Diagnosis. Carapace smooth, front not produced, with 3 median teeth. Carapace widest at anterolateral tooth 8, 11 anterolateral teeth present. Merus of third maxillipeds with distal margin nearly transverse, angles rounded. Chelipeds may be slightly unequal in size. Carpus of cheliped with single spine above, carpus, palm bearing faint ridges, movable finger smooth. Pereopods 2–5 stout, usually setose. Juveniles may be more setose than adults. Male carapace length 61.7 mm, female to 54.1 mm.

Color in life. Dark reddish above, yellowish with red spots below. Fingers of chelae dark. The color notes are from crabs from Moss Beach, San Mateo County, California .

Habitat and depth. Under rocks set in sand, tide pools, among sea grasses, breakwaters, rocky reefs; intertidal zone to 40 m.

Range. Coos Bay, Oregon to Todos Santos Is., Baja California. Reports from British Columbia are unconfirmed. Type locality San Francisco Bay .
