CHAPTER XVII 
DUIKERS AND SMALL ANTELOPES 
Duikers 
Subfamily Cephalophince 
The duikers form a very compact group of small and 
diminutive antelopes having short, straight horns project¬ 
ing backward in line with the dorsal profile of the head. 
The horns are quite straight and never exceed the head in 
length. A character peculiar to the duikers, and one by 
which they may always be recognized, is the linear arrange¬ 
ment of the anteorbital pores which form a long line on the 
sides of the snout in front of the eye. The duikers in gen¬ 
eral build are quite compact, with rather short legs and 
neck, low withers, and well-developed hind quarters. The 
hoofs are normal in shape, but the false hoofs show con¬ 
siderable specific variation in size. The tail is short but 
not rudimentary and is either well haired throughout or 
tufted. The female has four mammae. The skull has a 
large anteorbital fossa, quite equalling the orbit in size. 
The snout is of medium length with very broad triangular 
nasal bones expanding laterally and roofing over the ante¬ 
orbital fossa. Two generic groups are included, the typical 
or forest duikers and the bush or plains duikers, the latter 
being a recent offshoot which have forsaken the forest for 
a life in open bush country on the edge of plains. The
