Coarse costellae changing distally into broad, poorly defined radial undulations covered by fine costellae. Low filae and infrequent strong growth lines also present. Finer costellae impressed on distal 35% of valve floor. Strong costellae impressed throughout valve floor.

Ventral interarea planar and apsacline, tending toward catacline, about 20% as long as valve. Valve interior not exposed, but wetting the largest specimen provided some information. Muscle field raised above valve floor, especially in front. One broad central and two narrow lateral ridges, all very short, extend slightly anterior to muscle field. Muscle field about 25% as long as valve. Tracks of dental plates bordering muscle field first diverge, then begin to converge and finally diverge slightly again.</paragraph>
