Palm of chela with short coarse setae, scattered granules. Dactyl setose dorsally, longer than fixed finger, with small triangular tooth toward proximal end, row of small teeth near apex of dactyl. Fixed finger with triangular tooth at middle, small teeth opposite those of dactyl. Fingers with small gape proximally when closed. Pereopods 2–5 fringed with setae, with nearly straight dactyls.Ventral margin of propodus of pereopod 3 with 6 spines, that of pereopod 4, 5 with 4 spines. Pereopod 4 longest, thickest. Dactyl of pereopod 5 extending to carpus of third leg. Male carapace length 3.3 mm, female not reported.

Color in life. Yellowish white; see color photograph by Garth & Abbott (1980: fig. 25.40).

Range. Monterey and Pacific Grove, California. Type locality Monterey Bay , California .

Remarks. Weymouth (1910) did not seem to know that Rathbun (19893) had used the name Pinnixa californiensis . That name now is considered to be a junior synonym of Pinnixa occidentalis . Garth & Abbott (1980) gave the only figure of this species that was based on a specimen other than the type material.
