272 CLASS MAMMALIA. 



three quarters long ; the ears broad and oval ; the eyes 

 without lachrymary sinus, and probably without a pouch 

 below ; the hair on the head is very fine, short, and close, 

 of a pale buff colour ; but the dimensions of the legs, as 

 given by M. de Blainville (for they no longer exist), 

 make it doubtful whether they belonged to the same animal : 

 they have very long pointed hoofs. It is known by the 

 name of Madoka, in its native regions. 



The Tragelaphine Group. 



We preserve this group, with one exception, such as it 

 was originally instituted by M. de Blainville. The species 

 are few, uniting considerable elegance of form, with singu- 

 larly-opposed colours ; but their horns depart considerably 

 from the true Antilopine type, having ridges, which give 

 them an angular and compressed character, in some slightly 

 twisted, spiral, or lyrated. They have a small muzzle, no 

 suborbital opening, and the females, provided with four 

 mammas, are destitute of horns ? This group resides chiefly 

 in the deepest glens of woody mountains, living in solitude 

 or in pairs, feeding in the night, and springing with great 

 elasticity ; they are timid and vigilant, and seem not to 

 extend beyond Nigritia, and South Africa. 



The Boschbock. (A. Sylvatica.) The Boschbock is one 

 of those animals which unite elegance and vigour with a 

 singular distribution of lively colours. The fine specimen 

 in Mr. Burchell's collection, measured about five feet three 

 inches in length, two feet seven inches and a quarter at the 

 shoulder, and two feet nine inches at the croup ; but there 

 are specimens of larger dimensions. The head is seven inches, 

 and the horns ten inches in length ; the ears and tail each 

 six inches ; the horns are marked with an obsolete ridge in 

 front, and another very distinct in the rear ; they are placed 

 high on the head, parallel with the face, and in their ascent 

 are both spiral and lyrate, black, closely annulated, even
