+he cheek-teeth have two simple transverse crests on their 
crowns, very different from the complex enamel foldinos of the 
teeth of E/hinoceroses and Horses, the nasal bones are small, 
and the toes four in number on the fore, and three on the hind 
feet. They are swamp-loving animals, excellent swimmers and 
divers ; one species occurring in Malaya and the others in

Rhinoceroses are characterized by the thickness and solidity 
of their bones, by the structure of their molar teeth, and the 
enlargement of their nasal bones to serve as supports for the 
single or double horns. Incisor teeth are wanting in the adults 
of the African species; but in the Indian there is a pair of large 
ones above, and two large and two small ones below. 
The Asiatic Two-horned Rhinoceros [Rhinoceros sumatrensis), 
a native of the Malay countries, is represented by a mounted 
specimen (toot ) and skulls. The African Black Rhinoceros 
(R. hicornis), with a wide range in Africa, is distinguished from
