Shell medium to large, elongated and narrow. Anterior margin broadly rounded, with anteriormost extremity positioned roughly in middle of curvature. Dorsal and ventral margin parallel to subparallel. Valves of some partially articulated specimens rotated along ligament line, which gives a false impression of shell widening anteriorly. Posterior margin evenly rounded, with curvature more pronounced than that of anterior margin. Umbones weak, opisthogyrate. External ornament composed of radial ridges projecting from umbonal area towards shell margins and commarginal growth lines, preserved as weak and broad wrinkles. Radial ridges are two to three times as wide as interridge spaces. On internal moulds external radial ornament is weaker. Anterior adductor muscle scar weak and positioned close to anterior shell extremity, supported by dorsal margin. Anterior adductor muscle scar rarely preserved well enough to define shape, but when present forms a broad arch pointing anteriorly, with its posteroventral margin running dorsally, passing into oblique and elongated portion, probably representing a visceral mass integument attachment scar. Posterior adductor muscle scar well impressed, especially on larger specimens, egg-shaped, with acute end pointing towards umbo. Anterior margin of posterior adductor muscle scar supported by well-developed buttress, running obliquely in dorsal direction and connected with chondrophore. Dorsal margin of posterior adductor muscle scar supported on a chondrophore; posterodorsal margin of posterior adductor muscle scar projecting above chondrophore. Hinge edentulous. Ligament internal, supported on a chondrophore, with small ligament demipads parallel to dorsal margin anterior of chondrophore.

The external ornament of modern solemyids, especially of the thin-shelled species, is likely to be subjected to early diagenetic modification due to shell dissolution. The external shell shape and proportions can also be subjected to some variation due to plasticity and deformation of the organic-rich shell during burrowing (e.g.
