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. 
Rutnoceros, Lin. 
The species of this genus, in this particular, even 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 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 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 czecum extremely 
large. 
Rh. indicus, Cuv.; Buff. XI, vii. (The Rhinoceros of India.) 
Has, in addition toits twenty-eight grinders, two strong incisors 
in each jaw, two other small ones between the lower, 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. javanus, Cuv.; 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 the 
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 ofswhich, ‘besides being much more elongated than 
* that of any living ae ig is also ‘distinguished by a bony ver-
