528 AFRICAN GAME ANIMALS 



subfamily is distributed throughout all of Ethiopia and is 

 the most wide-spread group of antelopes in Africa. In past 

 geologic time duikers ranged as far as Algeria where they 

 are represented by two Pleistocene species. 



Key to the Genera 



Horns projecting straight back in line with or slightly below the 

 dorsal profile of the head, less than half the length 

 of the head, with broad base and triangular in 

 shape; hair unicolored without annulations 



Cephalophus 



Horns projecting backward and upward slightly above dorsal pro- 

 file of head, the length more than one-half the head, 

 base narrow, the horns long and cylindrical in shape; 

 hair annulated, the coat being vermiculated 



Sylvicapra 



Forest Duikers 



Cephalophus 



Cephalophus H. Smith, 1827, Griffith's Anim. Kingd., V, p. 344; t3^pe C. sylvi- 

 cultrix, the yellow-backed duiker. 



The forest duikers are characterized by their short, 

 broad horns, which project backward from the skull slightly 

 below the line of the dorsal profile of the head. The horns 

 are much shorter than the head and often so diminutive 

 as to be concealed by the long coronal tuft of hair. In 

 distinction to the bush duikers the coloration is uniform 

 or of solid colors, the hair not being annulated or vermic- 

 ulated. The forest duikers occur only in heavy forest 

 growth. Their centre of abundance is in the great Congo 

 forest in much of which they are the only representatives 

 of the Bovidcs. In distribution they are spread over all the 

 forested areas of Africa south of the Sahara Desert, with the 

 exception of Abyssinia.
