VERTEBRATA. 
face is partly black, and tlie tail is long, reaching below the knee. Specimens of this kind are in 
the menageries of London and Paris. The name Clioiropotamns having been applied to an extinct 
species, that of Potamochoerus has recently been given to this species by Gray. 
The Masked Boar, 8. larvatus of F. Cavier, S. Africanus of Schreber, has tusks like the com 
mon hog, bnt on each side of the muzzle, near the tusks, is a large tubercle, supported by a bony 
prominence, which imparts a singular physiognomy to the animal. It inhabits Madagascar and 
the south of Africa 
THE BABIEUSSA. 
The Babikussa, S. bahirussa, has rather slender, long legs, and is of a grayish color above, 
with a tint of fawn below. The upper tusks come through the skin of the muzzle and turn cir- 
cularly backward, the points sometimes reaching the skin again in their downward progress. 
These are useful only for warding off the bushes ; the lower tusks, which are long and turn back- 
ward, are powerful weapons of defense and offense. This species is found in the island of Borneo, 
as well as some other islands of the Indian Archipelago. 
Genus PHACOCHQERUS : Phacochoerus. — This includes two species called Wart-Hogs, 
which have some resemblance of form to the hippopotamus. They are more exclusively herb- 
ivorous than the ti-ue hogs ; they have enormous heads, broad snouts, and large tusks directed 
upward. The feet and legs are like the true hogs. 
The Haraja or IIallup, or ^Elian's Wart-Hog, P. uEliani, is a native of ISTorth Africa, 
Kordofan, and Abyssinia. The skin is of an earthy color and scantily bristled ; a mane of thin 
hairs, ten inches long, extends along the neck and between the ears. The eyes are small ; the 
tail is nearly bare, thin, and tufted at the end. There are two skinny warts, one small and the 
other larcce, on each cheek. Hence the popular name of the animal. 
The Cape Wart-Hog, Black Bark, Valke-Vark, or Emgallo, P. JEthiopicus^ resembles 
the preceding, but the warts are larger, and the head still more uncouth in its form. Specimens 
of this have been in the Zoological Gardens of Antwerp and London. 
Genus DICOTYLES : Picotyles. — This includes the only indigenous kinds of swine of Amer- 
ica, the common hog having been unknown on this continent until it was introduced by Europe- 
ans. The peccaries have the canines in the ordinary manner, and not protruding from the mouth 
in the form of tusks; the incisors and molars are similar to those of the common hog; two great 
peculiarities of the genus are a glandular opening on the loins, secreting a fetid humor, and an 
entire destitution of tail. There are two species. Both resemble the common hog in their form, 
structure, habits, and propensities. Their gait is almost precisely similar ; they root in the earth
