RUMINANTIA. 175 



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. Antilocapr/E of Ord. — ■Dicranoceros of Ham. 



Smith. 



Of all the forms of hollow horns tliis 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. pi. 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. — Tetracera, Leach. 



This subdivision, lately discovered in India, was not unknown to the 

 antients. ^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. chiearra, Hardw. ; Lin. Trans. XIV. pi. xv; and F. Cuv. 

 Mammif.-f- (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. J 



I. Tivo smooth horns. 



A.picta, and traxjo-camelus, Gm.; Buff. Supp. VI. pi. 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. pi. xvi ; Ysard in the Pyrenees. 

 (The Chamois). The only ruminating animal in the west of Europe 



* The A.palmata, Smith, lb. pi. iii, is only known to me hy its horns, which have 

 the antlers close to tbe base; perhaps they had been cut off. Some authors have 

 considered these antelopes also as the Mazcmes of Hernandez. 



f I should remark here, in relation to the obseiTations at page 523, Lin. Trans., 

 torn. 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 lum from supplying 

 what was deficient in his memoirs. 



X The y/. A-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.
