Colonel Hamilton Smith formed a genus for two pairs of horns on part of the frontal bones in the 
College of Surgeons belonging to this group of Antelopes, which he called Raphkerus acuticornis and R. 
suhulata (Griffith, A. K. t. 181. f. 2, 1). The figures are not sufficient to identify the species, and we now 
know that the horns of the same species differ greatly in individuals of the same species, and during the 
growth of the same specimen. R. acuticornis may be the horns of the Duyker Boc, CepJi. Grimmia ? 
The Cervine Antelopes have an elongated tail, cylindrical at the base, and with long hair at the end, 
often forming a compressed ridge ; the body heavy and the limbs strong. They are of a large size. 
* Neck not maned. 
15. ADENOTA, 
with cordate, moderate, cervine muffle; nose hairy between the back of the nostrils; horns sublyrate, 
ringed, when young rather recurved ; place of tear-bag covered with a tuft of hair ; hair of the back 
whorled, of dorsal line and back of head reversed ; tail elongate, hairy. 
This genus is very like Eleotragus, but has a smaller, more cervine muzzle and lyrated horns ; it differs 
from Cohus in the form of the tail, and wanting the mane, and from both in having a tuft of hair in the 
front of the orbit. 
The tEquitoon. Adenota Kob. Tab. XIV. and XV. 
Pale brown ; end of nose, inside of ears, chest, belly, inside of legs and thighs, tip of tail, and band 
above hoofs white ; front of fore and hind legs, and end of ears and tail black ; hair of the dorsal 
line reversed, with a whorl on the shoulders and loins.

Inhabits W. Africa ; Gambia. Called ^quitoon by the Joliffs, and Koh by the Mandingoes. 
A fine pair has been at Knowsley some years. Thinking them new, I described them as A. anmlipes. 
Mr. Ogilby has called it the Nagor, but it is scarcely the Nagor of BufFon. An adult male noticed by 
Mr. Ogilby as the Koh 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 Adan- 
son, under the name of Kob, which is also called the Petit mche brune. Erxleben gave this figure the 
name of A. kob, and Pennant called it the Gambian 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 our 
specimen in the British Museum ; but 1 am inclined to agree with Mr. Ogilby in believing that it was 
intended for this species. In the Jardin des Plantes they called the Sing-Sing the Kob 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. 
Colonel Hamilton Smith describes and figures a male and female specimen which were alive in Exeter 
Change, and figures the male and its skull and horns under the name of A. adenota, which well agrees with 
this species, and has the peculiar distribution of its hair; hence its name: but he says, it has "a long open 
suborbital slit, and small black brushes on the knees;" but I suspect that must be a mistake, as he him- 
self observes no lachrymal cavity was found in the skull. He might have mistaken the tuft of hair for the 
gland at the distance at which he saw the specimens. He also (G. A. K. iv. 221) described a specimen 
which was in Exeter Change, which he regarded as the Gambian Antelope of Pennant, and calls A.forfex. 
His characters agree in most particulars with this species, but he says it had " a long lachrymal sinus, 
and had small brushes on the knees." If there was not some mistake in transcribing these descriptions, 
both these animals should be Gazellas, but I have never seen any which agreed with them. 
The young male in the British Museum shows the development of the horns of these animals. The 
upper rings of the growing horn fall off in large thick flakes as the horn increases in size beneath : this 
explains how the extent of the smooth tapering part of the horns increases in length as the horn grows, 
and how the number of rings are found to be nearly the same in the various ages, and different individuals 
of the various species. Mr. Whitfield also informs me that the scrotum is rarely developed or dependent 
externally in different kinds of Antelopes before they have completed their first year.
