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 have been able to examine with BufFon's figure and descrip- 

 tions, I find them all longer and much thicker at the base than Buf- 

 fon describes them ; the thinner (a female ?) being 7 and the others 

 9 or 9^ 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 beheve 

 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 A. 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, A. Corrigum.
