ORDER RUMINANTIA. 237 



form, beside a multiplicity of horns and skulls ; among the 

 horns there are sometimes specimens perfectly smooth, and 

 larger than those usually seen. Professor Lichtenstein, 

 and others, have suspected them to belong to an unknown 

 species ; they are joined together with opposite points, to 

 form a kind of cress worn in the girdle of some Mahomedan 

 sectaries, who profess not to bear arms. 



The Reduncine Group, 



The Antelopes of this group, distinguished principally by 

 horns more or less bending forward, begin to recede from 

 the elegance and fine proportions of the previous sections ; 

 they form a separate racemus, distinguished by the charac- 

 ter of the horns, which are placed behind the orbits, but 

 little reclined, mostly short, round, black, and annulated 

 halfway up, or less; their ears are long, open, oval, filled 

 on the inside with white hairs ; they have no externally 

 developed suborbitary sinus ; the nostrils are ovine, or in a 

 small muzzle ; the fur on the hides, which are white or 

 black, is larger, looser, undulating; the tails reach below 

 the buttocks, and are thickly set along the edges and tip with 

 long loose hair, but no tufts ; their limbs are strong and 

 lower in proportion than in true Antelopes, and their resi- 

 dence requires them to have more power in springing than 

 fleetness, for they prefer open rocky mountains, or the 

 cover of reeds and bushes along the banks, or the beds of 

 desiccated upland rivers. The females are without horns, 

 and provided with four mammae ; they are not gregarious, 

 but live in pairs, or small families of six or eight. The 

 Kemas of iElian would seem to refer to this group, or to 

 be, as we shall find again in the next, intermediate; but 

 that, and the chain to which we apply it, must ultimately 

 be decided when the Bootan species shall be better known. 



The Rietbock. (A. Eleotragus.) Mr. Allaman first de- 

 scribed this species from the notes and a skin forwarded to
