Ventral muscle field extends to posterior over the hinge line. Lateral apical cavities are almost completely filled by secondary shell material and not extending to posterior over the hinge line. A small septal pillow is developed dorsal of the ventral muscle field. Both sides of the septal pillow are bordered by a thin subdeltidial furrow on the internal mould of which only one is preserved. Ventral process weakly developed leaving a very small groove on the internal mould from the septal pillow to the beginning of the ventral myophragm. The myophragm is thick leaving a broad furrow through the posterior half of the ventral muscle field on the internal mould. The ventral muscle field is broad, elongated, almost diamondshaped in outline, and deeply impressed into the shell. On each side, 2 costae are gently impressed on the internal mould of the ventral muscle field. Diductor scars are impressed as subradial striae on the internal mould. Adductor scars situated next to the myophragm and enclosed completely by the diductor field; posterior and anterior pairs clearly differentiable and clearly impressed into shell. The anterior part is lancet-shaped and broad, the posterior part elongated and thin. Muscle bounding ridge broad and clearly developed, leaving a deep furrow on the internal mould as the lateral border of the ventral muscle field. Anteriorly, in the sulcus, the muscle bounding ridge is only weakly impressed. Free portions of dental plates short, leaving small wedge-like slits on either side of the ventral muscle field on the internal mould. Posteriorly they are imbedded into secondary shell material. Its anterior parts pass into the muscle bounding ridge. No teeth preserved. Due to the strong development of secondary shell material, a platform is formed on both sides of the ventral muscle field which is covered by numerous gonoglyphs preserved as tubercles on the internal mould. Sulcus smooth, conspicuous, and shallow, at base flattened in cross section. Each flank of the specimen is covered by 6 coarse and simple costae that are impressed anterior of the platform on the internal mould. The sulcus bounding costae are slightly weaker than the adjacent pair of costae and included into the sulcus. No impressions of growth lamellae.</paragraph>

It is angular in cross section and with steep flanks. The sulcus tongue is long to short, its outline at the anterior margin is rounded to angular.

The first pair of costae is included into the sulcus and also more weakly developed than the second pair. The external dorsal valve is covered by one or two costae less than on the ventral shell. In some cases, the first pair of costae is situated on the flanks of the fold. The costae on both valves are coarse, simple, do not multiply by bifurcation or intercalation, and are angular in cross section. They are separated by furrows that are angular in cross section and of the same size as the costae. At the anterior margin, coarse and concentric growth lamellae are developed. The edges of the growth lamellae overhang on the next younger lamellae.</paragraph>

A). A broad myophragm originates from the ventral process leaving a distinct furrow through the first half to two thirds of the ventral muscle field on the internal mould. The ventral muscle field is broad and generally elongated, always slightly longer than wide; subelliptic to rarely diamond-shaped in outline. Two to three costae are weakly impressed on the internal mould of the ventral muscle field. Diductor scars leave subradial striae on the internal mould. Adductor scars elongate, posterior and anterior pairs clearly differentiable, and situated admedian next to the myophragm. The posterior pair of adductor scars is thin and elongate. The anterior pair is elongate and lancet-shaped. Both pairs slightly imbedded into the shell. Muscle bounding ridge strongly to weakly developed leaving a fine to coarse furrow on the internal mould starting at the anterior end of the dental plates and diminishing towards the sulcus. Free portions of dental plates moderately short and knob-like, situated on the lateral border of the sulcus and leaving divergent broad slits on the internal mould. Even in juvenile specimens, dental plates are already imbedded into secondary shell material, in adult specimens they sometimes leave only a small indentation on the internal mould.
