as typical of the animal. The lower jaw contains 

 only three back teeth. The two anterior ones 

 are formed like the upper ones, with two and four 

 roots ; and what we mentioned with regard to the 

 posterior or fourth back tooth at the upper jaw, 

 is perfectly applicable to the third or posterior 

 one of the lower jaw. 



From the above remarks on the teeth of the 

 Wart Hog, we are led to the following conclu- 

 sions : 1st, That the species examined by us, is 

 at all ages provided with incisors in the upper 

 and lower jaw ; and therefore, in the most marked 

 manner, distinguished from the species found at 

 the Cape. An additional mark of distinction is 

 mentioned by Fred. Cuvier, who says, that the 

 Wart Hog at the Cape has in its upper and 

 lower jaw only three back teeth ; whereas the 

 species examined by us constantly presents four 

 in the upper jaw. But we hesitate in admitting 

 this latter mark of distinction to be of much 

 weight ; because, as was stated above, the anterior 

 back teeth are disposed to decay, and the alveolae 

 which contained the teeth are filling up, which 

 might have well occurred in the case of those 

 very animals which were examined by Frederick 

 Cuvier. 2d, That the formation of the back 

 teeth of the genus Phascochaeres occurs in a two- 

 fold type ; we must adopt one regarding the 

 formation and manner of nourishment for the
