The finely scaled girdle of this one inch chiton is rather narrow. The lateral area of the median valves is raised to prominently that it appears as a large single rib. The central area has longitudinal grooves with crosslines giving a mottled appearance. The tail valve has a highly posterior mucro with 3-6 heavy bifurcated ribs. The head valve has 7 grooved ribs. The color ofthe girdle is cream with brown bands. The valves are mottled grayish green and light brown.
