GRANT'S GAZELLE. 



105 



rump white; the white of the rump extending forwards in an angle 

 into the darker colour of the body ; knee-brushes of moderate 

 length, grizzled ; horns of great length in both sexes, much com- 

 pressed from side to side, marked by strong annulations which 

 completely surround the horn for the proximal half of its length, 

 but become obsolete on the posterior surface of its distal or upper 

 half. The horns diverge at first gradually, then more boldly, their 

 tips converging and giving to the set of the horns a remarkably 

 perfect lyrate form. 



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 G. soemmerringi, mohr, and 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 definite black pygal band, which is only shown in 

 very young specimens of G. soemmerringi, is absent entirely in 

 G. dama, and only indefinitely shown in G. mohr. In the watered- 

 silk mottling of the neck and back Gazella granti differs from all 

 other known Gazelles. 



Habitat East Africa.
