Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. J. Ross 1971 | Shells transversely elliptical in outline, subequally biconvex in anterior profile. Brachial valve the deeper in lateral profile. Pedicle sulcus and brachial fold originate near midlength, variable in width and depth. Pedicle cardinal area of variable width, curved, apsacline; brachial cardinal area short, straight or very slightly curved, anacline. Surface marked by fine radial costellae and by fine pits. On surface, pits appear between costellae for most part, but decorticated calcareous shells show concentric rows of shallow pits crossing radial rows to form closely packed series of quincuncial patterns. Shell substance impunctate. |
