BATS.
Of the bat kind there is an extraordinary variety: the churi-churi is the smallest species, called vulgarly burong tikus, or the mouse-bird; next to these is the kalalawar; then the kalambit; and the kaluwang (noctilio) is of considerable size; of these I have observed very large flights occasionally passing at a great height in the air, as if migrating from one country to another, and Captain Forrest notices their crossing the Straits of Sunda from Java Head to Mount Pugong; they are also seen hanging by hundreds upon trees. The flying-foxes and flying-squirrels (Lemur volans), which by means of a membrane extending from what may be termed the forelegs to those behind, are enabled to take short flights, are also not uncommon.
ALLIGATORS AND OTHER LIZARDS.
Alligators, buaya (Crocodilus biporcatus of Cuvier), abound in most of the rivers, grow to a large Size, and do much mischief.
The guana, or iguana, biawak (Lacerta iguana) is another animal of the lizard kind, about three or four feet in length, harmless, excepting to the poultry and young domestic cattle, and sometimes itself eaten as food. The bingkarong is next in size, has hard, dark scales on the back, and is often found under heaps of decayed timber; its bite venomous.
The koke, goke, or toke, as it is variously called, is a lizard, about ten or twelve inches long, frequenting old buildings, and making a very singular noise. Between this and the small house-lizard (chichak) are many gradations in size, chiefly of the grass-lizard kind, which is smooth and glossy. The former are in length from about four inches down to an inch or less, and are the largest reptiles that can walk in an inverted situation: one of these, of size sufficient to devour a cockroach, runs on the ceiling of a room, and in that situation seizes its prey with the utmost facility. This they seem to be enabled to do from the rugose structure of their feet, with which they adhere strongly to the smoothest surface. Sometimes however, on springing too eagerly at a fly, they lose their hold, and drop to the floor, on which occasions a circumstance occurs not undeserving of notice. The tail being frequently separated from the body by the shock (as it may be at any of the vertebrae by the slightest force, without loss of blood or evident pain to the animal, and sometimes, as it would seem, from the effect of fear alone) within a little time, like the mutilated claw of a lobster, begins to renew itself. They are produced from eggs about the size of the wren's, of which the female carries two at a time, one in the lower, and one in the upper part of the abdomen, on opposite sides; they are always cold to the touch, and yet the transparency of their bodies gives an opportunity of observing that their fluids have as brisk a circulation as those of warm-blooded animals: in none have I seen the peristaltic motion so obvious as in these. It may not be useless to mention that these phenomena were best observed at night when the lizard was on the outside of a pane of glass, with a candle on the inside. There is, I believe, no class of living creatures in which the gradations can be traced with such minuteness and regularity as in this; where, from the small animal just described, to the huge alligator or crocodile, a chain may be traced containing almost innumerable links, of which the remotest have a striking resemblance to each other, and seem, at first view, to differ only in bulk.
CHAMELEON.
The chameleon, gruning: these are about a foot and half long, including the tail; the colour, green with brown spots, as I had it preserved; when alive in the woods they are generally green, but not from the reflection of the leaves, as some have supposed. When first caught they usually turn brown, apparently the effect of fear or anger, as men become pale or red; but if undisturbed soon resume a deep green on the back, and a yellow green on the belly, the tail remaining brown. Along the spine, from the head to the middle of the back, little membranes stand up like the teeth of a saw. As others of the genus of lacerta they feed on flies and grasshoppers, which the large size of their mouths and peculiar structure of their bony tongues are well adapted for catching.
(PLATE 14a. n.2. THE KUBIN, Draco volans. Sinensis delt. A. Cardon sc. Published by W. Marsden, 1810.)
The flying lizard, kubin, or chachak terbang (Draco volans), is about eight inches in its extreme length, and the membranes which constitute the wings are about two or three inches in extent. These do not connect with the fore and hind legs, as in the bat tribe, but are supported by an elongation of the alternate ribs, as pointed out by my friend Mr. Everard Home. They have flapped ears, and a singular kind of pouch or alphorges, under the jaws. In other respects they much resemble the chameleon in appearance. They do not take distant flights, but merely from tree to tree, or from one bough to another. The natives take them by springs fastened to the stems.
FROGS. SNAKES.
With animals of the frog kind (kodok) the swamps everywhere teem; and their noise upon the approach of rain is tremendous. They furnish prey to the snakes, which are found here of all sizes and in great variety of species; the larger proportion harmless, but of some, and those generally small and dark-coloured, the bite is mortal. If the cobra capelo, or hooded snake, be a native of the island, as some assert, it must be extremely rare. The largest of the boa kind (ular sauh) that I had an opportunity of observing was no more than twelve feet long. This was killed in a hen-house where it was devouring the poultry. It is very surprising, but not less true, that snakes will swallow animals of twice or three times their own apparent circumference; having in their jaws or throat a compressive force that gradually and by great efforts reduces the prey to a convenient dimension. I have seen a small snake (ular sini) with the hinder legs of a frog sticking out of its mouth, each of them nearly equal to the smaller parts of its own body, which in the thickest did not exceed a man's little finger. The stories told of their swallowing deer, and even buffaloes, in Ceylon and Java, almost choke belief, but I cannot take upon me to pronounce them false; for if a snake of three inches diameter can gorge a fowl of six, one of thirty feet in length and proportionate bulk and strength might well be supposed capable of swallowing a beast of the size of a goat; and I have respectable authority for the fact that the fawn of a kijang or roe was cut out of the body of a very large snake killed at one of the southern settlements. The poisonous kinds are distinguished by the epithet of ular bisa, among which is the biludak or viper. The ular garang, or sea-snake, is coated entirely with scales, both on the belly and tail, not differing from those on the back, which are small and hexagonal; the colour is grey, with here and there shades of brown. The head and about one-third of the body from thence is the smallest part, and it increases in bulk towards the tail, which resembles that of the eel. It has not any dog-fangs.
TORTOISE.
The tortoise, kura-kura, and turtle, katong, are both found in these seas; the former valuable for its scales, and the latter as food; the landtortoise (Testudo graeca) is brought from the Seychelles Islands.
There is also an extensive variety of shellfish. The crayfish, udang laut (Cancer homarus or ecrevisse-de-mer), is as large as the lobster, but wants its biting claws. The small freshwater crayfish, the prawns and shrimps (all named udang, with distinctive epithets), are in great perfection.
The crab, kapiting and katam (cancer), is not equally fine, but exhibits many extraordinary varieties.
The kima, or gigantic cockle (chama), has been already mentioned.
The oysters, tiram, are by no means so good as those of Europe. The smaller kind are generally found adhering to the roots of the mangrove, in the wash of the tide.
The mussel, kupang (mytilus), rimis (donax), kapang (Teredo navalis), seaegg, bulu babi (echinus), bia papeda (nautilus), ruma gorita (argonauta), bia unam (murex), bia balang (cuprea), and many others may be added to the list. The beauty of the madrepores and corallines, of which the finest specimens are found in the recesses of the Bay of Tappanuli, is not to be surpassed in any country. Of these a superb collection is in the possession of Mr. John Griffiths, who has given, in
