bush country or the southern edge of the sand desert of 
the Sahara in the White Nile region. 
The type of the Nile bush duiker was shot by Colonel 
Roosevelt near Rhino Camp, Lado Enclave, during his 
quest for the white rhinoceros in that district, and was 
described in 1912 by Heller. The earliest mention of 
the occurrence of the bush duiker in the Nile Valley is 
apparently Heuglin’s reference, in 1869, in his account of 
his explorations on the White Nile, to some skins offered 
him by the natives at Meshra-er-Rek in the Bahr-el- 
Ghazal district. Schweinfurth included it in his list of 
Nile mammals published in 1873, and gives the native 
names by which it is known in the districts through which 
he travelled. 
The Nile bush duiker may be known by its small size 
from any other race. Its distinctive color characters are 
the more grayish tone of the dorsal parts, the absence or 
faintness of the dark stripes on the legs below the knees, 
and the lighter brownish-drab color of the dark bands above 
the hoofs. Other characters are its short ears and the 
small size of the skull, which is less than six inches in length. 
The dorsal body coloration is wood-brown vermiculated 
with blackish and darkest on the median line. Basally the 
hair is ecru-drab. The sides of the body are lighter, be¬ 
coming pure fawn where they meet the white of the under¬ 
parts. The neck shows very little black vermiculation, 
being almost wholly cinnamon-brown, this color extending 
onto the head, where it deepens to russet on the crown and 
borders the black median stripe which extends from the rhi- 
narium to the base of the horns. The cheeks and sides of 
the face are lighter, being fawn color. The rump is more 
grayish than the back, the drab-gray predominating. The 
tail is marked by a heavy black dorsal stripe, the sides and 
lower surfaces are white, and the tip is chiefly white. The 
belly and the inside of the legs are white, and the hair at 
the extreme base is drab. The chest is mixed white and 
fawn with the drab of the basal part showing through. The 
lower throat is fawn, like the sides. The chin, upper lips, 
and throat are white. The tip of the chin is marked by 
dark-brown spot on each side separated by the white of the 
throat. The limbs are grayish-fawn, like the back, with a
