This one and three-quarter inch chiton has a medium width girdle, with overlapping scales which are flat; larger at the valves and smaller at the margin of the girdle. They are deeply ridged with fine netlike sculpturing in between these ridges. There are 5-8 rows of prominent beading on the lateral areas. The end valves are radially beaded in ridges. The color of the valves is olivaceous or gray. Some specimens have dark triangular blotches on the jugum. The girdle is dark and light gray blotched.
