8. Sta. 3050 (near no. 28). 2.1 mi west of Pt. Fermin light, in 10-11 

 fms, dredged, in rocky and mixed bottom. Gorgonian corals {Leptogor- 

 gia hebes) were most conspicuous; other species are listed on the chart. 



9. Sta. 2472 (no. 28). 2.25 mi E of Pt. Vicente light, in 11 fms. 

 OPG took 0.63 cuft of coarse black sandy mud with broken shells and 

 many animals. In addition to those shown on the chart, the sample con- 

 tained a few small anemones, several kinds of nemerteans, Glottidia 

 albida (1), and few crustaceans (amphipods, caprellids, ostracods, and 

 Heterocrypta occidentalis) . Echinoderms were absent. 



10. Sta. 5102 (near no. 28). 3.35 mi from Pt. Vicente light, in 11 

 fms. OPG took 0.25 cuft of coarse black sand, with tubes of Chaetop- 

 terus. A ceriantharian (2), a polyclad (6), at least two kinds of nemer- 

 teans (21), a sipunculid (4), an oligochaete (30''), caprellids (100*), 

 an amphipod (1), and Heterocrypta occidentalis (2), were present in 

 addition to those listed in the chart. The largest species was Polinices; 

 the most conspicuous Chaetopterus variopedatus (65) ; the most abun- 

 dant Dorvillea articulata (550*), Sphacrosyllis calif orniensis (100*), 

 Paraonis gracilis (85*), and Lima dehiscens (41). Echinoderms were 

 nearly absent. 



Numbers of species and specimens totalled :

others 8 64* 



Total: 87* species, 4448* specimens 



Sub 10. Sta. 5101 (near no. 28). 1.85 mi from Abalone Cove, in 11 

 fms. OPG took 0.88 cuft of coarse gray-black sand with many animals. 

 Screenings consisted of large clumps of (Jhaetopterus variopedatus with 

 Lima dehiscens, a tubicolous ceriantharian, nemerteans of several kinds.
