EXTERNAL FORM.--It would be quite impossible for any one to confuse any other quadrupedal animal with a mammal. The body of a reptile is, as it were, slung between its limbs, li...

The highest of mammals, the Primates,[404] may be thus differentiated from other groups:--Completely hairy, generally arboreal mammals, with five digits on fore- and hind-limbs,...

FIG. 138.--Bones of the Manus--A, of Pig (_Sus scrofa_). x 1/3. B, of Red Deer (_Cervus elaphus_). x 1/2. C, of Camel (_Camelus bactrianus_). x 1/8. _c_, Cuneiform; _l_, lunar;...

This order may be thus defined:--Small to large quadrupeds, terrestrial, arboreal, or aquatic, of usually carnivorous habits. The teeth have generally sharp and cutting edges, a...

Aquatic Mammalia of fish-like form; tail expanded into horizontal flukes; a fatty dorsal "fin" present in most species; anterior limbs converted into fin-like paddles; posterior...

Small to moderately large animals, furry, sometimes with spines. Toes with nails of a claw-like character, or sometimes approaching hoofs. Usually plantigrade, and only occasion...

The existing members of this order can be readily grouped into the Hyracoidea, Proboscidea, Perissodactyla, and Artiodactyla, each of which divisions has quite the value of an o...

The Marsupials may be thus defined:--Terrestrial, arboreal, or burrowing (rarely aquatic) mammals, with furry integuments; palate generally somewhat imperfectly ossified; jugal...

Terrestrial, partly subterranean, or arboreal creatures of quite small to gigantic size (some extinct genera), with frequently a covering of scales or bony scutes. Limbs clawed....

FIG. 121.--Bones of the manus A, of Tapir (_Tapirus indicus_). x 1/5. B, of Rhinoceros (_Rhinoceros sumatrensis_). x 1/5. C, of Horse (_Equus caballus_). x 1/8. _c_, Cuneiform;...

The Insectivora[378] are an order of mammals to which it is (to quote Professor Huxley) "exceedingly difficult to give a definition." They are, however, none of them large anima...

[1] The degeneration of the hind-limb in Whales and Sirenia forbids the use of this character as a distinctive one on the principles advocated by the selection of the above list...

This group includes the Seals, Sea-Lions, and Walruses,[316] all aquatic and, for the larger part, marine creatures. Being aquatic they have to some extent acquired a fish-like...

The animals that we considered in the last chapter, though showing certain unmistakable likenesses to the mammals, are nevertheless unquestionably not mammals but reptiles. In t...

Apart from those creatures whose fragmentary remains have been considered in the last chapter, and which belong to the earliest of mammaliferous strata, the remains of Mammalia...

DEFINITION.--Mammalia with teats. Mammary glands of sebaceous type. Heart with entirely membranous and complete right auriculo-ventricular valve. Brain generally with a corpus c...

The relationship of Mammals to Vertebrates lying below them in the scale, their origin in fact, is a much-debated question, with many attempted solutions. To enter into this lar...

The Mammalia form a group of vertebrated animals which roughly correspond with what are termed in popular language "quadrupeds," or with the still more vernacular terms of "beas...

Inasmuch as Sir W. H. Flower and Mr. Lydekker could not profess to treat the Mammalia exhaustively within the limits of nearly 800 pages, in their _Introduction to the Study of...
