The ventral margin is straight, with the wall thickened in areas halfway between the center of the valve and the ends. The dorsal margin is convex. The dns are not disctinctly formed, but confluent with the rest of the valve. The terminal nodules are distinct, near the ends of the valve. The striae are parallel(Patrick and Reimer 1966).
