Beaks located one-quarter shell length from anterior, strongly opithogyrate. Anterior sharply rounded; shell medially sulcate. Posterior umbonal ridge on left valve sharp and forming a 90° angle, passing at angle of 35° from dorsoventral axis towards posteroventral margin. Posterodorsal margin deeply depressed, flattened. Posterior umbonal ridge on right valve less angular, posterodorsal area less depressed. Radial sculpture of about 40 ribs anterior to posterior umbonal ridge, generally with every other radial rib inserted below umbonal area; about 20 radial ribs posterior to posterior umbonal ridge, generally equal in size. Radial ribs cancellate when crossing commarginal growth lines. Cardinal area narrow, smooth except ligamental area; full length not preserved. Ligamental area broadly triangular, includes entire cardinal area anterior to umbones; scored by at least 16 vertical ridges. Hinge plate not preserved. Ventral margin not preserved.</paragraph>
