252 CLASS MAMMALIA. 



distinct colour of their fur, easily escape the eyes of sports- 

 men : they seem to be confined to the eastern side of South 

 Africa, and are nowhere numerous. 



The Raphicerine Group. 



This group might be united with the former, if the cha- 

 racters of the horns were alone to be considered, for they 

 are destitute of every vestige of wrinkles or striae, perfectly 

 round, smooth, and very sharp, but not parallel. Their posi- 

 tion on the frontals is sub vertical, the forehead is very nar- 

 row, indicating animals of a diminutive size, whose resi- 

 dence, besides, being confined to the East Indies or the 

 islands of the Indian Archipelago, makes it probable that 

 when we shall be acquainted with the whole of their cha- 

 racters, distinctions will be observed which will confirm 

 their separation. At present the horns attached to a part of 

 the frontals is all that is known of them ; but these tend to 

 shew that Mr. Johnson alludes to them under the name of 

 Small Deer in his Sketches of Field Sports, &c. ; assigning 

 them a residence in the Rhamghur district, " Where the 

 Deer with four horns, or Chickara, are likewise found," and 

 describing them as not larger than an English hare, with 

 long ears, exceedingly active, and delicately formed. 



The Sharp-horned Antelope. (A. Acuticornis.) M. de 

 Blainville first described the horns of this species from the 

 fragment of a skull in the Royal College of Surgeons of 

 London ; they are only three inches long, perfectly round, 

 smooth, black, and pointed, about three-eighths of an inch 

 in diameter at base, slightly bent outwards, and diverging ; 

 the frontal crest, passing behind them, unites with a broad 

 parietal bone, with the sinciput much elevated, narrow, and 

 somewhat square ; on the parietal are many rugosities, 

 perhaps from disease. The fragment belonged to a young 

 animal, and was brought from India ; and upon comparison 

 with the Chickara of the next group, we have some doubt
