No attempt has been made to examine the hinge, as the valves are so soft that they do not survive being separated. However, the distinctive external form of the shell and the anatomy are sufficient to describe it and place it at the family level.</paragraph>

) Mantle edge mostly unfused with extensive anterior-ventral pedal aperture; fused with terminal of gill axis; exhalant aperture small. Anterior-ventral inner margin raised into series of prominent evenly spaced transverse ridges. Anterior and posterior adductor muscles of similar size, oval in section. Posterior pedal retractor and anterior pedal muscles present. Ctenidium of a single demibranch, ascending and descending lamellae of almost equal size. Labial palps small. Foot with well developed toe, sole flattened and apparently with tissue projections (these may be an artefact of preservation); heel distinct, byssus functional producing numerous thin filaments.
