Typical locality near Speke Gulf, Victoria Xyanza, in the 

 Usagara district of German East Africa.

 •curvature and divergence of the horns, of which the tips 

 -are backwardly hooked. Good horns measure from 25 to 



Pig. is. — Skull and Horns of Usagara. Race of Grant's Gazelle 



{Gazella granti robertsi). 



From Thomas, Proc. Zool. Soc. 1903. 



28 inclies in length, with a tip-to-tip interval of from ISh to 

 28^ inches (in one instance 38^ inches). 



Whether this so-called race is really anything more than 

 the product of a single original herd may be doubtful, 

 as heads have come under the writer's observation in which 

 one horn was of the true granti, and the other of the robertsi 

 type.
