the last, but there are two horns, and the skin is smoother, with 

 no fold crossing in front of the shoulder. Although variable in 

 this respect, this species is the most hairy of all the Rhinoceroses, 

 as it is the smallest. Its range extends from the Bengal Sandar- 

 bans to Sumatra, and there are several local races ; the two 

 specimens exhibited belonging to the dark-coloured Malay race. 



African -Africa is the home of two species of Rhinoceros, in 

 Rhinoceroses k° tn °^ wmcn there are no distinct folds in the 

 skin ; teeth are absent from the front of the jaws of 

 the adult, there are two large horns placed close together, and the 

 nasal bones of the skull are blunt and rounded. Of the two 

 species, the larger is the White Rhinoceros, also known as BurchelFs 

 or the Square-mouthed Rhinoceros {Rhinoceros [Diceros] simus, 

 1 002, fig. 3 a), formerly numerous in the districts to the north of the 

 Orange River, but now nearly exterminated, although existing in 

 [Case 37.] Central Equatorial Africa near Lado. The most distinctive external 

 features of this species are the short and truncated muzzle, and non- 

 prehensile upper lip ; but it is also well characterised by the very 

 complex pattern of the grinding-surface of the upper molar teeth, 

 which become worn quite flat. Its food consists solely of grass. 

 [CaseH.] In the Common, or Black, Rhinoceros (R. [Diceros] bicornis, 1003, 

 fig. 3 b) the upper lip is distinctly prehensile, and the upper 

 molar teeth are of a simpler type, their grinding-surfaces being 

 ridged. This species feeds entirely on leaves and twigs. There is 

 great variation in respect to the relative lengths of the two horns; 

 those individuais in which the second is as long as or longer than 

 the first have received the name of Keitloa.

 dactyla, modern Equidce are distinguished by the tall crowns and 

 complex structure of their cheek-teeth, in which all the hollows 

 and valleys formed by the infoldings of enamel are filled by 

 cement, so as to form a grinding surface of a perfect type. 

 Another feature is the presence of an infolding of the enamel in 

 the summits of the incisors, thus producing what is called the
