ruminating order. It was, we believe, obtained in the in- 

 terior of the west side of Caffraria. 



The Duiker Bock. {A. Mergens.) There is a particular 

 distinguishing character about the horns of this species, 

 which separate it unequivocally from all other Antelopes. 

 It consists in a ridge more or less obsolete, rising on the 

 anterior surface, and passing through the four or five 

 annuli of the middle, but not through the closer wrinkles 

 at the base. The horns do not exceed four inches in length, 

 somewhat more distant at their root than in the preceding, 

 diverging slightly, bending outwards and more reclining 

 along the plane of the face, black, and obtusely pointed ; 

 the total length of the animal is from three feet two inches 

 to three feet six inches, and the height about twenty-one 

 inches at the shoulder, and twenty-three on the croup, or 

 something more ; the forehead is entirely covered with 

 long coarse hair, reaching above the base of the horns, of a 

 fulvous colour, which passes also over the back of the ears : 

 these are five inches long with three dark streaks on their 

 inner surface; the chaffron has the same black streak 

 down to the muzzle, and the legs similar dark markings, 

 and somewhat the same robust structure as the former, but 

 on the side of the nose a dark naked slit is very percept- 

 ible ; the fur is of a light brown colour, close and smooth, 

 and the throat, breast, belly, inside of the limbs, and under 

 part of the tail, are partially white. In the female the 

 white extends along the back of the legs, and the dark 

 colours on the front are wanting. Among the different 

 specimens examined, the fulvous hair of the forehead was 

 sometimes tarnished, and the annuli of the horns scarce 

 perceptible, but the basal wrinkles and the anterior ridge 

 always prominent. The frontal ornament is then often in 

 the shape of a single tuft placed between the ears, espe- 

 cially in the females, and the whitish parts ashy. These 

 may be signs of youth, for in an old male the colour of the
