262 CLASS MAMMALIA. 



the forehead was covered with longish hair of a mixed buff 

 and sepia-gray, darker down the nose ; the back of the 

 ears similarly coloured ; from their root, passing round the 

 eyes to the mouth, the colour was buff. A small lachrymary 

 opening appeared under the eye, and between that and the 

 nose a narrow dark streak, apparently not open but naked. 

 The cheeks, neck, back, flanks, and thighs, were of a similar 

 buff and sepia-gray, paler on the flank, and towards the 

 belly and buttock edged with an indistinct darker band ; 

 the lips, breast, belly, inside of the limbs, buttocks, and 

 houghs, were white ; the external and anterior face of the 

 arms and hind-legs dirty buff, marked above the knees with 

 four narrow and dark cross streaks, similar to those usually 

 seen on the legs of mules ; but the most remarkable cha- 

 racter was, that brushes or tufts of hair of a dark colour 

 marked each leg below the knees of the anterior, and on 

 the upper anterior face of the posterior ; the pasterns 

 were short, and the hoofs small, black, and pointed. The 

 individual was brought from Senegal. 



BurcheWs Antelope. {A. Burchellii.) In the Cephalo- 

 phine group, the Duiker or Dodging Antelope appears to 

 form not a species alone, but a small racemulus, being 

 surrounded by others so nearly allied, that they may be re- 

 garded as varieties, although we believe it most advisable 

 to describe them separately, leaving the question of iden- 

 tity to future investigation. At the head of these, appears 

 a specimen shot by Mr. Burchell's hunters, who, as we 

 were informed, considered it as new to them, nor did a 

 second come under his observation. The spoils of the animal 

 are now in the British Museum, and although the charac- 

 ters in general would refer them to a A. Mergens, yet when 

 compared with several specimens of that species, procured 

 by the same indefatigable naturalist, the differences are 

 sufficiently obvious. The total length, from the nose to the 

 rump, is three feet five inches ; from the nose to the horns
