The outline is variable, from elongate oval to subpentagonal, dorsal valve often subcircular. The shell is relatively thick with a greatly thickened muscle region. The beak is erect to slightly curved, no beak ridges are observed. The pedicle opening is of medium size, permesothyrid, labiate. The symphytium is small, partly visible to nearly concealed. The lateral commissures are straight to slightly ventrally curved, while the anterior commissure is rectimarginate to slightly uniplicate in adult.</paragraph>

The secondary layer is thicker than the primary one (28- 55 µm) and made up of sheaves of fibres which are anvil-like in transverse section. The tertiary layer, much thicker than the two previous (727-790 µm), is composed of large calcitic prisms perpendicular to the shell surface. The total thickness of the shell is 817-890 µm at the observed section.
