NO. 2 HARTMAN : QUANTITATIVE SURVEY 253 



Analyses. Some of the crustaceans are more completely named in the 

 State report (California. 1965, App. pp. 104-301). 



1. Sta. 2741 (no. 50). Ofi Seal Beach, in 5 fms. Campbell grab 

 took 2.15 cuft of red-brown beach sand with broken shells. The fauna 

 was a limited one, comprising chiefly three species of polychaetes (see 

 chart), two echinoderms, and two mollusks, each in considerable 

 numbers. 



2. Sta. 4885 ( no. 49) . 2 mi from east end of Long Beach breakwater, 

 in 6.5 fms. OPG took 1.89 cuft of red sand over grayish black silt. In 

 addition to the species listed on the chart, there were a small anemone, 

 a polyclad (3), nemerteans (21), a phoronid (1), Glottidia albida 

 (1), 11 kinds of amphipods (26), two cumaceans (5), three ostracods 

 (6), a pinnixid crab (3), a shrimp (1), a pycnogonid (7), Branchio- 

 stoma sp. (22), and an enteropneust (3). Largest species was Solen 

 stearins, and most conspicuous Branchiostoma. Most numerous species 

 were Mediornastus calif orniensis (125), Tharyx tesselata (113), Prio- 

 nospio pinnata (61 ), and Arnphipholis squamata (52). 



Numbers of species and specimens totalled : 

 polychaetes 45 species, 619 specimens 



echinoderms 4 64 



mollusks 7 9 



crustaceans 20 44 



others 9 64 



Total : 85 species, 800 specimens 



3. Sta. 5740 (no. 68). 9.75 mi from Los Angeles harbor light, in 8 

 fms. OPG took 0.06 cuft of fine gray sand. In addition to those named in 

 the chart, the sparse sample yielded a small coelenterate, two nemerteans 

 (9), bryozoans, eight amphipods (33), two cumaceans (9), a Callia- 

 nassa sp. (4), and a crab (2). Largest species were Terebra pedroana 

 and Ophiodertnella incisn; most abundant were Chaetozone corona (65), 

 Tharyx tesselata (51), Prionospio inalmgreni (46) and P. pinnata 

 ( 42 ) . and OlivcUn hncticn (31).
