Diagnosis. Subtrigonal, concavo-convex rhynchonellitbrm shells, with median 

 fold and sinus well developed, and surface more or less strongly plicated. Beak 

 sharp, incurved ; deltidial plates in an incipient condition, often wanting.

 spondylium which, in the umbonal region, rests upon the bottom of the valve, 

 but anteriorly is supported by a vertical median septum. The spondylium is
