 Length of horns 16 inches, girth 5 inches, tip-to-tip interval 23J' inches. 



by Colonel Gunthorpe, show that these two supposed races 

 are inseparable. In the writer's specimen the interval 

 between the horn-tips is only 6 J inches, whereas in specimens 

 from the Binder and Blue Nile valleys catalogued in the 

 sixth edition of Ward's Records of Big Game, this interval 

 ranges from 15 to 18 inches. 



The range extends from Kordofan, the White Nile, 

 and the Isle of Meroe to the east of Lado and western 

 Somaliland.
