the stomach is Bimple, and the ccecum ts large and complicated. It com- 

 prises the families of Rhinocerotidce, Tapirida, Hyracidte, and Equidce, 

 or the Rhinoceroses, Tapirs, Coneys and Horses. Their molars are six or 

 seven or each side, both above and below. 



Fam. Rhinooerotid2e.

Incisors persistent in both jaws in some, in others disappearing with age ; 



no canines ; molars tuberculate, the crown marked by narrow eminences, 



7 — 7 

 usually = — = ; feet with three hoofed toes ; one or two horns, placed one

Char. — Those of the family, of which it is the only genus. 



The animals composing this genus are large ungainly and unwieldy 

 looking, with long heads and a short tail, and the hide very thick with 

 several folds. The incisors vary somewhat both in number and in size, 

 and they are stated to bear an inverse ratio to the horns. Canines in a 

 rudimentary state exist in the mature foetus, but early disappear. The 

 molars are implanted by distinct roots. The crowns of the upper molars, 

 are subquadrate with two transverse eminences, joined by a crest to the outer 

 margin ; the crowns of the lower ones are longer, narrower, with two lunate 

 lines, having the convexity outwards. The nasal bones are very strong 

 and arched to support the horn, which is composed of longitudinal fibres, 

 as if of hairs closely compacted together without any bony structure. The 

 upper horn, when present, is fixed in the fi-ontal bone. The upper lip is 

 somewhat prolonged. The stomach is simple, and the cuecum large and 

 sacculated. The intestines are about eight times longer than the body, 

 and the villi are very large. The females have two inguinal mammse. 

 Rhinoceroses are found only in the tropical regions of the old world. 

 Three species occur in India and Malayana, two of which are found within 

 onr limits ; and four or five others inhabit Africa.
