426 Dr. A. Gunther on some East-African Antelopes. 



this supposition has been confirmed by Mr. J. Thomson 

 bringing a frontlet of the same type from his late expedition 

 to Mount Kenia and Victoria Nyanza. The animal killed by 

 Col. Coke was probably a female ; he preserved with the skull 

 the skin of the head, which shows that the upper parts were 

 of a reddish-brown colour, gradually passing into a light greyish 

 brown below. For this species I propose the name of Alce- 

 lapJfus Gohii.

 Alcelaphus Cokii. 



The horns diverge from their root so much as to form a 

 right angle with the longitudinal axis of the skull, their basal 

 portion being almost in the same plane with the forehead ; 

 their distal half forms again a right angle with the proximal 

 half, the points being directed straight backwards. The front 

 part of the horns is strongly ribbed longitudinally between 

 the annulations, which are rather close near the base, and 

 more widely placed and prominent at the bend of the horn 

 witli which the animal butts. The annulations are more or 

 less effaced on the posterior surface of the horns and disappear 

 altogether above the upper bend. 



Mr, Thomson's specimen was an adult buck, in which the 

 horns are somewhat stouter and their bend is more decidedly 

 directed forwards.
