This oval one and one-quarter inch chiton has rather elevated valves. The surface is lusterless and is a rather dull and dingy olive or olive-green marked with black along the jugal and on the sides of some valves. The lateral areas are moderately raised and sculptured with 2 or 4 rows of distinct tubercles. The central areas have strong, irregular growth wrinkles and fine longitudinal riblets. The girdle is wide, color alternating light and dark with rather large scales.
