a bite from its formidable teeth is not to be lightly risked will be made abundantly apparent by a glance at the successful yawning pose photograph secured of this example by Mr. Medland, and here reproduced. Although the thylacine is at the present time entirely limited in its distribution to Tasmania, it occurs in the fossil state on the Australian mainland; while, singularly to relate, the remains of a closely allied form have within recent years been unearthed in Patagonia. This circumstance, taken in conjunction with the fact that many other fossil types with Australian and New Zealand affinities have been discovered in the same South American strata, has strengthened the supposition maintained by many zoologists that in bygone ages a vast Antarctic continent, spreading through the areas now occupied by the Southern Indian and Pacific Oceans, temporarily united the now distinct lands of South America and Australasia.

THE TASMANIAN DEVIL.

Next in size to the thylacine, but possessing a more unenviable notoriety for the uncompromising sulkiness and savagery of its disposition, is the animal which, in virtue of the aforesaid qualities, is known by the title of the TASMANIAN DEVIL. In shape and dimensions this marsupial carnivore somewhat resembles a badger; but the head is abnormally large, the masseter muscles which control the action of the powerful jaws monopolising a very considerable share of the face area. The limbs are short and also very powerful, the front paws being well adapted to its burrowing habits. There is some slight variation in the colours of this marsupial Apollyon; and, as the aphorism runs concerning his sable namesake, he is not always so black as he is painted. More or less or in fact mostly black he always is, but there is usually a redeeming thread or patch of white upon his coat. This may take the form of a small star-like spot only on the front of its chest, which not infrequently extends to a narrow crescent-shaped band or line continued round the neck almost to the shoulders. One or more supplementary spots of white may also be developed upon the flanks and hindquarters.

The destructive propensities of the Tasmanian devil, wherein the farmers' sheep and poultry are concerned, are in no way inferior to those of the Tasmanian wolf, and in consequence of their former much greater abundance the havoc these animals committed was the more serious. Placed, like the last-named type, under Government ban, these native devils have, in comparison with the earlier days of colonisation, very considerably ceased from troubling, and with the ever-progressing march of settlement and civilisation will probably be altogether exterminated at a no very distant date. A bag of no less than 150 of these marauders, in the course of one winter, was recorded from an upland sheep-station some twenty or thirty years ago. In common with the thylacine, it has been observed that the Tasmanian devil has a marked predilection for prowling along the seashore in search apparently of crabs, fish, or any acceptable flotsam and jetsam that may be cast up by the waves.

Examples of this most unamiable of mammals were brought in alive on several occasions to the Hobart Museum during the writer's residence in Tasmania, but in all cases obstinately resisted every attempt towards the establishment of a friendly footing. Their ultimate relegation to the specimen-cases was, under the circumstances, unattended by any very poignant manifestations of regret. A fact brought into prominent notice during subsequent post-mortem investigations was the extraordinary extent to which these animals are infested with vermin. Possibly this circumstance is to a considerable extent accountable for the creature's unconquerable irritability. The experiment as to whether a course of disinfecting treatment, by baths or otherwise, would not conduce towards the taming of this native devil, where all other applied methods have failed, would at all events be worth the trial. The bath pure and simple is a wonderful soporific for unruly tempers. As most schoolboys know, a pail of water, from which the patient is withdrawn when a watery grave is apparently inevitable, is an unfailing specific for the taming of mice and other "small deer." The writer's experience with a villainously savage cat which one night fell incontinently into an uncovered cistern, and was rescued by him at almost the last gasp, will not be readily forgotten. That cat, though still a vixen to the ordinary members of the household, forthwith attached itself affectionately to its rescuer, and would sit for hours awaiting his arrival on the doorstep when the business of the day was over. Other fierce creatures, including the Tasmanian devil, would possibly prove amenable to the judicious application of the "water cure."

THE NATIVE CATS.

