Dinichthys intermedius ? Newberry 



E 2033 A pair of rather small mandibles (fig. 6), associated with 

 several fragmentary Dinichthys plates, in outer view, on 

 a slab of shale. The mandibles measures 17.5 cm. in 

 length, and 6 cm. in height (at the beak) ; and the beak of 

 the right mandible overlaps that of the left. The cutting 

 margins are not weU preserved, but can be made out for 

 their entire length; there are no denticles preserved 

 on the posterior portion of the functional margin.
