Typical locality near Speke Gulf, Victoria ISTyanza, in the 

 Usagara district of German East Africa. 



Distinguished from typical race by the strong outward 

 curvature and divergence of the horns, of which the tips 

 -are backwardly hooked. Good horns measure from 25 to

From Thomas, Proc. Zool. Soc. 1903. 



28 inches in length, with a tip-to-tip interval of from 18^ to 

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



Whether this so-called race is really anything more than 

 the product of a single origina;l 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 rohcrtsi 

 type.
