There is a male and female in the Frankfort Museum; they are 
smaller than A. Gazella of the Cape, and both have the face-streaks 
separate : there is a black streak on the throat, as in A. Gazella, but 
no bunch, nor is there any in the Frankfort specimen of A. Gazella : 
the mane of the nape of the male is small, indistinct, continued behind 
in a broader dark streak to the middle of the loins. In the male the 
mane is blackish, in the female like the back. They have no dark 
mark on the rump, found in A. Gazella.
