Material.

Internal mould of a left valve from the lower member at Langza (SNSB-BSPG 2020 XCIX 15).

Description.

Disc subovate, smooth, poorly inflated. Length 21.7 mm, height>25 mm. Auricles well demarcated from disc, only partly preserved, anterior auricle apparently larger than posterior one. Anterior, posterior, and ventral margin forming a semi-circle.

Remarks.

The specimen can be referred to Entolium (E.) corneolum without doubt, based on its outline, even though no shell is preserved. Left valves of E. corneolum, E. lunare (Roemer, 1839), and E. orbiculare (J. Sowerby, 1817) are very similar, but differ with respect to stratigraphic and/or geographic distribution (Johnson 1984).
