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 cervicapm); 

 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 one 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 winch looks like a duiker, but is very far
