The Wart-Hogs. 
Genus Phcicochcerus. 
As Africa possesses in the red bush-pig the handsomest representative of the 
Swine family, so in the wart-hogs it presents us with the most hideous members, 
not only of that group, but of the whole Ungulate order. 
The wart-hogs, of which there are two nearly allied species, are characterised 
by the enormous size of their heads, in which the lower part of the face is 
extremely flat and broad, while below each eye is a huge warty protuberance 
^lian’s wart-hog ( t \; nat. size). 
between which and the tusk there are two other of smaller size. The head is likewise 
distinguished by the great length of the muzzle, and the consequent backward 
position of the eyes; the hideous physiognomy being completed by the huge tusks 
with which the jaws of both sexes are armed, those of the upper jaw being 
considerably longer than those of the lower, or just the reverse of what occurs in 
the true pigs. This difference in the proportionate length of the upper and lower 
tusks in the two groups is due to the circumstance that in the wart-hogs the lower 
pair only bite against the inferior surface of the upper ones, instead of abrading 
their whole summits. The upper tusks are devoid of enamel except at their tips,
