Diagnosis. Rostrum not reaching end of antennular peduncle, with 5–8 dorsal teeth away from apex, 1–4 ventral teeth, usually slightly convex dorsally but may be more or less straight. Second, third segments of antennular peduncle with spine each, first segment with dorsal spinules, stylocerite reaching at least to second segment. Third maxilliped, pereopods 1–3 with epipods. Pereopods 3–5 slender, with simple, slender dactyls bearing minute spinules. Merus of pereopod 3, with 4 or 5 spines; pereopod 4, with 4 spines; pereopod 5, with 2–4 spines. Pleura of abdominal somites 1–3 rounded, 4, 5 with posterolateral points. Telson with acute apex, 3 pairs dorsolateral spines. Male total length 23 mm, female 32 mm.

Color in life. Drab brown or gray, with pale bands ( Jensen 1995). Banded with dark pigment, giving purple color. The color notes are from shrimp from Redondo Beach, California.

Habitat and depth. On sand, low intertidal zone to 104 m (Velero III station 1131-40,

LACM) but usually at 10–100 m. May be found among sand dollars, Dendraster excentricus (Eschscholtz, 1831) .

Range. Sheep Bay , Alaska to Todos Santos Bay, Point Abreojos, Rosario Bay, Baja California; Melpomene Cove, Guadalupe I., Mexico. Type locality San Francisco, California .

Remarks. The holotype of Heptacarpus herdmani bears a strong resemblance to H. stimpsoni and may be a malformed individual of this species. The rostrum is of the same length but is not dorsally convex. The dactyls of the posterior pereopods are simple, not bifid and strongly spined. The holotype is broken and shows indications of dehydration.
