358 CLASS MAMMALIA. 



merely to make a distinction with the former, and because the 

 Caffies use this appellation for the present animal, and 

 Impoofo only for the other. The Dutch Colonists distinguish 

 the two, by adding- the word Bastard to the word Eland for 

 the Canna, which implies that they consider it a spurious 

 Elk, in the same manner as they distinguish two species of 

 Gnoo, by adding the same epithet of Bastard to one of 

 them. The Canna is not so large as the Impoof, more 

 slenderly made; the head is shorter, and the horns are de- 

 prived of the prominent spiral ridge, being only obtusely 

 angular in front, forming one spiral twist towards the 

 point; they are more parallel, very closely wrinkled, half- 

 way up, and bent back from their root beneath the line of 

 the face ; the point is turned forward, and their colour is 

 dirty horn. In one female specimen they measured twenty- 

 two inches, in a male seventeen inches ; these were more 

 robust, divergent, and somewhat undulating in their ascent, 

 and standing four inches asunder at base ; a circle of loose 

 soft hair of a darkish colour, feathers on the forehead, and 

 a narrow dark streak passes half way down the chaffron ; 

 the anterior canthus of the eyes is prolonged, and forms a 

 small lachrymary opening, beneath which there is a dark 

 angular spot, pointing towards the nose. The shoulder is not 

 much elevated, but the ridge of black hair is similar to that 

 of Oreas, excepting that it is not recurrent ; the dewlap is 

 small, furnished with long black hair ; the ears, not so long 

 as in the former, white on the inside and on the outside, to- 

 gether with the head, of a mixed tone of buff-gray and 

 brown ; the nose and space round the mouth, dark ; the rest 

 of the neck, body, &c, dark brown-gray ; a small space be- 

 tween the fore-legs white ; the tail entirely black does not 

 reach to the houghs, and the legs beneath the joints are 

 dark ; the hide is black. 



Occasional troops of this species are met on the same 

 grounds, with the Impoofo and Koodoo, but they never in-
