Diagnosis. Rostrum bluntly rounded. Carapace smooth, with cervical, lateral grooves. Eyestalk without acute and divergent apex, pigmented cornea at middle of eyestalk. Third maxilliped operculiform. First chelipeds unequal, sexually dimorphic. Major cheliped of male with merus having prominent ventral lobe, carpus strongly incurved, subequal in length to hand, fingers gaping, crossing at apices. In female, immature male hand longer than carpus. Smaller cheliped with carpus longer than hand, fingers shorter than palm. Pereopod 2 chelate, flattened. Pereopod 3 with triangular carpus, broad subrectangular propodus, small rounded dactyl. Pereopods 4, 5 slender, last leg chelate. Abdominal pleura narrow. Male with vestigial pleopod 1, pleopod 2 absent, pleopods 3–5 foliaceous. Female with pleopod 1 uniramous, pleopod 2 biramous. Telson subrectangular, with 2 dorsal ribs, tooth on posterior margin. Uropods about same length as telson, exopod with dorsal ribs. Male total length 115 mm, female 120 mm.

Color in life. White to creamy, patches of pink, yellow to orange on appendages, abdomen pink ( Jensen 1995).

Habitat and depth. Mud or sand, intertidal zone.

Range. Mutiny Bay , Alaska to Todos Santos Bay, Baja California, Mexico. Type locality "California" (probably San Francisco Bay or Monterey, where Dana obtained specimens) .
