NO. 2 HARTMAX : OlANTITATIVE SURVEY 337 



5. Sta. 2426 (no. 226), in 270 fms. OPCt took 1.0 cuft of dark 

 green niiul, with siliceous sponge, tesselated small sponge, foraniiniferans, 

 and many animals. Largest species was Thclepus setosus with commensal, 

 Lepidasthenia virens ; none was outstandingly abundant. The sample con- 

 tained also a small, smooth anemone, crustaceans with eight amphipods, 

 a caprellid, five isbpods, a tanaid, three cumaceans, an ostracod, and a 

 galatheid crab. 7 otal number of species exceeded 45, and specimens more 

 than 100. Species are those usually found on slopes, characterized by 

 siliceous sponge, the ophiuroid, Sclcrasterias heteropaes, the galatheid 

 crab, and polychaetes, Thelepus setosus, Onuphis vcxillnria, Potamethus 

 mucronatus, and others. 



White Cove- Long Point 



1 Wo samples from White Cove, taken from shore and by shallow 

 diving, numbered 1370 and 1378 in the Velero series (Fraser, 1943, pp. 

 338, 359) were useful in disclosing the presence of an unknown scalibreg- 

 mid, found only in the holdfasts of Eisenia arborea; the occurrence of 

 this species was verified by recent samples from the same locality, taken 

 by Mr. Robert (7iven. The species is described as SclcrochcUus ac'irrntus 

 (see above) . 



1. Sta. 2152 (no. 224). 0.8 mi S of Long Ft., in 19 'fms. OPG took 

 0.85 cuft of sandy mud with many small animals. Only the polychaetes 

 have been analyzed (see chart) ; these number more than 37 species and 

 362* specimens. The most abimdant were Paraonis gracilis with 50, 

 Prionospio nialnigrcni with 42, Litinbrincris spp. with 43, Aricidea spp. 

 with 32, and Odontosyllis phosphorea with 31 specimens. 



2. Sta. 2450 (near no. 224). Near White Cove, in 30-35 fms. Sigs- 

 bee trawl took a large sample from a rocky bottom with sand. Largest 

 individual was a sponge, (jcodia inesotriacna Lendenfeld, measuring 90 

 mm across; also present were coelenterates, (Jorynactis, Stylntula and 

 solitary corals; bryozoans of several kinds; a polyclad, and dead Lnqiictis 

 shells. Crustaceans included amphipods, isopods, ostracods, a few epine- 

 balians, Scdlpelliini, Eiipagurus in dead Bursa shells, and two large spider 

 crabs; also an ascidian with tough tunic. V\\q fauna is that characteristic 

 of a rocky, shelly bottom. Dcndropoma lituella (vermetid) was repre- 

 sented by nvmierous colonies, and Saxirava arctica burrowed in sponge 

 and rocks. Octopus apotlyon was represented by a large male and female; 

 Bursa ccdifornica, dead shell, contained a large hermit crab with com- 

 mensal polynoid, I Icdosydna latior. The fauna is large, diversified, asso- 

 ciated with a rocky, shelly bottom.
