ORDER RUMINANTIA. 249 



Colony of the Cape of Good Hope, but is very rare, residing 

 entirely among the rocky cliffs of the eastern districts, and 

 evincing great vigilance and activity. The specimens we 

 have seen came from Algoa Bay. In the Dutch language 

 the name Steenbock properly signifies the Ibex, and can 

 have been bestowed upon the species only on account of a 

 similarity of manners between the two animals. 



The Vlackte Steenbock. (A. Rufescens.) We are in- 

 debted to Mr. Burchell for a knowledge of the male of this 

 species, which might be considered as the young of the for- 

 mer, but that its residence is on the plains, as the colonial 

 name Vlackte, plain or open country, implies ; and that the 

 brilliant colouring of the fur is not a sign of nonage. 

 The horns are sub vertical, reclining a little at base, with 

 the tips slightly bent, so as to point upwards ; they are 

 round, black, parallel, sharp, perfectly smooth, or without 

 any wrinkles or striae, three inches and a half long, one 

 inch and a half asunder at base, two inches at the tips : the 

 ears are longer than in the preceding, measuring four 

 inches and a half, and reaching beyond the points of the 

 horns, rather rounded at the tips, lined on the edges and 

 inside with white hair, streaked with dark lines inside, and 

 gray outside ; the head is somewhat squarer, tapering gra- 

 dually to the nose, and not as in the former contracting 

 suddenly before the orbits : between the nostrils there is a 

 small black muzzle ; the head, neck, back, flanks, upper 

 arms, and thighs, are bright fulvous-red, with something of 

 a cast of crimson ; a spot along the lower eyelids, and pass- 

 ing beneath the lachrymary sinus, is white, as is also the 

 under jaw, throat, breast, internal face of the fore-legs, 

 belly, interior of the thighs to the edge of the buttocks, and 

 after part of the hind-legs and pasterns ; the rest of the 

 legs from the joint downwards are pale rufous: no tail is 

 visible beyond the hair of the buttocks. 



Of this species we saw the drawing of a female taken at
