In Denham and Clapperton’s Travels I regarded this species as the 
Koba of Buffon, and H. Smith and Dr. Sundevall are of the same 
opinion: but on comparing the six pairs of horns of this species 
which I haye been able to examine with Buffon’s figure and descrip- 
tions, I find them all longer and much thicker at the base than But- 
fon describes them; the thinner (a female?) being 7 and the others 
9 or 92 inches in circumference, while that which Buffon described is 
only 5 inches. The rings are also more elevated, and reach nearer to 
the top than in Buffon’s figure. All the characters lead me to believe 
that the horns figured as those of the Koba by Buffon belong to Da- 
malis Pygarga. They afford very good venison. 
Colonel Hamilton Smith, in ‘ Griffith’s Animal Kingdom,’ de- 
scribed and figured the heads brought home by Messrs. Denham and 
Clapperton as 4. Senegalensis, but they are different from the one 
so called by Cuvier. Mr. Ogilby, in the ‘ Proceedings of the Zoolo- 
gical Society ’ (1826, 103), proposed to call these heads, 4. Corrigum. 
Under the name.of Antilope Koba, Schinz (Syn. Mam. ii. 407) 
combines the 4. defassa, Riippell, Damalis Senegalensis and Antilope 
adenota, H. Smith, the Koba of Buffon, and the Antilope Koba or 
Caama of Erxleben.
