Dc^'rijiHon. — Anterior teetli iiuicli compressed, the inner face ^vith. 

 fainter, more wavy and niore interrniited stria? than those of 0. eUgans. 

 Tv])ical lateral teeth much compressed, crown with sharp cutting edges 

 and a faintly striated inner face; outer coronal face gently convex. A 

 single pair of large and broad lateral denticles, usually rounded, but 

 sometimes obtusely pointed. 



This species is tolerably abundant in the Eocene of various localities 

 in Maryland and Virginia, especially at Liverpool Point on the Potomac 

 river. The lateral teeth rarely exceed 2.5 cm. nor the anterior 3.5 cm. 

 in total height.
