THE FLAT-NOSED RHINOCEROS. 187 



nearly double that of the specimen named Rhino- 

 ceros bicornis. These two animals are recognized by 

 the negroes and Hottentots, as two very distinct 

 species, and are distinguished by them by different 

 names. As we have killed ten examples, I have 

 had sufficient opportunities of observing the cha- 

 racters which distinguish them. They consist 

 principally in the form of the mouth, as may be 

 verified by comparing the Rhinoceros bicornis and 

 the Rhinoceros unicornis with the figure, (PL XIII.) 

 which I have carefully drawn after nature. I 

 have named this species Rhinoceros simus. The 

 negroes and Hottentots inform me, that it eats 

 nothing but grass, while the other species feeds 

 on branches of trees and shrubs, a peculiarity 

 which may be inferred from the structure of the 

 mouth. The head, when separated from the first 

 vertebrae, was of such enormous weight, that four 

 men could only raise it from the ground, and eight 

 were required to put it into the carriage. The 

 flesh of the two species is equally good to eat ; 

 and they resemble each other in having a double 

 horn, and wanting conspicuous hairs on the skin, 

 which distinguishes, at first sight, the Rhinoceros 

 unicornis. The following comparative measures, 

 taken from adult individuals, killed by ourselves, 

 in these countries, will afford a proof of the diffe- 

 rence of size :
