cous color, with the outer sides of the limbs dark. It inhabits the south of Africa, between Lati- 
koo and the tropic of Capricorn. It lives in herds of six or ten, in the flat or wooded districts. 
The flesh is esteemed. When not disturbed it is confiding and curious, but when hunted it be- 
comes shy. 
The KoRRiGUM, A. Senegalensis, is of a reddish-gray color ; the front of the face, from nose to 
occiput, a small spot behind the eyes, a small streak above the angle of the mouth, streak on out- 
side of limbs above the knees, and tuft of the tail, black. This animal is a native of West Africa, 
on the Gambia Eiver and Macarthy's Island. It is called Yonga or Yongah by the Joliffs, and 
Tan-Rong by the Mandingoes. 
The NuNNi or Bonte-Boc, A. pygarga, is of a simple red color; the outer side of the limbs 
darker ; the streak between the horns, face, and rump above the tail, white ; the temple and up- 
per part of throat whitish; the legs whitish; upper and lower part brown, varied. The female 
has the throat and under part of the body white. The terms Kob and Koha are applied to vari- 
ous kinds of antilopes by the negroes, and probably also to this species. 
The Blbss-Boc, A. albifrons^ described by Burchell, is of an exceedingly slender form, and is 
found in South Africa. 
THE ADDAX. 
The Adax, a. Addax, is mentioned by Pliny under the name of Strepsiceros, which, he says, 
the x4_fricans call Addax. From the time of Pliny to a recent date this animal was not discov- 
ered ; but it is now ascertained to exist in Central Africa, where it lives in pairs on the sandy 
deserts. The body is five feet long, the height three feet. The general color is grayish-white, 
though the head and neck are of a reddish-brown. 
Genus CAPRICORNIS : Caprico7-7iis. — This comprises the Cambing Outan, C. Sumatrensis, 
the Antilojoe Sumatrensis of Shaw, found in Sumatra; the Thar, Serow, or Imo, C. Thar or Bu- 
halina^iowxid in ISTepaul; the Japanese Goat-Antilope, C. crispa of Temminck, found in Japan; 
and the Goral or Nepaul Bouquetin, a large kind, found in herds in the elevated plains of 
Nepaul. This last forms the genus Kemas of Ogilby and Nemorliedus of Gray. 
Genus ANTILOCAPRA : Antilocapra.. — Of this there is a single species, the Cabrit or Prong- 
horned Antilope of North America, A. furdfer^ the only kind of antilope found on this conti- 
nent. It differs from all the other members of the tribe in several respects, and especially in 
having a prong or branch to the horns. It is about four feet long and three feet high; the horns 
rise perpendicularly from the skull till within two or three inches of the points, where they curve 
suddenly backward and inward, forming a small hook like those of the chamois. The prong is 
situated upon their anterior face, and in adult animals about half-way up from the root ; below it