The animals common in Tasmania and throughout the greater portion of the Australian Continent, and familiarly known as SPOTTED or NATIVE CATS, and to zoologists as DASYURES, enjoy also an unenviable reputation for their depredations among the settlers' hen-roosts. To look at, these native cats are the most mild-mannered and inoffensive of creatures. Actually, however, they possess the most bloodthirsty proclivities, and may be aptly compared in their habits to the stoats, weasels, polecats, and other Old World carnivora. There are some five known species, the largest being equal to an ordinary cat in size, and the smaller ones about half these dimensions. All of them are distinguished by their spotted pattern of ornamentation, such spots being white or nearly so, and more or less abundantly sprinkled over a darker background which varies from light grey to chocolate-brown. In the commonest form, represented in the accompanying photograph, the ears and the under surface of the body are also often white. No two individuals, however, are to be found precisely alike in the pattern of their markings. The dasyures differ from the two preceding types, the Tasmanian wolf and the devil, in being essentially arboreal in their habits, living by day and breeding, as the majority of the Australian opossums, in the hollow gum-tree trunks, from which they emerge at nightfall to seek their food. This, in their native state, when hen-roosts are not accessible, consists mainly of birds and such smaller marsupial forms as they can readily overpower.

THE POUCHED MICE.

The so-called POUCHED MICE represent a group of smaller-sized carnivorous mammals which have much in common with the dasyures, but are devoid of their spotted ornamentation. None of them exceed a rat in size. They number about twelve or fourteen known species, and are distributed throughout the greater part of Australia and New Guinea, and extend thence to the Aru Islands. They are said not to occur in the extreme north of the Australian Continent. The writer, however, obtained an example of the brush-tailed species, here illustrated, from the neighbourhood of Broome, in the farthest north or Kimberley district of Western Australia. This specimen, which was caught alive in a rat-trap, exhibited astonishingly potent gnawing powers, almost succeeding one night in eating its way through the wooden box in which it was temporarily confined. The habits of this species are omnivorous, and chiefly akin to those of the ordinary rats, it being accustomed to prowl round the out-buildings at night, picking up any unconsidered trifles in the way of food that may be left unprotected.

Many of the smaller members of this tribe are no larger than mice; and in one form, known as the JERBOA POUCHED MOUSE, inhabiting Queensland and New South Wales, the hind limbs are abnormally prolonged, and the animal progresses by leaps and bounds, after the fashion of the true jerboas, or its nearer relatives, the ordinary kangaroos and rat-kangaroos.

THE BANDED ANT-EATER.

One of the most interesting from the zoologist's standpoint, and the last on our list of the Australian marsupials, is the little creature, limited in its habitat to Western Australia, locally known as the SQUIRREL. The BANDED ANT-EATER, with reference to its striped ornamentation and ant-eating habits, is the name by which it is usually chronicled in natural history works. In size and shape, except for its more pointed snout, its squirrel-like aspect is certainly somewhat striking. Like the true ant-eaters of the Edentate Mammalian Order, it, however, possesses a long protrusile tongue, with which it is accustomed in a similar manner to lick up the ants which constitute its main food-supply.

The most interesting biological peculiarity of this animal is the abnormal development of its teeth. These number as many as from fifty-two to fifty-six, and exceed the dental formula of any other known existing marsupial. The usual colour of this interesting little animal is a warm chestnut-brown, banded transversely over the back with white, these stripes being widest and most conspicuous over the hindquarters. This somewhat paradoxical marsupial possesses no pouch, the young, when first born and attached to the nipples in the manner characteristic of ordinary marsupials, being covered over and concealed among the longer hairs that clothe the abdominal region. In the dasyures, or native cats, previously described, the pouch exists only in a rudimentary condition, its function being fulfilled by merely a few skin-folds; while in the "tiger" and native devil the pouch, contrary to that of the kangaroos, opens backwards.

In disposition the banded ant-eater presents a marked contrast to that of many of the preceding types. Caught in its native habitat, it does not attempt to bite, and soon becomes reconciled to captivity. The peculiar nature of its diet, however, militates against its being easily transported over-sea from the Antipodes.

THE AMERICAN OPOSSUMS.

