THE MADOQUA, 
The Madoqua, Ajitilope Saltiana, if we except the Pigmy Antilope, is probably the smallest 
of homed quadrupeds, it being two feet long and fourteen inches high. Its color is similar to 
that of our common gray squirrel. It lives in pairs in the mountainous districts of Abyssinia. 
The natives of the country object to eating its flesh, from a superstitious belief that it frequents 
the society of monkeys and baboons. 
The FouR-TUFTED Antilope, Antilope quadriscopa, is found in Senegal. 
The Impoon, Duyker-Boc, or Diving-Buck, is of a yellowish-brown color, and grayish in win- 
ter. It gets its name from its habit of plunging under the bushes in its passage through the 
woods, instead of leaping over them like the generality of other antilopes. It is a common ani- 
mal in Caffraria and in all parts of the Cape Colony. It is found alone or in pairs, makes its way 
readily among the thickets and low bushes, and when pursued will from time to time stand np 
on its hind-legs to look round it, then dive under the branches to reappear again at some die- 
tance. 
This species is most probably the animal of which the female was long since imperfectly de- 
scribed by Grimm, and which has been admitted into systematic catalogues under the name of 
Antiloj^e Orhnmia. The A. Platous of Colonel Smith likewise appears to be identical with, or 
at most a casual variety of the Duyker-Boc, the characters upon which the separation is made 
being by no means constant, and some of them even of doubtful authenticity. The Gapra syl- 
vestris — Capra Africana of Grimm — is probably of this species. 
The Black-faced Philatomba, Antilo2oe Camplellice, differs from the Duyker by being much 
darker and more distinctly grizzled or dotted, and the under side being much whiter. It is pos- 
sible that it is only a variety of that species. 
Burchell's Bush-Boc, Antilope Burchellii, is easily known from the two former by its darker 
color, and by the under sides and inside of the legs being nearly of the same color as the back, 
and not white. It inhabits the districts more or less covered with underwood in Caffirland, and 
the country north of the Orange River. When interrupted or pursued by dogs, it springs with 
considerable activity over such bushes as may stand in its course, and endeavors to plunge into 
the closest bushes for concealment. 
The Abyssinian Bush-Goat, Antiloioe Madoqua, is of a yellowish-brown color, slightly punc- 
tulated with black. It inhabits Abyssinia, and is the Madoqua of Bruce. 
The Red-crowned Bush-Buck, Sylvicapra coronata, is a species found in "Western Africa, 
and is very distinct from the last, its color being lighter, and the fur less rigid and close-pressed. 
The White-backed Bush-Buck, or Bush-Goat, or Bush-Antilope, Antilope sylvicultrix, is. 
about five feet in length from the muzzle to the root of the tail, three feet high at the shoulder, 
and three feet two inches at the croup. Its proportions are heavy and ungainly, and bear a con- 
siderable resemblance to those of the Hog-Deer of India. It inhabits the west coast of Africa, 
about Sierra Leone and the sources of the Pongas and Quia rivers. It frequents the thickets and 
underwood of the upland plains and moderate mountain declivities, keeping close to the cover
