304 On the East- African Reedbuck. 



A second name applicable to it is " Cervicapra? odroh^^ 

 Ilouglin ^^ based on an antelope observed by him on the 

 Kiver Set it. 



But if this antelope, with its widely expanded semilyrate 

 horns, is the true C hohor^ the question arises as to what is 

 the proper ap})ellation for the very different Reedbuck from 

 Il^ast Africa which has of late been known by that name. 



That animal, as is shown in the ' Book of Antelopes ' t> is 

 closely allied to the West- African Nagor {G. redunca, Pall.), 

 being distinguished from it merely by its greater size, the 

 difference there quoted being 9 inches as compared to 8 in 

 the basal length of the skull. 



A renewed comparison not only confirms tlie alliance of 

 the two forms, but shows that the difference is even less than 

 we then supposed ; for Messrs. Ward, who had already helped 

 so materially in this matter, have lent me the skull of an 

 unusually fine Nagor which had been shot by Lieut. A. A. E. 

 Ellison, K.N., IGO miles up the River Gambia, and this skull 

 measured no less than 8"65 inches (220 millim.) in basal 

 length, nearly as much as in ordinary East- African Reed- 

 bucks. The fur, at least of the head, is closer and finer than 

 that of East-x\frican specimens, but is quite similar in colour. 



These being the facts, it would appear better to treat the 

 Tohi as a subspecies of C. redunca, and in recognition of the 

 help received from Messrs. Ward I would suggest the name 



Cervicapra redunca Wardi, subsp. n. 



Size rather larger than in the typical subspecies, basal 

 length of skull 9 inches or more. Hair coarser and shaggier. 

 Colour similar. 



Skull of the type (an old male) : — 



Basal length 234 millim. (9"2 inches) ; greatest breadth 

 114 (4*48) ; muzzle to orbit 138 (5'45). Horns : length round 

 curve in front 235 (9'25), circumference at base 146 (5"75), 

 breadth across most distant points externally 190 (7 '5), tip 

 to tip 143 (5-6).
