Diagnosis
ReferenceDiagnosis
L. R. Saul and W. P. Popenoe 1992Veneriform bivalves having growth lines and, generally, well-marked growth checks and a depressed lunule set off by an incised line. Hinge with three cardinals in each valve, two an- terior and two posterior lateral teeth in the right valve, and one anterior and one posterior lateral tooth in the left valve; posterior cardinal of the right valve 3b narrowly bifid; anterior lateral All long, parallel to the lunular border, and terminated posteriorly in a short, ventrally directed prong; left posterior lateral a salient projection of the posterior dorsal margin fitting into an elongate socket in the right valve bounded dorsally by the right posterior dorsal shell margin, and ventrally by elongate lateral tooth Pl. Nymphs smooth. Pallial sinus moderately deep. The anterior adductor muscle scar impressed and immediately at the anterior end of the hinge plate.
