horns of that species ; but tliey are rather longer, and have more rings. Pennant (Syn. Mam, 38) has 
given the name of Senegal Antelope to Buffon's short account and figure, but has added to it the descrip- 
tion and the figure of the head of a skin which came from Amsterdam, and appears to be A. Caama 
of South Africa. Cuvier (Diet. Sci. Nat. ii. 235) has translated Pennant's name to A. Senegalensis. 
Erxleben (Syn. 293) and Zimmerman (Zool. 345) have translated Pennant's description of his skin of 
A. Caama, and called it A. Koba, referring to Buffon's description and Daubenton's figure. Fischer, 
Hamilton Smith and M. Sundevall regard the Koba of Buffon the same as the Korrigum of Denham and 
Clapperton, but the horns of that species are considerably longer and much thicker at the base than those 
described by Daubenton, and the aiinulations of the horns are higher and more regular: but it maybe 
remarked that Buffon describes his horns as having eleven or twelve rings, but figures them as having 
seventeen or eighteen. Mr. Ogilby (Penny Cyclopaedia and the Proceedings of the Zoological Society) con- 
siders Buflfon's Koba to be the Sing-Sing ; and in the length of the horns, and in the number, disposition 
and form of the rings it more nearly agrees with the horns of that species than of that of the A. Pygarga, 
to Avhich Pallas first referred it ; but it is much more lyrated than any horns of the Sing-Sing I have seen ; 
indeed, not one of the specimens which have come under my observation have had any inclination to assume 
that form : but as this is the only Western-African species which in any way agrees with Buffon'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. Schinz erroneously considers Damalis Senegalensis, Antilope adenota and A.forfeoc (H. Smith) 
as synonyms of this species.

Tlie head of the female covered with the skin from Macarthy's Island, on the coast of Gambia, which 
Mr. Whitfield brought home, did not appear to differ from the specimen from the Cape which we have 
in the Museum. The species does not appear to be uncommon in the locality, for Mr. Whitfield brought 
over several other pairs of horns. He informs me the flesh is very good venison.' "It is called Docoi 
or White Mouth by the Mandingoes, Kob and Koba by the JoliflTs, and Vache hrune by the French at 
Senegal." This is certainly 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. harbata (Daniels) appears to be only a bad drawing of this species.

The size of the Common Stag, Cerms Elaphus. M. Sundevall observes that it is as different from 
A. Equina, as the species of Eleotragi and Tragelaphi are from one another ; and he observes, in a letter I 
have just received, " I must tell you, that after the inspection of a whole series of A. Equina, which Wahl- 
berg brought home, I am convinced that the A. leucoplicea of Pallas is a very distinct race. Our stuffed 
specimen, that must have been adult, has much smaller hoofs than the very young A. Equina, male as well 
as female, amongst Wahlberg's, and in the tuft over the lachrymal sinus, as I have shortly expressed in the 
printed survey." 
When I examined the specimen at Paris I regarded it as a young or rather dwarf specimen of^. Equina, 
and the absence of the nuchal crest led to this behef; and I am not satisfied that the number of rings on 
the horns are a sufficient proof of its being adult.
