Diagnosis
ReferenceDiagnosis
R. L. Squires and L. R. Saul 2004Shell small to moderate, subquadrate to elongate ovate, inequilateral, right valve slightly larger and deeper than left. Posterior slope acutely set off by radial keel. Valves usually pointed (tapered) posteriorly. Umbones not inflated, nor set off by growth stages; beaks slightly prosogyrate. Lunule and escutcheon absent. Sculpture of weak to moderately strong commarginal ribs, similar on both valves; radial threads possibly present. Left-valve hinge with chondrophore and (posteriorly) adjoining deep pit. Chondrophore moderately broad, somewhat projecting and flattish, and bearing median ridge. Right-valve hinge with single, large triangular cardinal tooth (upcurved at tip) and adjoining deep, broad pit. Adductor scars prominent. Pallial sinus simple, short, nearly vertical, and shallow to absent (Yokes, 1945; Stenzel et al., 1957; Keen, 1969; Coan et al., 2000; Coan, 2002).
