longer and more abundant. The hair of the chin and neck is long 

 and rigid in all seasons, and even in the young animals. The tail of 

 the adult specimen is cylindrical and nearly bald, ending in a tuft of 

 black hair ; in the young specimens, especially in the winter fur, the 

 base of the tail is fringed with hair on each side. The male is much 

 brighter coloured, and the chest and belly are nearly black like the 

 legs. The hinder parts of the rump of the young animals are greyish 

 white ; in the older specimens it becomes pure white and broader in 

 extent. 



This animal is called Sing -Sing by all the negroes. They do not 

 think their flocks of cattle will be healthy or fruitful unless they have 

 one of the Sing-Sings accompanying them, as some persons think a 

 Goat necessary to be in a stable in England. The English on the 

 Gambia call it the Jackass Beer from its appearance, and it is called 

 Koba and Kassimause by the negroes at Macarthy's Island. Its flesh 

 is very strong, unpleasant, and scarcely palatable. 



As far as I could judge by my recollection and description, the 

 adult specimen at Knowsley, the young male and adult female in the 

 British Museum, the male and female at Frankfort, and the adult 

 male in the Paris menageries, are the same species. 



BufFon figured (Hist. Nat. 210, 267. xii. t. 32. f. 2) under the 

 name of Koba a pair of horns which were in the library of St. Victor 

 at Paris. He described them as larger and more curved above than 

 those of the Kob, eighteen inches long and five inches in circumfer- 

 ence at the base, and he refers them to an animal which Adanson 

 says is called Koba in Senegal, and the Great Brown Cow by the 

 French colonists. Pallas refers these horns to A. Pygargus, and the 

 figures and description agree in many particulars with the horns of 

 that species ; but they are rather longer, and have more rings. Pen- 

 nant (Syn. Mam. 38) has given the name of Senegal Antelope to 

 BufFon' s short account and figure, but has added to it the description 

 and the figure of the head of a skin which came from Amsterdam, 

 and appears to be A. Caama of South Africa. Cuvier (Diet. Sci. 

 Nat. ii. 235) has translated Pennant's name to A. Senegalensis. 

 Erxleben (Syn. 293) and Zimmerman (Zool. 345) have translated 

 Pennant's description of his skin of A. Caama, and called it A. Koba y 

 referring to BufFon' s description and Daubenton's figure. Fischer, 

 Hamilton Smith and M. Sundevall regard the Koba of BufFon the 

 same as the Korrigum of Denham and Clapperton, but the horns of 

 that species are considerably longer and much thicker at the base than 

 those described by Daubenton, and the annulations of the horns are 

 higher and more regular : it may however be remarked that BufFon 

 describes his horns as having eleven or twelve rings, but figures them 

 as having seventeen or eighteen. Mr. Ogilby (Penny Cyclopaedia 

 and the Proceedings of the Zoological Society) considers BufFon' s 

 Koba to be the Sing-Sing ; and in the length of the horns, and in the 

 number, disposition and form of the rings, his figure more nearly 

 agrees with the horns of that species than of that of the A. Pygarga, 

 to which Pallas first referred it ; but the horns are represented much 

 more ly rated than any horns of the Sing- Sing I have seen ; indeed,
