Ornamentation unevenly costellate and faintly beaded; one to five finer costellae grouped between slightly larger ones. Region adjacent to posterior margin displaying weak oblique wrinkles in occasional specimens.

Pedicle valve moderat.ely convex in lateral profile; umbonal region gently inflated. Interior of pedicle valve finely papillose. Teeth small. Adjustordiductor muscle field wide, extending to about midlength; diductors strongly diverging in front of short median septum; paired adductor scars deeply incised into callus deposits of delthyrial floor.

Brachial valve concave in lateral profile. Inner surface marked by fine papillose elevations. Adductor muscle field large, ·subcircular in outline, reaching beyond the middle of the valve; inner scars bordered by moderately elevated septa; occasional specimens displaying low median septum. Brachiophores large, strongly divergent, and ending in points; cardinal process strongly elevated ventrally. Interarea short, anacline.
