Contour: Rostrate.

Sculpture: Prominent, well defined, regularly-spaced raised concentric ridges, more prominent and raised near the outer margins, also very fine, widely spaced radial lines. Margin: Smooth. Ligament: Internal, opisthodetic, with a rounded triangular ligament seated in a well-developed resilifer. Hinge: Taxodont: relatively solid, continuous hinge plate, anterior part curved (convex), narrow below the beaks, broadening towards the anterior end. Posterior part long and concave. Hinge plate with a well-developed resilifer. Teeth chevron-shaped, moderately long and pointed, usually 15-18 posterior and 18-20 anterior of the resilifer.
