The type-specimen of Bubalis cokei in the British Museum con- 

 sists of the dried head-skin and the skull, the latter without the 

 mandible or nasal bones. The whole top of the head in this scalp is 

 deep cinnamon-rufous, the cheeks and back of ears and neck tawny 

 and the throat tawny-ochraceous. The skull is somewhat immature, 

 the premolars having just errupted, the last one being not yet up to 

 the level of the general tooth-line. A part of the condyles, basi- 

 occipital and sphenoid region of the skull have been cut away. The 

 measurements of this skull are as follows : Condylo-basal length, 

 383 mm.; greatest length (bifurcation to premaxillse tip), 453; 

 zygomatic breadth, 123; length of upper tooth-row, 93; distance 

 from first premolar to tip of premaxillse, 131. 



Horns : Length on outside curve, 413 ; breadth at tip, 315 ; greatest 

 breadth, 395 ; circumference at base, 235. 



Among the Suahili this antelope is known as the kongoni, and the 

 term has become so familiar through its constant use by the negro 

 porters on safari that it has been adopted by sportsmen generally 

 for this species.
