| G. A. Cooper 1956 | Shell small, wider than long w^ith hemipyramidal pedicle valve. Surface multicostellate, the costellae crossed by elevated concentric plaits (lamellae). On the brachial valve the posterolateral areas are conspicuously marked by the concentric lines. Pedicle valve v^ith broad shallov^^ sulcus extending from beak to anterior margin ; flanks rounded. Areas between flanks and posterior margin concave. Spondylium broad and shallow with the characteristic median depression flanked by narrow, elevated tracks. Median septum short.
Brachial valve slightly concave in the posterior half but slightly convex in the anterior half. Sulcus widening rapidly from the beak to the anterior margin where it occupies about one-third the width. Anterolateral flanks gently convex; posterolateral areas flattened. Brachial interior with strong anteriorly widening median ridge corresponding to the sulcus. Median ridge much elevated and thickened anteriorly. Cardinalia much thickened. |
