 fine radiating costfe which become obsolete at the sides ; hinge area 

 straight, ligament pit broad, not deep ; auricles small, slightly 

 produced, nearly equal in size. 



It is rather remarkable to find this Eocene species still living, 

 but, on comparing examples of each, the differences observed are 

 certainly not sufficiently important to warrant specific separation.
