Between China Point and Salta Verde Point 



1. Sta. 3600, in 25 fms. OPG took 0.25 cuft of sandy mud with 

 many animals. In addition to those named in the chart, there was a 

 ceriantharian (1), small anemones (2), a hydroid branch (2), a nemer- 

 tean (2), a branching bryozoan, Glottidia albida (13), amphipods (20), 

 a gnathid isopod (1), a cumacean (3), a small crab (1), a pinnotherid 

 crab (1), a pycnogonid (2), and a sand-covered ascidian (2). Most con- 

 spicuous and abundant species were Glottidia albida (13), tubes of 

 Strehlosoma crassibranchia (many) and Sthenelanclla uniformis (10"^). 



Numbers of species and specimens totalled : 

 polychaetes 41 species, 146 specimens 



echinoderms 6 19 



mollusks 10 32 



crustaceans 5^ 26 



others 7 24 



Total: 69^ species, 247 specimens 



2. Sta. 2176, in 28 fms. OPG took 1.32 cuft of nodular muddy sand 

 and mud. Branching bryozoans and simple ascidians resembling small 

 cindery balls, characterized the screenings. In addition to the species 

 named in the chart, there were an anemone (7), a nemertean (2^), a 

 sipunculid (1), Glottidia albida (4), an ascidian (3), and small crusta- 

 ceans, especially amphipods. 



Numbers of species and specimens totalled : 

 polychaetes 54 species, 300+ specimens 



echinoderms 1 2 "^ 



mollusks 4+ 8+ 



crustaceans 10+ many 



others 6 12+ 



Total: 75+ species, 322+ specimens 



Sta. 2175, in 58 fms. OPG took a small sample of mud and shell 

 fragments, with many diversified animals. The polychaetes which were 

 best represented included some not recovered in other samples, such as 

 A phrodita refulgida, Magelona with serrated prostomial margin, uniden- 

 tified cirratulids, maldanid with parasitic copepod, ampharetids of sev- 

 eral kinds, Megaloinma sp., and spirorbids. 1 he fauna may have affinities 

 with that of the outer shelf. 



Sta. 2174, in 161 fms. OPG took 0.95 cuft of mud with shell frag- 

 ments. The largest animal was a large seastar, Hippasteria sp., accom-
