ovate, deep, strongly asymmetric, projecting from RV. Ligament large, set in deep resilifer. RV with two cardinal teeth, and a single, large anterior lateral tooth set close to cardinal teeth, posterior lateral teeth absent or indistinct. LV with 2 cardinals, anterior lateral 1 or 2, close to cardinal. Posterior lateral tiny or absent. Anterior adductor scar, long, detached from pallial line for about 2/3 of length.
