SUMMARY,- The animals are largely polychaetes of snialle:^^inds. The 

 volume of organic materials -is about 100 ml. . 



1 W-3o Sta, 3483-55. In 58 feet. OPG took 1.8 cuft of black 

 mud with sticks, 



Echinoderms include 9 smaller ophiuroids, a very small asteroid and 



2 moderately large Astropecten californicus 

 Coelenterates- a few small^, resembling Harenactis (anemone) 

 Brachiopod- Glottidia albida - 1 smaller' only 

 Crustaceans include 2 caprellids and 13 or more amphipods 

 Polychaetes include larger individuals of: 



Nephtys ?caecoides -l 

 Nothria elegan s- 3 



Phylloch a etopterus prolif ica - 1 in tube 



and smaller individuals of: Chaetozone , ExMiida, Goniada, Haplo - ' 

 scoloplos , Laonice ;, Lumbrlneris , maldanids, Nephtys , Nereis , 

 paraonids, Pherusa , Phyll od oce , Prionospio , Syllis , Tharyx, 

 and others. 

 SUMMARY.- The representatives of these species are smaller in size 

 than those more remote from the outfall, and represented by 

 fewer individuals. Their volume is about 115 ml. The largest 

 individual is Nephtys caecoides , the most conspicuous is Nothria 

 elegans .

 black mud with HgS odor. The screenings consisted of much biological 

 debris^ especially algal bltS;, broken tubes and a few shelly frag- 

 ments, in all about half a liter,

 SUMMARY,- This sample is characterized by its preponderance of poly- 

 chaetes. The largest individual is Glycera americana , the most 

 abundant is Nothria elegans . Its voliome is estimated at 70 ml. 



I W-5, Sta, 3489-55, In 138 feet. OPG took 1.57 cuft of 

 green sticky mud with slight HgS odor. The screenings consist of 

 many arenaceous foramlniferans and much diversified life.
