SKULL OF THE ETHIOPIAN WART HOG.
ETHIOPIAN WART HOG.
The dentition of the Peccary differs from that of the True Hogs in the smaller number of teeth, which are thirty-eight, instead of forty-four, in number, the upper incisors being reduced to four, and the premolars in the upper and lower jaws being six instead of eight. There are also differences in the shape of the teeth, the grinders presenting transverse ridges, as may be seen from the comparison of the accompanying figure with that of the Hog.
There is also another important difference to be noted between the Peccaries and the True Hogs in the structure of the feet. In the former, the middle metatarsals and metacarpals unite into a solid cannon bone analogous to that of cattle, while in the latter they are distinct during the whole life of the animal.
