are little known, partly owing to their being too small to afford any sport and 
with but poor horns for trophies, but mainly owing to their inhabiting thick 
bush, so that they are hardly ever seen. One species, however, the common 
S. African Duiker, the popular name of which we have extended to all the 
members of the genus, is well known to every sportsman who has visited that 
country, both on account of its extreme abundance in most localities, and of 
its inhabiting more open districts than its congeners, the Bush-Duikers. It has 
allies in Abyssinia and Senegal, and the three have together been separated 
by some authors as a distinct genus, but this separation we are not at present 
prepared to endorse. 
Considering, then, all the Duikers as forming but one genus, we may 
distinguish them according to the following synopsis, although, as three or 
four of the species are known from very insufficient materials, we may expect 
that the characters will require some modification hereafter. 
From the localities appended it will be seen that the large majority of the 
species are West African in habitat, the great tropical forest which covers so 
much of that part of Africa being apparently especially suited to their bush- 
loving habits. 
A. Horns, when present, pointed directly backwards, in a line with, or below 
the line of, the nasal profile; generally present in the female. Ears 
moderate or short, rounded, their length much less than the distance 
from the eye to the nose. General colour fulvous, red, grey, or black, 
generally marked or striped. (BusH-DUIKERs.) 
a. Size large: hind foot (without hoof) more than 11 in.; basal length of 
skull more than 9°5. 
a’. General colour blackish, with a yellowish lumbar stripe.-—W. Africa. 
19. C. sylvicultria. 
b'. General colour of body grey, of head and neck black.—W. Africa. 
20. C. gentinkt. 
b. Size medium or small: hind foot less than 10 in.; basal length of 
skull less than 8:5. 
a’. General ground-colour fulvous, rufous, or chestnut. 
a2. Back not transversely striped. No heel-tufts. 
a. Colour quite uniform, no mesial dark markings on the face or
