Typical locality swamps of the White Nile, about sixty 

 miles below Khartum. 



Type in Zoological Museum, Berlin. 



Size approximately the same as in thomasi. General 

 colour — in adult bucks — deep black ; a large patch round the 

 eyes and ears of each side, the whole of the backs of the 

 ears, the muzzle, chin, and upper part of throat, together 

 with chest and inner sides of upper portion of limbs, white ; 

 fronts of fore-legs and lower part of those of hind pair, with 

 the exception of a broad white hoof-band to each, blackish ; 

 horns relatively slender. Young males, and apparently 

 females at all ages, fulvous. Good horns measure from 21 to 

 22^ inches in length (in one case, if rightly determined, 24|), 

 with a girth of from 6 to 7^ inches, and a tip-to-tip interval 

 of from 6f to 15| inches. Whether some or all adult bucks 

 assume a seasonal fulvous phase is not known. 



The range embraces the swamps of the Upper Nile region, 

 inclusive of the Sobat.
