VI-4, Sta, 2794-54. In 2672 feet. OPG took 3,4 cuft of blue gray 

 mud. The screenings consisted of foraminif eran tests, some siliceous 

 sponge and fragments of tubes ( Phyllochaetopterus and protulid). 



VI-5, Sta, 2729-54, In 2721 feet, OPG took 3.4 cuft of fine 

 green sticky mud. The screenings consisted of about a pint of 

 foraminif eran shells, some siliceous sponge spicules and a few metazoan 

 animals, 



A calanold copepod 



A small gastropod, perhaps Mitrella 

 A small sipunculid

 tests, empty tubes of Phyllochaetopterus , protulid tubes, broken valves 

 of Cyclopecten , and a single large ampharetid, Amage , nr, anops , in 

 a thick mud tube.

 cuft of fine mud. The sediments had no living metazoan animals. 



VI-8, Sta. 2970-54. In 2856 feet. The Campbell grab took 3,59 

 cuft of gray green mud. There were no living metazoan animals, 



VI-9, Sta. 2971-54, In 2910 feet. The Campbell grab took only 

 plankton with ctenophores| It failed to take a bottom sample, 



VI-10, Sta. 3411-55, In 2922 feet, OPG came up with a full 

 (not measured) sample of fine mud. The screenings consisted of many
