Type. Bight mandibular tooth ; British Museum. 



Mandibular tooth robust, the beak being scarcely produced ; oral 

 margin with traces of an external thickening layer; symphysial 

 facette broad, but occupying only about one quarter of the inner 

 aspect ; beak-tritor and the anterior outer tritor laminated ; the 

 symphysial extension of the very broad inner tritor also laminated, 

 the hinder portion of this and the posterior outer tritor consisting 

 of tubules. (?) Palatine tooth with the small posterior inner tritor 

 of tubules, the outer and the anterior inner tritors larger and com- 

 posed of laminae. 



As remarked by Newton, this imperfectly known species appears 

 to be intermediate in its dentition between Ischyodus and Eda- 

 phodon.
