part of the cheeks, the lips and beneath the chin are of the same 

 colour, but the whole throat or under surface of the neck is pale 

 reddish brown, like the back and sides. The tail is covered above 

 with short reddish hair like that of the body, but it is perfectly naked 

 beneath, and in form and length resembles the tail of some species 

 of Deer (Cervus). The nose is hairy like that of a Goat; the animal 

 is furnished with lachrymal sinuses of considerable size, opening by 

 very obvious apertures of a circular form ; it has inguinal pores and 

 two teats, as in the common Antelope (A. Cervicapra); large sj^urious 

 hoofs, and no appearance of scopts or knee-brushes either on the 

 anterior or posterior extremities. These characters will not permit 

 it to be associated with any known group of Ruminants. That it is 

 not merely a Deer which has cast its horns, is proved by the absence 

 of the pedestals which support these organs in the solid-horned Ru- 

 minants, as well as by the hairy lips, two teats and inguinal pores ; 

 neither can it be a Sheep or a Goaf, as is evinced by the lachrymal 

 sinuses, inguinal pores, and the length and form of the tail, which, 

 in the wild species of these genera, is nearly tuberculous. The sup- 

 position of its being the female of A. Furcifer is disproved by the sex 

 of the specimen ; in other respects, the existence of large spurious 

 hoofs shows plainly enough that it has no affinity to that animal. 

 There is but one other supposition: may it not be a species of An- 

 telope allied to the typical group of that genus? and may not the 

 abortive horns of the present specimen be the result of some acci- 

 dent? This may certainly be the case ; the other characters of the 

 specimen agree with those of the common Indian Antelope, and if the 

 animal should eventually j^rove to belong to that genus, it may bear 

 the specific name of A. Ixalus, which the classical scholar will re- 

 cognise as the name of an undetermined species of Ruminant men- 

 tioned in the Iliad. 



" 2. AntUope Eurycerus. Of this magnificent and hitherto unde- 

 scribed species, two pairs of horns, one attached to the skuU, the 

 other to the integuments of the head, have long existed in the So- 

 ciety's collection. Their origin is unknown, but I have reason to 

 believe that they come from Western Africa. Tlieir length in a 

 straight line is 2 feet 1^ inch ; on the curve, 2 feet 7o inches ; 

 their circumference at the base is 10 inches ; their distance at base 

 1 inch, and at the points 11 inches. In form they bear some re- 

 semblance to those of A. Sfrepsiceros, being wrinkled as in that spe- 

 cies, and havmg a prominent ridge on their posterior face ; but they 

 form onlj- one spiral twist instead of two, and their direction through- 

 out lies in the plane of the forehead, whilst in the Koodoo these two 

 planes form an angle of about 100°. The characters of the skull are 

 likewise similar to those of the Koodoo, but it is broader and larger 

 than in that animal. The points of the horns are of an ivory colour. 

 The animal has a large muzzle, but is without lachrymal sinuses ; it 

 has a white band across the face, immediately under the eyes, and two 

 white spots on each cheek. All these characters are distinctive of 

 the natural group which includes the Koodoo, the present sjiecies, 

 the Boshbok, the Guib, and the beautiful species mentioned by Mr.