The little group of the American marsupials contains some three or four generically distinct types whose relationship with the Australian members of the order is in the direction of the dasyures and bandicoots rather than with the kangaroos and phalangers. Included in one family, they are popularly known as Opossums, but differ among themselves very considerably both in aspect and habits. The most remarkable among them is undoubtedly the so-called YAPOCK, or WATER-OPOSSUM, an inhabitant of South America, and ranging in its distribution from Guatemala to Brazil. In both form and habits this animal so closely resembles an otter that it was referred by the earlier naturalists to the Otter Tribe. It tunnels holes in the banks of the rivers it frequents, and feeds entirely upon fish, crustacea, and aquatic insects. The feet, and more especially the hind ones, are distinctly webbed; the tail is naked, scaly, and non-prehensile; and the fur is short and thick, as in the ordinary otters. The ground-tint of the fur is a light grey: this is diversified by a black or dark brown stripe that runs down the centre of the back, and expands over the shoulders, loins, and hindquarters into saddle-shaped patches or bands of the same dark hue.

The COMMON or VIRGINIAN OPOSSUM, while the only representative of the Marsupial Order found in the temperate latitudes of the North American Continent, has a very considerable range of distribution, occurring in equal abundance throughout the tropical regions of South America. In these warmer latitudes it differs to such an extent in the character of its fur and other minor points that it was for some time regarded as a distinct species, and was distinguished by the title of the CRAB-EATING OPOSSUM. Biologists are, however, now agreed that the supposed species is only a local variety. As a matter of fact, a very considerable amount of variation in the colour and markings is found to exist among the individuals of the most familiarly known northern race. In form the animal may be suitably compared to a huge rat, nearly equalling a cat in size, with an abnormally large head and pointed snout. The tail is long, almost naked for the greater portion of its length, and pre-eminently prehensile. The fur is of a mixed character, consisting of an undergrowth of a fine, close, woolly texture, through which protrudes a less dense series of long bristle-like hairs. The colour of the fur ranges from black to white, and includes all varieties of intermixture. The face, more especially in the northern race, is usually much the lightest or altogether white, while in the tropical South American examples it is more often darker, or it may be completely black.

The opossum, like the rat, is an omnivorous feeder; and being of so much larger size, and possessing an insatiable appetite, constitutes itself a veritable pest to the fruit-grower, the agriculturist, and the poultry-farmer. In effecting its entrance to hen-roosts or other food-yielding enclosures, it exhibits an amount of cunning and pertinacity possessed by no other mammal. Caught red-handed in these depredations, it has recourse to stratagems which have won for it a reputation that has long since passed into a household word. Feigning death, or "playing 'possum," is a game at which it is well known to be a past-master, but by which it still frequently succeeds in hoodwinking the unwary, and so saves its skin. Discovered thieving, and receiving perhaps a haphazard but by no means disabling blow, it at once collapses, and with film-covered eyes and protruding tongue is to all intents and purposes dead. It may be kicked round the premises, and finally probably taken up by the tail and flung ignominiously outside, without betraying vitality by even so much as a wink. But no sooner is the coast thoroughly clear of the avenger than the stiffened limbs relax, the eyes reopen, and Brer 'Possum trots off, as fresh as ever. Maybe it is the ripening maize or the persimmon-patch that next engages his attention, and in either case he walks in and feeds right royally, laying up a goodly store of fat against the approaching winter months of scarcity.

Away from human habitations the opossum is an essentially arboreal animal, living and breeding for the most part, like his Australian cousins, in hollow trees, and making excursions therefrom in all directions in quest of food. His much-mixed natural diet may consist of tender shoots and leaves, and the wild grapes and the many other berries and fruits the forest produces. He craves, however, after a due admixture of animal pabulum, and birds and their eggs, insects, lizards, and the smaller mammals furnish their quota to his menu. Crustacea, such as crabs and the crayfish which abound in the American streams and marshes, have an irresistible attraction for him; and it is on this account that, in the southern area of his distribution, where these crustacea are so plentiful as to constitute his main diet, and his face is browned by the more glowing sun, he is known by the title of the Crab-eater.

Although fattening up against the winter, he, even in his most northern limits, does not hibernate, but may even be seen leisurely picking his way over the snow, probably tracking some unfortunate squirrel to its lair, which in due time is located, dragged out, and devoured. While assimilating his meal of flesh or fruit, Brer 'Possum likes to have all four hands at liberty, his hind feet being also graspers; and so he twists his tail round a convenient branch, and, hanging _perdu_, leisurely enjoys his feast. The opossum, like the rat--to which it has in aspect and many of its habits been likened--is a most prolific breeder, as many as from six to sixteen young being comprised in the litter. When born, they are immediately transferred to the somewhat capacious pouch, and remain there without venturing outside until they are about the size of an ordinary mouse.

