der. It has, however, about one-fourth more peculiar genera, divided 

 about equally, and mainly between Carnivores and Eodents, four only 

 being Antelopes, and one only (Chrysochloris) an Insectivore. Of the 

 twenty -four genera common also to the Indian Eegion, one- third are 

 Chiropters. The remaining genera are, with very few exceptions, such 

 as occur also in the Eastern Province, only three or four being common 

 to the Southern and Western Provinces that do not also occur in the 

 Eastern. 



Of the eighty-two genera below enumerated as occurring in the 

 Southern Province, a considerable portion are restricted to its southern 

 half, while many others extend only over its northern portions. A few 

 others, white mainly restricted to this region, and eminently character- 

 istic of it, also extend somewhat into the Eastern Province. 



Genera of the South African Province. 



The Western Province. As already stated, the Western Province 

 differs greatly in respect to its physical characteristics from either of 

 the other provinces of the African Eegion, and has, in consequence, a 

 correspondingly specialized mammalian fanna. It resembles the In- 

 dian Eegion in its hot, damp climate and dense forests. And its fauna, 

 though distinguished by many peculier genera, is also, in respect to its 

 general fades, more like that of the Indian Eegion than is the fauna of 

 any other portion of the African Eegion. It is similarly rich in the 

 higher Quadrumanes and poor in Antelopes, while it shares with the
