 the white of the limbs. The hoofs also are stated to be longer than 

 in the typical race ; while it is suggested that there may be slight 

 differences in the horns. 



More distinct is the Kilimanjaro race (O. b. callotis], from British 

 East Africa south of the Tana river and the adjacent parts of German 

 East Africa. In this race the ears (which, as in all the members of
