 SUMMARYo- The sample has characteristics of an undiminished fauna for 

 having representatives not present near effluent areas. 



III"5<, Stao 3210-55. In 170 feet. OPG took 0.97 cuft of fine medium 

 green sllty sand„ The screenings consisted of about a pint, largely 

 animals., of which about half was various kinds of ophluroids, not quite 

 as much was other kinds of invertebrates, and the inert debris had many 

 arenaceous foramlniferan remains, especially Rhabdamlna and others. 

 Echinoderms include many smaller ophiuroids and a tiny asteroid. 

 Crustaceans Include; 



larger amphipods, perhaps Ampelisca - 17 



many smaller amphipods 



ostracodSi, largely brown, some rectangular white - many 



ciomaceans - 9 or more 



tanaids - 4 



Isopods - gnathld - 6, presiMiably with rhizocephalan parasite 

 anthurid - 6 



a small crabj, Heterocrypta 



parasitic copepod attached to thorax of Terebellldes . 

 Mollusks include some smaller pelecypods and gastropods, none conspicuous 

 Hydroid^ Monobrachium , on small clar

 Poiychaetes include conspicuous niimbers of Chloela, Pectlnaria , Pholoe , 



a larger Travisia , and many other kinds. 

 SUMMARYo- The sample is characterized by many different kinds of animals, 



III-60 Sta» 3206-55. In 201 feet. OPG took 0.05 cuft of fine green 

 sllty sando The screenings consisted of many kinds of smaller animals 

 totalling about 1 1/2 pints of which ophiuroids and other echinoderms 

 measured about half of the total. There were a few red waxy lumbs, so 

 light in weight as t o float in water. 

 Echinoderms includes 



many smooth disked, smaller ophiuroids, totalling about 2/3 pint 



small purple holothurolds - 6 



sea urchin - 1 small, measuring about 21 mm across the disk 



a small sea star 

 Crustaceans include t 



plnnixid - 2 small 



amphipods - about 124, with 23 larger red, and 101 smaller pale kinds 



cumaceanSj, including at least 4 species and totalling about 36 



ostracods^i including at least 3 species and ntimbering more than 70 



isopods. Including 2 anthurid, 8 Gnathia (some of which may be para- 

 sitized by a rhizocephalan), and 6 tanaids of which one is an 

 adult male and one female carries ova.