A third and very distinct type of American opossums is the one represented on page 380, which, from its mouse-like size and aspect, is commonly known as the MURINE OPOSSUM. The most distinct feature of this little animal is that, though a genuine marsupial, it has no pouch, but carries its young on its back, the little creatures twining their tails round that of their mother, and so securing a stable anchorage. Although thus loaded up and transformed for the time being into a sort of combination perambulator and feeding-flask, the happy but anxious parent pursues the even tenor of her way among the tree-branches and thicket-growths with almost unabated agility. This species, in common with MERIAM'S OPOSSUM and the WOOLLY OPOSSUM and several others which carry their young, to as many as a dozen in number, on their backs, are denizens of tropical South America. One of these, named the PHILANDER OPOSSUM, attains to the somewhat larger size of about 2 feet in total length, the long prehensile tail representing, however, the greater moiety of these dimensions.

THE SELVA.

South America has one other marsupial--the SELVA--an animal which, while possessing the dimensions and much of the aspect of an ordinary rat, is remarkable as differing so materially in the character of its teeth and other structural points that it cannot be referred to any existing marsupial family. On the other hand, this type is found to coincide in the above particulars with species hitherto only known in the fossil state, and excavated from the same tertiary deposits in Patagonia which have been productive of the distant ally of the Tasmanian wolf. It is yet hoped by zoologists that the discovery of other interesting and possibly some supposed extinct mammals may reward the thorough exploration of the vast South American forests. The capture in the flesh of some form allied to the huge ground-sloths, such as the Mylodon and Megatherium, is, however, now considered to be quite beyond the pale of possibility.

MONOTREMES, OR EGG-LAYING MAMMALS.

With this group or order of the Mammalian Class we arrive, as it were, on the borderland between the mere typical Mammals and Reptiles. In the last group, that of the Marsupials, it was observed that the young were brought into the world at an abnormally early and helpless phase of their existence, and usually consigned, until able to see and walk, to a variously modified protective pouch. With the Monotremes a yet lower rung in the evolutional ladder is reached, and we find that the young are brought into the outer world as eggs, these being in the one case deposited in a nest or burrow, and in the other carried about by the parent in a rudimentary sort of pouch until they are hatched.

The living representatives of this singular mammalian order are but few in number, being restricted, in point of fact, to only two distinctly differentiated family types--the Echidna or Porcupine Ant-eater, and the Platypus. These monotremes, moreover, like the majority of the existing marsupials, are limited in their distribution to the Australasian region. The single species of the Platypus is only found in Tasmania and the southern and eastern districts of the Australian Continent, while the Echidna numbers some three recognised species, two of which belong to Australia and Tasmania and the third to New Guinea.

THE ECHIDNA.

The ECHIDNA, PORCUPINE ANT-EATER, or "PORCUPINE," as it is commonly called by the Australian colonists, would seem at first sight to represent an animal in which the characters of the hedgehog and the common porcupine are interblended, the innumerable spines being longer than those of the former, but less in length than those of the last-named animal. The head, with no externally visible ears and remarkable elongated beak-like snout, however, at once proclaims it to be altogether distinct from these. The animal has no teeth, and the tiny mouth at the termination of the beak-like snout simply constitutes an aperture for the extrusion of the worm-like glutinous tongue, wherewith, after the manner of the true ant-eaters, it licks up the inhabitants of the ants' nests upon which it feeds. For tearing down the ants' nests and obtaining its customary food, as also for its inveterate burrowing propensity, the feet, and more especially the front ones, are provided with strong, blunt, and very powerful claws. The male animal is in addition armed on the hind feet with a peculiar supplementary spur, which is, however, still more conspicuously developed in the platypus.

Three distinct species of the echidna are recognised by zoologists. The one peculiar to the cooler climate of Tasmania is remarkable for its more slender spines, the much greater abundance of the long bristle-like hairs, and the thickness of the seal-brown under-fur, as compared with the typical Australian form. In North-west New Guinea the largest and most aberrant form is met with. Normally it has only three toes in place of five to each foot, the spines are very long and thick, the body is deeper and more compressed, and the animal stands comparatively high upon its feet.

