Description

Shell inequilateral, elongate, inflated to compressed, usually equivalve. Shell weak without external sculpture except for weak radial ribs or furrows. Periostracum dominating shell, thick, varnished, extending beyond shell. Umbones not prominent, near posterior end. Hinge plate weak, edentate; ligament opisthodetic, internal, with or without supporting buttresses. Posterior adductor scar small; anterior scar large, continuous with oblique pedal retractor scar.
The features used to differentiate the three living subgenera of Solemya include the presence or absence of lateral buttresses supporting the shallow resilifer, and the presence and extent of the subumbonal uncalcified area covered by lobes of the ligament. The function of this organic break in the shell is not known, but it may permit twisting of the valves in a fashion similar to the slit in the shell of certain members of the family Periplomatidae. Two subgenera are represented in the northeastern Pacific. The genus is known from the Jurassic. The name is derived from the Greek solen, a pipe, and the latin word mya, a sea mussel, and is feminine.

Small shells. Compressed. Equivalve. Inequilateral, beaks near the posterior margin. Outline elongate oval. Hinge lacking teeth, ligament behind the umbos external or partly internal with chondrophore. Sculpture with weak radial lines, periostraeum overlapping shell margins.
