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 laminse. 
As remarked by Xewton, this imperfectly known species appears 
to be intermediate in its dentition between Ischyodus and Eda¬ 
phodon.
