size and darkest coloration in the Cape region. The sexes 
are alike in coloration, but the female exceeds the male 
somewhat in body size. The young differ only from the 
adults in tone of coloration, being darker and uniformly 
vermiculated with blackish. The under-parts are drab 
rather than white, and the head lacks any indication of 
the bright tawny coloration of the adult, although the 
black median stripe is well marked on the snout and 
forehead. 
The duiker is widely distributed not only laterally but 
vertically. We found it feeding at night on the Aberdare 
Mountains when the temperature was below freezing, and 
we found it feeding at noon on the hot, dry plains of the 
Lado, where the leaves of the acacias were shrivelled and 
the thermometer stood high up in the nineties. It is a 
solitary little animal, even two being rarely found together. 
It is never found far away from thick cover, and when 
alarmed bolts into it without turning to look back. It runs 
with head extended, occasionally bounding high into the 
air, and in the bush it runs at full speed in zigzags through 
places which a hunter can hardly traverse at all. All these 
bush antelope—bongo, bushbuck, duiker—go at speed, nose 
straight out, through and under a tangle of branches which it 
seems literally incredible that they can penetrate. Duikers 
are browsers; they feed on twigs, leaves, bean pods, and 
fruits. We found them eating wild olives and also the 
berries of a plant that looked like nightshade; and in the 
Lado they ate grass tips and the stems and leaves of a low- 
growing bush plant. 
The commonest food of the bush duiker is the foliage 
and yellow berries of the nightshade, Solarium campylacan- 
thum . On the summit of the Aberdare Range we found the
