panied by sea urchins (5), many small mollusks, numerous small crus- 

 taceans, and many diversified polychaetes, some not recovered elsewhere. 



Sta. 2173, in 252 fms. OPG took 1.57 cuft of mud, with a nemer- 

 tean, brissopsid urchins (2), a few ophiuroids, a small crustacean, and 

 polychaetes including some not found elsewhere; they include Anaitides 

 sp. ; Glycinde polygnatha; Lepidasthenia virens; Lumbrineris index; 

 Oncoscolex pacificus; Prionospio sp. ; Scalibregma inflatum ; Thelepus sp. 



Sta. 2172, in 517 fms. OPG took 2.52 cuft of fine green mud with 

 glass sponge, disklike foraminiferans, and animals differing from those in 

 shallower depths. The largest individuals were a philinid mollusk (1), 

 and a tube of Ma/dane, with lateral branches, measuring 30 mm long 

 by 5 mm wide. Other animals were a pelecypod (3), an amphipod (1), 

 an ovigerous isopod (1), and polychaetes: Aricidea sp., Chaetozone sp., 

 Drilonereis sp., Laonice sp., Lumbrineris index (1), Alaldane sp. with 

 branched tube (4), Ninoe sp. and Thnryx hnultifilis (3). 



Sta. 2170, in 587 fms. OPG took 2.9 cuft of fine mud with glass 

 sponge spicules, many foraminiferans, and few animals. 1 hey were poly- 

 chaetes with Aricidea uschakowi (several), Onuphis sp. (1), Lumbri- 

 neris ?index ( 1 ) , a harmothoid ( 1 ) , a terebellid ( 1 ) ; a small pelecypod 

 and amphipods (few). 



Palisades 



1. Sta. 3610, in 20.5 fms. OPG took 0.5 cuft of gray muddy sand 

 with black algal detritus, little sand and gravel, and many animals. Most 

 abundant and conspicuous was Glottidia albida (50 large, measuring to 

 27 mm long, and 4 small, only 9 mm long). In addition to the species 

 named in the chart, there were a small ceriantharian (3), a large Cere- 

 bratulus rubra ( 1 ) , ectoproct bryozoans, crustaceans with an amphipod 

 (2), a cumacean (1), a spider crab (1 jv), a box crab (1 jv), and 

 a pinnotherid crab ( 1 ) .

2. Sta. 3609, in 34.5 fms. OPG took 1.07 cuft of gray mud and fine
