Diagnosis. — With the characters of the genus. 



Description. — Rostrum absent, lateral cephalic lobes obsolescent, 

 side of head slightly convex, truncate, scarcely invaginated at antero- 

 ventral corner; eyes absent; epistome rounded- truncate anteriorly; 

 gnathopod 1 of the melita form, palm nearly transverse; gnathopod 

 2 of male larger than that of female, article 5 stouter and shorter 

 relative to article 6, rounded but not distinctly lobed posteriorly, 

 densely setose, article 6 nearly twice as long as 5, scarcely broader 

 than 5, palm and posterior edge of article 6 confluent, densely setose, 

 mediodistal face armed with 2 rows of 4 and 5 spines respectively, 

 palm poorly defined by 2 medial spines, medial surface armed with 

 bundles of setae marked in the accompanying figure by their bases 

 only, dactyl with small scales on inner surface; second articles of 

 pereopods 3-5 narrow; pleonite 4 with one small dorsal seta, pleonite 

 5 with pair of setae on each dorsolateral surface; uropod 2 with 

 long combs of spines on mediodistal peduncular apex; other characters 

 as in figures. 



Holotype. — AHF No. 631, ovigerous female, 4.1 mm. 



Type locality.— Station 45-T-3, November 11-13, 1962, wash 

 of roots of Phyllospadix sp. 



Material. — corona del mar: underrock substrate, scarce; Phyl- 

 lospadix-cor&Rine grid, rare (4 per sq. m.); loose rocks, rare, la jolla: 

 Phyllospadix-c orollme grid, rare; underrock grid, rare. 



Elasmopus antennatus (Stout) 



Neogammaropsis antennatus Stout, 1913, pp. 645-646. 



Elasmopus antennatus: Shoemaker, 1941b, p. 187. — J. L. Barnard, 1962b, pp. 

 88-91, figs. 12, 13; 1964a, p. 222. 



Adult males from Carmel station 48-H-6 have all characters of 

 E. antennatus, including those of gnathopod 2, the telson, uropod 3, 

 and the third pleonal epimeron, but article 2 of pereopod 5 is deeply 

 serricate as in E. rapax serricatus, a subspecies described below. 



Material. — carmel: Macrocystis holdfast, scarce; tunicates and 

 sponges, most abundant species; wash of Phyllospadix roots, second 

 most abundant species (variety with serricate pereopod 5). cayucos: 

 Phyllospadix-pelvetM grid, abundant (695 per sq. m.); Macrocystis 

 holdfast, rare; new growth of brown alga, most abundant species.
