The shell colour is various combinations of white, cream, shades of brown, red and ochre arranged in blotches or intricate zig-zag lines. The posterior beaks on the keeled jugum of valves ii to vii have been eroded on this specimen. Frequently, but not always, approximately triangular patches on the jugal areas have lighter colours. Valves ii, iv and, less consistently, vii often have more dark colour than the other valves.
