15. Sta. 3051 (no. 42). 2.4 mi off Pt. Fermin light, in 11-12.5 fms. 

 Biol, dredge with tangles, took large quantities of Chaetopterus with asso- 

 ciated animals. In addition to those on the chart, crustaceans were rep- 

 resented by a few Heterocrypta, amphipods, isopods. The most conspicu- 

 ous animals were Chaetopterus, Diopatra ornata and Ophiothrix spic- 

 iilata. 



Sub 15. Sta. 2473 (no. 27). 0.75 mi SE of Pt. Vicente light, in 16 

 fms. OPG took 0.75 cuft of coarse sandy mud, shell fragments, and 

 Chaetopterus with Ophiothrix (see Hartnian, 1955: 53). 



Sub 15. Sta. 2962-54 (near no. 42). 1.5 mi W of Pt. Fermin light, 

 in 20 fms. Biological dredge took black mud with Chaetopterus, large 

 Stylatula, Listriolobus pelodes, sipunculids. Modiolus and a few other 

 pelecypods, also many polychaetes. Echinoderms and crustaceans were 

 nearly absent. 



16. Sta. 3049 (no. 42). 2.1 mi from Pt. Fermin light, in 23 fms. 

 OPG took a small volume of black mud with dead shells of Lima, Modi- 

 olus, Solen, Polinices, Olivella, Pecten, scaphopod and caecid shells. The 

 sample contained Stylatula (4, very long), a ceriantharian (2), poly- 

 clads (10), few amphipods and cumaceans, and others listed on the chart. 

 The largest individuals were Stylatula and ceriantharian. Most abun- 

 dant were (Japitella capitata subsp. (985), Dorvillea articulata (700*), 

 and J mpharete arctica (200*). 



17. Sta. 4803 (no. 27). 1.6 mi from Pt. Vicente light, in 24 fms. 

 OPG took 2.2 cuft of black detrital flocculent debris with foul odor. The 

 sample contained large Stylatula (6), measuring to 50 cm long, a large 

 Cerehratulus rubra, and smaller nemerteans, a caprellid (3), and other 

 species shown on the chart. Most abundant species were Dorvillea articu- 

 lata (100*), Lumbrineris pallida (20*), Phyllochaetopterus limicolus, 

 and T haryx spp. (70*). 



18. Sta. 5096 (near no. 28). 2.5 mi from Pt. Fermin light, in 25 

 fms. OPG took 1.57 cuft black silt with manv small animals. A sea