The writer, during his residence in Tasmania, had several examples of the local species as domestic pets. For the first few days they were very shy and untractable, burrowing into the earth and seeking to escape, or presenting an impenetrable _cheval de frise_ of sharp-pointed spines to the hands that sought to caress them. After a short interval, however, the creatures became entirely reconciled to human society and the small amount of restraint to which they were subjected. They would follow their owner about the garden, or, flattening their bodies and spreading out their limbs to the greatest extent, lie basking in the sun close to where he might be seated. They also apparently appreciated being carried, slung across their owner's arm after the manner of a lap-dog. Living in the near vicinity of unreclaimed bush-land, it was found possible to keep these echidnas well supplied with their customary food; they were, in fact, permitted to forage on their own account. Liberated amidst their normal surroundings, they would walk leisurely from one ant-hill to another, tearing down the side of it with their powerful front claws, and appropriating its living contents with the greatest relish. It was observed, however, in this connection that the echidna paid attention entirely to the succulent white larvæ and pupal phases of the insects with which the inner chambers of the ant-hills are customarily crowded, and that adult ants, as they abounded in the tracts near at hand or elsewhere, were altogether neglected. In addition to this natural food these animals were supplied daily with a saucer of either well-softened bread or porridge and milk, for which they evinced a decided appreciation, assimilating this food dexterously, though somewhat slowly, with the aid of their long protrusile tongues. Allowed to wander about the house, they displayed a most inquisitive turn of mind, peering into every crevice, and climbing upon every accessible article of furniture.

The echidna usually produces only one egg at a time; it is relatively small, not larger than a sparrow's egg, but equally and obtusely rounded at both extremities, and with a white leathery shell like that of a reptile. For some time previous to hatching, this egg is carried in a skin-fold or rudimentary pouch in the parent's abdomen, much similar to that possessed by many of the marsupials. The young one is also retained in this pouch for some weeks after escaping from the egg. When finally leaving the pouch, it is between three and four inches in length, and the spines are in an altogether rudimentary condition.

Examples of the Australian echidna have on several occasions been "in residence" at the Zoo; while the Hon. Walter Rothschild has been fortunate in keeping living specimens of both this and the very rare three-toed New Guinea variety in his admirably appointed menagerie at Tring.

THE PLATYPUS.

The egg-laying mammal known as the DUCK-BILLED PLATYPUS differs very essentially from the echidna both in aspect and habits. It is adapted especially for an amphibious life, and for feeding on molluscs, worms, and insects, which it abstracts from the muddy bed or banks of the rivers that it frequents. The somewhat depressed ovate body is covered with short dense fur much resembling in colour and texture that of an otter. The tail is short and flattened like that of a beaver, but in place of being naked and scaly, as in that animal, is covered, on the upper surface more particularly, with long, coarse, bristle-like hairs that intercross one another in all directions. Neither is this tail used, as with the beaver, as a mason's trowel, it being simply subservient as a steer-oar. The feet are all four distinctly webbed, the membranes of the front feet in particular projecting to some distance beyond the extremities of the claws, and so communicating to these members a singular resemblance to the feet of a duck. The head of the platypus tapers off from the body without any conspicuous neck, and terminates in a most remarkable duck-like beak, having at its base a supplementary membranous ferrule-like structure which would seem to serve the purpose of limiting the distance into which the beak of the animal is thrust into the mud during the quest for its accustomed food, and at the same time protecting the creature's eyes. The mouth of the adult platypus contains no teeth, simply a few horny plates; but, singularly to relate, rudimentary teeth exist temporarily in the young animals. These provisional teeth, moreover, correspond in a marked manner with those of some ancient types of mammals which occur as fossils in the tertiary deposits of North America. The platypus, with relation to the obliteration of its teeth in the adult state, is regarded as a very exceptionally modified form and not as the immediate prototype of the ordinary mammals.

