ing Africa, of which many fine examples will be found in 
the Antelope House, there is an extensive series of small 
species. Indeed, the richness of Africa in antelopes, great 
and small, is almost beyond belief. The species of Asia and 
Europe are so few, and so inconspicuous, that they seem like 
so many stray wanderers from the Dark Continent. The 
fertile, grassy plains of the great Central African plateau 
have cradled scores of species, some of which have wandered 
into the deserts, the forests and the fluviatile swamps, and 
there made their permanent homes. 
The Black-Buck, or Sasin Antelope, (Antilope cervicapra), 
of the central plains of Hindustan, is one of the handsomest 
of the smaller antelopes. The horns of the male are long, 
strongly ringed, twisted spirally, and rise from the head in 
the shape of a V, sometimes to a length of 28 inches. At 
first the young males are fawn-colored, like the females, but 
as they grow older they steadily grow darker, until finally 
the whole upper body and lower neck are suffused with a 
rich, brown-black color. On the plains between the rivers 
Ganges and Jumna, herds of Black-Buck live in densely pop- 
ulated agricultural regions, and one of the greatest difficul- 
ties attendant upon its pursuit lies in shooting an animal 
without also shooting the native. 
The Reedbuck, (Cervicapra arundinum), of South Africa, 
below Angola and Mozambique, is closely related to the 
larger and much more showy waterbucks, but is distin- 
guished from them by the pronounced forward curve of its 
horns. In the western districts of Cape Colony, the number 
alive, in 1905, was estimated at 350 individuals. 
The Common Duiker Antelope, (Cephalophus grimmi), or 
for that matter, any species of Duiker—may be regarded 
as the representative of a large group of very small African 
antelopes, of wide distribution. There are about twenty 
species in all, and the great majority of them are very 
modestly colored, in coats of oue or two colors only. The 
prevailing tints are grayish brown and tawny red. The 
horns of the various species of Duikers are all very much 
alike. With but one or two exceptions, their horns are 
straight spikes from 3 to 5 inches in length. In shoulder 
height the Duikers vary from 14 to 30 inches, but the major- 
ity are between 17 and 22 inches. Only three or four species 
are strikingly colored. 
The Four-Horned Antelope, (Tetraceros quadricornis) is 
a small creature which looks like a duiker, but is very far
