Sculpture: Fine concentric lines and growth ridges which are very close together on posterior margin and feel rough. LV feels smooth to the touch whereas RV feels rough. Margin: Smooth. Ligament: Prominent, sunken, dark brown band extending less than a third the way to the posterior margin. Hinge: 2 cardinals in each valve. In LV anterior bifid, posterior weak. In RV posterior bifid. 2 laterals in RV, anterior short but prominent, posterior small, below nymph plate. 1 short posterior lateral in LV. Pallial Musculature: Pallial sinus deep, extends upwards two thirds of the way up to below the umbonal region and then slopes downward posterioventrally.
