The male and female in the Frankfort Museum are smaller 

 than A. Gazella of the Cape, and both have the face-streaks se- 

 parate; 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. Ga- 

 zella.
