 Ventral valve moderately elevated, sub-circular in outline, somewhat described. 



flattened on the cardinal slope, where, in outline, it is slightly convex ; 

 nearly straight in the anterior slope. Interior At the back there are 

 one or two faint grooves on the median part of the cardinal slope ; the 

 foraminal boss is a wedge-shaped one with the point directed forward ; 

 this is enclosed by two sub-parallel, deep, rounded pits, for attachment of 

 muscles. Behind the foramen is the back of a ridge, similar to a crescent, 

 that encloses the apical part of the shell behind, and laterally; in the
