Thick shell, with beaks just in front of the midline, and almost circular in outline, up to 39 mm long. The outside is a light brownish white and the inside is white. There is no pallial sinus but there is a complete pallial line. The outside is sculpted with irregularly spaced concentric grooves, but the growth lines are not obvious. The ridges are prone to erosion.
