each other in their grinders, having seven upper ones on each 

 side, with a square crown and various salient lines, and seven 

 lower ones, the crown of which forms a double crescent, and 

 the last of all a triple one ; but their incisors vary^ 



Rhinoceros, Lin. 



The species of this genus, in this particular, eveh vary among them- 

 selves. They are large animals ; each foot is divided into three 

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

 into a sort of arch, support a solid horn which adheres to the skin, 

 and is composed of a fibrous and horny substance, resembliilg ag- 

 glutinated hairs. They are naturally stupid and ferocious, frequent 

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

 stomach is simple, intestines very long, and the csecum extremely 

 large. 



Rh.indicus, Cuy.; Buff. XI, vii. (The Rhinoceros of India.) 

 Has, in addition to its twenty-eight grinders, two strong incisors 

 in each jaw, two other small ones between the lowei', and two 

 still smaller again outside of the upper ones. It 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 inhabits the East Indies, and chiefly be- 

 yond the Ganges. 



Rh.javantts, Cuv.j Fr. Cuv. Mammif. (The Rhinoceros of 

 Java.) With the large incisors and single horn of the preced- 

 ing, has not so many folds in the skin, though one of them on 

 the neck is larger ; but what is most remarkable, is, that thei 

 whole skin is covered with small compact angular tubercles. 

 It has hitherto been found in Java only. 



Rh. sumatrensis^ Cuv.; Bell. Philos. Trans. 1793; F. Cuv. 

 Mammif. (The Rhinoceros of Sumatra.) The same four 

 great incisors as the preceding, but there are scarcely any folds 

 of the skin, which moreover ' is hairy, and has a second horn 

 behind the first. 



Rh. africanus, Cuv.; Buff. Supp. VI, vi. (The Rhinoceros of: 

 Africa.) Furnished with two horns, like the preceding ; has no 

 fold of the skin, nor any incisor teeth, its molars occupying 

 nearly the whole length of the jaw. This deficiency of incisors 

 might warrant its separation from its congeners., 



There have been found, under ground, in Siberia, and in dif- 

 ferent parts of Germany, the bones of a two-horned Rhinoceros, 

 the cranium of which, besides being much rao^e-elongated than 

 that of any living species, is also distinguished by a bony ver-
