are less curved than those of B. major), and approximate in 

 contour to those of B. Iclwel, from all the forms of which 

 this species is stated to present well-marked differences ; 

 general colour grey-roan, duller than in B. major and 

 approximating to the hues of Hippotragus equinus ; limbs 

 somewhat darker.

Genus DAMALISCUS (P. 32).

Elaine has shown that the western races, which inhabit 

 more or less arid districts, are characterised by the concave 

 facial profile, narrow muzzle, and long, much recurved, and 

 compressed horns; while the eastern forms, which mainly 

 frequent moist districts, have the profile more nearly 

 straight, the muzzle broader, the nasals longer, and the 

 horns shorter, less recurved, and cylindrical. The purple 

 bloom, which is absent in the typical race, appears in the 

 Northern Nigerian D. Jc. purpurcscens, and attains its fullest 

 development in the Juba race.

Typical locality Gribingi Valley, upper Shari district;. 



Type in Senckenberg Museum, Frankfurt-arn-Main. 



Differs from D. Jc. korrigum, of Lake Chad and lower 

 Shari districts, by the thinner horns, of which the tips are 

 strongly curved upwards and inwards, and the more slender 

 skull, which is markedly narrower across the orbits. From 

 D. k. tiany, which has a similarly narrow skull, this race 

 differs by the marked curvature of the horn-tips.
