8. Sta. 4886 (near no. 48). 0.85 mi east of Long Beach, near break- 

 water, in 10.5 fms. OPG took 1.44 cuft of gray to black, medium to

 sea-whip ; one nemertean (32), 11 amphipods (35), two isopods (2), 

 three cumaceans (26), three ostracods (4), Callianassa sp. (1), two pin- 

 notherid crabs (19), two pycnogonids (8), and an enteropneust (7).

 ous were Tharyx tesselata (300*), Scalibregrna inflatmn (61) ,^ Aledio- 

 mastus calif orniensis (45), Amphipholis squamata (41), and Brada 

 pilosa (34). 



9. Sta. 3053 (near no. 47). 3.5 mi off Los Angeles light, in 11-12 

 fms. Biological dredge, in rocky and rubbly bottom, took a diversified 

 fauna, with a large pagurid, echinoderms, fishes, and many other ani- 

 mals. Coelenterates were present with gorgonian corals, Euplexaura 

 marki, coarse brown Eunicea, Ptilosarciis quadrangularis (broad-pan- 

 nicled sea-pen) and Corynactis calif ornica. Bryozoans were encrusted on 

 rocks, and crustaceans included many amphipods, caprellids, and barnacle 

 clumps. The largest individuals were Holopagurus pilosus, and Astropec- 

 ten sp. Number of species was estimated at more than 57. 



10. Sta. 231 1 (no. 66). Off Long Beach breakwater light, in 12 fms. 

 OPG took 0.5 cuft, in 2 drops. In addition to the species named (Hart- 

 man, 1955, p. 76) additional species are indicated in the chart. Total 

 number of species is well over 100. 



11. Sta. 6102 (near no. 47). Off Long Beach breakwater, in 12.5 

 fms. OPG took 0.63 cuft of dark gray fine sand. A polyclad (1), a 

 small nemertean (28), six amphipods (18), four cumaceans (8), two 

 ostracods (10), a mysid (1), and a pinnixid (1), accompanied the spe-
