and far down flanks. Underparts silvery grey, much 

 darkened by the slaty bases of the liairs. Ears dusky. Tail 

 dusky above ; its lower surface, together with the hands and 

 feet, dirty white. 



Skull very similar to that of E. g. suectcus in size and 

 general appearance; zygomatic arches slightly less expanded; 

 bullae slightly smaller and less inflated. Teeth normal; m^ 

 without a third re-entrant fold oti inner side in any of the 

 three specimens examined ; in E.g. suecieus, Miller ('Cata- 

 logue,' p. 31) found this fold to be present in about one-third 

 of the individuals.

Owing largely to its peculiar station and habits, the Kli[)- 

 springer, among African antelopes, shows quite a special 

 tendency to develop geographical and, in part, perhaps, merely 

 colonial races. The range of Oreotragus extends over the 

 whole of Africa south of the Sahara, from Northern Nigeria 

 and Somaliland to the Cape. Within this wide area, how- 

 ever, its distribution is markedly discontinuous, the animal 

 being restricted to the mountainous districts. Thus it is 

 absent from the great Congo forest region ; while, in the 

 more open country of East Africa, the lowlands intervening 

 between one " Inselberg " and another form, in all cases 

 w^here their breadth exceeds a few miles, decided barriers to 

 inter-colonial commutiication.
