X HAIRY-EARED RHINOCEROS 257 



by a much thicker coat of hairs, which are sometimes blacker 

 and sometimes redder. On account of its two horns it has 

 lieen proposed to separate it from the other Oriental species 

 into a distinct genus, Ccratorhinus. The animal has much 

 the same range as the last species, but extends to Borneo. 

 A variety of tliis species with hairy ears, from Assam, has been 

 separated as a distinct form, under the name of Bh. lasiotis, 

 by ]\Ir. Sclater. The animal upon which that species was 

 founded was until quite recently living in the Zoological Society's 

 Gardens. 



There are only two certainly-known species of Ehinoceros in 

 Africa. These are the White Ehinoceros {Bh. simus) and the 



Fig. 132. — Hairy-eared Rhinocercs. Rhinoceros lasiotis. ^ jV- 



Black Ehinoceros (FJi. hicornis). The origin of the names is not 

 easy to understand, since the " white " animal is, if anything, darker 

 in colour than the Black Ehinoceros. It is stated, however, that 

 in past years the specimens of Rh. simus found in the south-west 

 of Cape Colony were " paler and whiter in colour than those in 

 the north-east." At present there are no grounds for distinguish- 

 ing the species by their colour characters. But they are plainly 

 distinguishable on other grounds. Rhinoceros simus has a square 

 upper lip, and in relation to this crops the herbage upon the 

 ground. Rh. hicornis has a prehensile upper lip projecting beyond 

 the lower, and in a corresponding fashion feeds principally upon 

 the branches of shrubs. It has been pointed out by Mr.