The platypus is found in Tasmania and in the south and eastern districts of Australia only, being altogether unknown in the west and north. Being especially shy and retiring, and to a large extent nocturnal in its habits, it is not frequently seen even in districts where it may be rather abundant. The animal excavates burrows of so great a length as from thirty to fifty feet in the river-banks that it frequents, and at the extreme end of these burrows it constructs a loose nest of weeds and root-fibres, which it uses as its retreat, and also for the production of its eggs and young. There are invariably two entrances to these burrows, the one being under water, and the other usually opening into a tangle of brushwood at some little distance from the water's edge. As many as from one to four eggs and young may be produced at a time, but two is the more general number. From the first it would appear that the eggs and young are deposited and nursed in the nest, not being retained or carried about in a pouch, as observed of the echidna.

The late Dr. George Bennett, of Sydney, New South Wales, has probably placed on record the most detailed account of the ways and life-habits of these remarkable animals, though it did not fall to him to solve the much-vexed question as to whether or not they were oviparous. This discovery, as applied also to the like phenomenon in the case of the echidna, was the outcome within quite recent years of the researches of Mr. Caldwell. After much indefatigable exploration, in which he was ably assisted by the natives, Dr. Bennett obtained from the extremity of an exceptionally long burrow a mother and pair of half-grown young. The young ones survived several weeks, and proved most droll and interesting pets. In playful habits they much resembled puppies, chasing and rolling one another over, and pretending to bite with their toothless bills. They were also much addicted to climbing every scalable article of furniture, including even a tall book-case, which they would negotiate by "swarming" up behind it as a sweep climbs a chimney, with their backs to the wall and their feet against the back of the book-case. The sleeping and waking hours that both these and other examples kept were observed to be very irregular; for while usually most lively and disposed to ramble after it grew dusk, they would at other times come out of their own accord in the daytime, or perhaps one would ramble about while the other slept. When going to sleep, they would roll themselves up in a perfect ball, the head, tail, and limbs being closely folded over the abdomen.

The food question appears to have presented almost insurmountable difficulties so far against the permanent acclimatisation of these interesting animals in any of our European zoological gardens. At the Melbourne Zoo some considerable success was obtained by fencing off a small pond abounding with insects and well-established water-plants for their reception, and in this instance they had also the advantage of being brought speedily and within a few hours of their capture to their new home. For their long voyage to Europe the provision of an adequate quantity of living insects or other aquatic organisms is a by no means easy task. They have, however, been known to thrive on broken-up river-mussels for the space of two or three weeks, and would probably have done so for a longer period. This material might easily be stored for their use on board ship.

An incident concerning the natural predilections of the platypus that fell within the writer's observation in Tasmania might also be utilised in their experimental transportation. At the trout- and salmon-rearing establishment on the river Plenty--of which the writer was at the time superintendent--the platypuses proved to be most destructive to the spawn both deposited in the hatching-boxes and upon the natural spawning-beds, or "redds," and they had in consequence to be systematically destroyed. This being the case, it is probable that they would be found to thrive well on a diet consisting to a large extent of the preserved roes or spawn of any easily procurable fish--such as the Murray perch and cod--and of which adequate supplies might with facility be stored aboard ship. The admixture in all cases of a certain amount of sand or mud with their provided pabulum would appear to be essential for digestive purposes, such material being always found in considerable quantities in their stomachs when dissected.

A distinguishing feature which the male platypus shares in common with the echidna is the peculiar spur developed on its hind foot. It is in this case, however, much larger and sharper, and has been accredited with aggressive functions and poisonous properties. There can be little doubt, however, that they are normally used by the animal only as clasping or retaining instruments during intercourse with the female at the breeding-season. At the same time, undoubted cases of persons receiving severe wounds from these animals' spurs have been placed on record. One such that fell within the writer's cognisance happened on the Murray River, on the Victorian and New South Wales boundary. A young fisher-lad, on taking up his nets, found a half-drowned platypus entangled in them, and, whilst disengaging it, it convulsively gripped his hand between the two spurs, the points penetrating deeply into the flesh on either side. The result was a festering wound that refused to heal for many months, and for such time entirely deprived the lad of his use of that hand.

The fur of the platypus, dressed so as to remove the outer and longer series of hairs, nearly resembles that of the fur-seal in both colour and texture, and as a rare local product is highly prized for the manufacture of carriage-rugs and other articles.

With the egg-laying Echidna and Platypus we terminate the Mammalian Series, and they pave the way to the typical egg-laying animals which follow.
