The skull of this species is distinguished from the skull of T.ferruginea by the 

 less elongated character of the facial portion and by its smaller size. The post- 

 orbital parietal ridge is more distinct than in T.ferruginea, and the molar perfora- 

 tion is smaller than in the latter species. The teeth are smaller than in T.ferru- 

 ginea, and the second upper premolar wants the internal cusp and the cusp on the 

 anterior margin, both of which are unmistakeably developed in the last-mentioned 

 species ; but these structures nevertheless are represented in the present species by 



* Tail imperfect.
