RUMINANTIA., I75 
ish-grey stripes crossed with white ones; large horns, which are pe- 
culiar to the male; they are smooth, with a triple flexure, with a 
single longitudinal ridge slightly spiral; a small beard beneath the 
chin; a mane along the spine: it lives isolated to the north of the 
Cape. 
i. Horns bifurcated. Anvitocapra of Ord.—Dicranoceros of Ham. 
Smith. 
Of all the forms of hollow horns this is the most singular; a compres- 
sed fork is given off from their base or trunk, almost like the tine or ant- 
ler of a deer; the pointed tips curve backwards. The most known spe- 
cies is, 
A. furcifera, Ham. Smith, Lin. Trans. XIII. pl. ii; the Cabril 
of the Canadians. It inhabits the vast prairies of the middle and 
western parts of North America, where it roams in large herds. Its 
size is about that of the roebuck; hair thick, undulated, and reddish; 
the tine of the horns is about the middle of the height.* 
k. Four horns.—Terracera, Leach. 
This subdivision, lately discovered in India, was not unknown to the 
antients. A¥lian speaks of it, 1. XV. c. xiv, by the name of the Four- 
horned Oryx; the anterior pair are before the eyes, the posterior com- 
pletely behind the frontal. 
A. chicarra, Hardw.; Lin. Trans. XIV. pl. xv; and F. Cuv. 
Mammif.+ (The Tchicarra). About the size of a roebuck, and of 
an almost uniform fawn colour. The female has no horns. Found 
in the forests of Hindostan. 
l. Two smooth horns. 
A. picta, and trago-camelus, Gm.; Buff. Supp. VI. pl. x and xi. 
(The Nylgau). As large as a stag, or larger; the horns short and 
bent forwards; a beard under the middle of the neck; hair greyish; 
double, black and white, strongly marked rings on all the feet just 
above the hoof. The female have no horns. This species is from 
India. 
A. rupicapra, L.; Buff. XII. pl. xvi; Ysard in the Pyrenees. 
(The Chamois). The only ruminating animal in the west of Europe 
* The 4. palmata, Smith, Ib. pl. iii, is only known to me by its horns, which have 
the antlers close to the base; perhaps they had been cut off. Some authors have 
considered these antelopes also as the Mazames of Hernandez. 
¢ I should remark here, in relation to the observations at page 523, Lin. Trans., 
tom. XIV, that it was not the fault of the late M.du Vaucel, that the figure and de- 
scription of the Tchicarra were attributed to him in the Hist.des Mammif. His 
consignments were not always complete; a drawing frequently arrived without any 
description or explanation, and his premature death prevented him from supplying 
what was deficient in his memoirs. 
t The 4. 4-cornis, Blainv., is only known to me by a cranium, the anterior horns 
of which are proportionally larger, Jour.de Phys. Aout 1815. Perhaps it is merely 
a difference arising from age.
