Mr. Gray observes, “‘ A fine pair has been at Knowsley some 
years. Thinking them new, I described them as A. annulipes. 
Mr. Ogilby has called it the Nagor, but it is scarcely the Nagor 
of Buffon. An adult male noticed by Mr. Ogilby as the Kod is 
now in the Museum of the Zoological Society; its horns, like 
the male at Knowsley, are much worn down. They whistle like a 
stag. 
Buffon (H. N. xii. 219. 267. t. 32. f. 1) figures a skull with 
horns, brought from Senegal by Adanson, under the name of 
Kob, which 1s also called the Petit Vache brune. Erxleben gave 
this figure the name of 4. Kod, and Pennant called it the Gam- 
bian Antelope, Syn.i. 39. The figures somewhat resemble the 
head of a half-grown male of this species, but the horns are ~ 
longer, and have more rings than the specimen in the British 
Museum; but I am inclined to agree with Mr. Ogilby in be- 
lieving that it was intended for this species. In the Jardin des 
Plantes they called the Sing-Sing the Kod of Senegal; this may 
be a mistake for the Koba. I may remark that the horns of the 
Koba in the same plate of Buffon are represented with more 
rings than are mentioned in the description.
