ORDER RUMINANTIA. 275 



to the flank, and the other towards the groin, both are in- 

 tersected at right angles by two or three similar narrow 

 lines across the centre of the back, followed by four or five 

 others, but shorter across the croup ; on the thigh are nine 

 or ten small white spots ; two others are near the cubitus of 

 the fore-legs, and one or two on the cheek beneath the eyes^ 

 and the extreme edge of the buttocks, is white; on the belly 

 the rufous is duller, and in the female that part, the throat 

 and breast are wholly white. This sex also wants the darker 

 tone on the middle of the forehead, on the posterior pasterns, 

 and the streak more or less extended on the shanks of the 

 fore-legs, as usually seen in the males. 



Of this species we have compared a male and a female. 

 It is found in the woods and plains of the country of the 

 Jalofs, and on the Senegal. Professor Lichtenstein, and 

 others, consider it as sometimes found in Caffraria^ but 

 Mr. Burchell, during his four years' residence in the in- 

 terior, did not observe it, nor is the assertion of the colonists 

 to be relied on, as their Bontebock is commonly applied to 

 A. Euchore, and even to Pygargus. 



The Ribbed Antelope. (A. Phalerata.) We separate 

 from the Guib the present species, which M. Desmarets 

 considered to differ only on account of nonage ; but the 

 constant recurrence of the same marks of difference in the 

 specimens we have examined, warrant the opinion of a dif- 

 ference of species. The horns are small, three or four inches 

 long, reclining, conical, not compressed, without ridges or 

 transverse protuberance in front. Although the animal is 

 altogether smaller, the forehead is comparatively broader, 

 the nose shorter, and terminated by a small black muzzle : 

 the fur is less vivid in colour. A black line of hair passes 

 along the spine, edged on each side with white, commenc- 

 ing on the withers, and terminating at the root of the tail ; 

 from each of the white lines nine others descend perpendi- 

 cularly in the form of narrow ribs, without, however, unit-
