Pediohyus ferus. Type specimen i nat. size. 



There is no upper premolar 1, the interval behind the canine 

 occupying 15™'". The second premolar is small witli a sing'le 

 primary cusp near the front and a smaller one behind. The 

 third premolar is wider and has two anterior cusps which are 

 higher and stouter than the small ones on the back of the 

 crown. The fourth premolar is distinctly molariform, though 

 distinctly smaller than any molar and having but three distinct 

 cusps, the two anterior and the outer posterior one, the inner 

 posterior cusp being replaced by a low ridge (very like a strong 

 cingulum). All these pi-emolars are much less progressive 

 than the corresponding teeth in the modern Tayassu. 



The molars have low quadratical crowns and have been so 

 much worn that the details are not now clear. Each seems to 

 liave had four primary cusps, and tlie cingulum as well or bet- 

 ter developed than in the recent genus. 



The inci.sors of the lower jaw are simple and normal except 

 that the third one is less reduced than in the recent peccary. 

 Ti)e canine is a powerful tooth, which in the type specimen is 

 much worn and beveled on the anterior face. The first pre- 

 molar is wanting, the second being separated from the canine 

 by a diastema of aS""'". Judging from the alveolus, tiie tooth
