MAMMALIA. 



first place, three genera, very similar to each other in their grinders, but their 

 incisors vary. 



The species of this genus, in this particular, even vary among themselves. 

 They are large animals ; each foot is divided into three 

 toes ; and the bones of the nose, which are very thick 

 and moulded into a sort of arch, support a solid horn 

 which adheres to the skin, and is composed of a fibrous 

 and horny substance, resembling agglutinated hairs. 

 They are naturally stupid and ferocious, frequent 

 marshy places, and feed on herbs and branches of trees. 

 They are found in India, Java, Africa, and Sumatra. 



Rh. Indicus, Cuv. (The Rhinoceros of India.) Has 

 but one horn, and the skin is remarkable for the deep 

 folds into which it is thrown behind and across the 

 shoulders, and before and across the thighs. It has, in 

 addition to its twenty-eight grinders, two strong incisors in each jaw, two other 

 small ones between the lower, and two still smaller again outside the upper 

 one. It inhabits the East Indies, and chiefly beyond the Ganges. The 

 Rhinoceros of Java, (Rh. Javanus, Cuv.) differs from the Indian species, in 

 having fewer folds in the skin, and by having the whole skin covered with 

 small compact angular tubercles. It has hitherto only been found in Java. 



Rh. Africanus, Cuv. (The Rhinoceros of Africa.) Furnished with two 

 horns; has no fold of the skin, nor any incisor teeth, its molars occupying 

 nearly the whole length of the jaw. 



Various fossil species are found in Siberia, Tuscany, and different parts of 

 Germany. A body, nearly entire, was taken from the ice on the banks of 

 Vilhoui in Siberia, having two horns, and the cranium much more elongated 

 than in any living species, and having a bony vertical partition supporting the 

 bones of the nose, which must have been covered with tolerably thick hair. 

 Some of the bones, found in France, announce a body hardly larger than the hog. 



HYHAX, Herm. 



The Damans, as they are termed, have long been placed among the Rodentia, 

 on account of their small size ; if, however, we examine them closely, we shall 

 find, the horn excepted, that they are Rhinoceroses in miniature, at least they 

 have similar molars; but their upper jaw is furnished with two strong incisors 

 curved downwards, and at an early age with two very small canini ; the lower 

 one has four incisors, but no canini. 



PAL^IOTHEIUUM, Cuvier. 



This is also a lost genus, with the same grinders as the two preceding, six 

 incisors, and two canini in each jaw like the tapirs, with three visible toes 

 to each foot; they had also, like the tapirs, a short fleshy proboscis. We
