not one of the specimens which have come under my obsenation have 

 had any incHnation to assume that form : but as this is the only 

 Western- African species which in any way agrees with Buffou's figure, 

 perhaps it is best to adopt Mr. Ogilby's suggestion. The name of 

 Koba or Kob appears to be common to many species. Schui2 errone- 

 ously considers Damalis SenegaJeasis, Antilope adenota and A. for- 

 fex (H. Smith) as synonyms of this species. 



c. Nape with a linear, central, compressed, recurved mane.

The head of the female covered with the skin from Macarthy's 

 Island, on the coast of Gambia, which Mr. "MSTiitfield brought home, 

 did not appear to diflfer from the specimen from the Cape in the 

 British Museum. The species does not appear to be uncommon in 

 the locality, for Mr. \Miitfield brought over several pairs of horns. 

 He states the flesh is very good venison. " It is called Dacoi or 

 WTiite Mouth by the Mandlngoes, Kob and Koba by the Joliffs, 

 and Fache brune bv the French at Senegal." This is certainlv not 

 the Kob of Buffon (xii. t. 32. f. 1, 2). The negroes at the Gambia 

 declare that this animal never bears more than one fawn ; for after 

 that period, the horns increase in length, and enter the loins and 

 destroy the animals ! 



Buffon (xii. 271. t. 31. f. 6) figures the horn of this species, which 

 had been made into a powder-flask, under the name of Tzeiran. 



A. barbata of Daniels appears to be only a bad drawing of this 

 species. 



The variety is the size of the Common Stag, Cervus Elaphus.
