The horns of the adult female shot by Capt. Speke and Col. Grant 

 in Ugogo measured 15 inches round the curve. 



Comparison with allied Species. 



Gazella granti belongs, as pointed out in my former description, 

 to the group of long-limbed large Gazelles which are distinguished 

 by the white of the rump projecting in an angle into the fawn-colour 

 of the back and sides (vide P. Z. S. 1873, p. 537, B'). The allied 

 species are 6?. scemmerringi, G. mohr, and G. dama. From all these 

 it differs in the very much greater size, and in the form of the horns. 

 It is also peculiar in the presence of the dark lateral band, which is 

 wanting in the three above-named species, and in the remarkably defi- 

 nite black pygal band, which is only shown in very young specimens 

 of Gazella scemmerringi, is absent entirely in Gazella dama, and only 

 indefinitely shown in Gazella mohr. In the watered-silk mottling 

 of the neck and back Gazella granti differs from all other known 

 Gazelles.
