CHAPTER XIX 
THE DIKDIKS 
Subfamily Rhynchotragince 
The dikdiks are antelopes of very small size, having the 
snout produced into a short proboscis and the anteorbital 
gland of large size and opening by a circular orifice on the 
face. The tail is rudimentary, and less than two inches 
long. The male alone is horned. The horns are short, 
ringed, and project backward in a line with the profile of 
the snout. The female has four mammae. The hoofs are 
slender and the false hoofs are minute. The coloration of 
the sexes is alike, but the tuft of long hair on the forehead 
is decidedly coarser and denser in the male. The color pat¬ 
tern of the young at birth is identical to that of the adults. 
The female is distinctly larger than the male. The skull 
has the anterior narial opening greatly enlarged to accom¬ 
modate the proboscis, which is brought about partially by 
the nasal bones being much reduced, their length being not 
greater than their width. The premaxillae are very slender 
in the typical genus, and reduced so that they do not extend 
more than half-way to the nasal bones. The anteorbital 
fossae are much enlarged to accommodate the large ante¬ 
orbital glands., Young skulls in which the first molars are 
just erupting show well-developed upper canine teeth, but 
these are absorbed again by the time the second molars are 
erupted. Similar canine teeth are found in Gazella at the
