foramlnlferans^ especially Buliminidae, The silt was unusually colored 



reddish brown or coffee colored when washed.

 Amphiodla urtica - 7 Spatangus californicus - 1 



Ophiura liitkeni - 2 holothurian - 1 juvenile

 Phoxocephalld amphlpod, Pontharpinia sp. J-2 



Mollusks include diversified smaller pelecypods and gastropods, 

 with Tellina and Acila . 



Echiuroids Thalassema - 1 larger 



Polychaetes includes 



Aricidea laonlce 



smaller capltelllds Paraonis 



Chloeia pinnata - juveniles Pherusa capulata 



clrratulids Pholoe 



Glycera - juvenile splonids, smaller kinds 



Goniada Tharyx 



Isocirrus and others 



SUMMARY," The largest animal is Thalassema , the most conspicuous are 

 various kinds of polychaetes. The estimated amount of organic 

 matter is 125 ml, 



I W=-19a, Stao 4321-56. In 257 feet. OPG took 0.75 cuft of bedded 

 mud-stoneo The screenings consisted of about a liter of materials, 

 with considerable fine coffee-colored silt, tiny mud balls, a larger 

 ghost shrimp J and other animals weighing not over 10 grams. 

 Echinoderm: a larger Ophiothrix spiculata 

 Crustaceans include a ghost shrimp, some amphipods, brown ostracods 



and cumaceanso 

 Polychaetes include juvenile Chloeia , Glycera , small Lumbrineris , 



Nephtys and others. 

 SUMMARY.- The animal contents were few in quantity and aiversity. 



I W-=19b, Sta. 4320-56, In 492 feet. OPG took 1.26 cuft of sticky 

 green sllty mud. The screenings consisted of a little over a liter 

 with much shelly coral and other calcareous debris, especially old or 

 bleached fragments of Allopora (hydrocoral) , tube fragments and other 

 biological rubble. The animal population is diversified. 

 Echlnoderms include some smooth red ophiuroids 

 Mollusks Include smaller shells of Axionopsis , a tiny Dacrldium, 



caecids, and others 

 Monobrachium j a coelenterate, is fairly abundant 

 Polychaetes Includes 



Pectinaria callforniensis - 50 to 75; the largest measure 43 mm long 



a giant capitellld 

 SUMMARY.- The largest animal is a capitellid, the most conspicuous is 



Pectinaria . The bottom appears to have been earlier populated 



by a hydrocoral association and more recently replaced by a mixed 



fauna.
