Carapace with antennal tooth, pterygostomian margin produced forward into blunt knob, carina running posteriorly from antennal tooth, grooves posterior to orbit and near hepatic spine. Stylocerite longer than eye. Scaphocerite with tapered apex. Third maxilliped with long exopod, pereopods with exopods. Pereopods 1–3 chelate, pereopods 4, 5 with simple dactyls. Pleura of abdominal somites 1–5 blunt, that of somite 6 with posterodorsal and posterolateral points, part of abdominal somite 4 and all of abdominal somites 5, 6 with dorsal carina. Telson shorter than uropods, with dorsal groove. Total length 88–201 mm.

Color in life. Rose brown, sometimes with dull brown vertical stripes on abdominal somites.

Range. San Francisco Bay , California to Callao, Peru, but uncommon in California. Type locality Anaheim and San Francisco bays, California .
