V-35o Sta, 2728-54. In 2670 feet. An unscreened and unfixed 

 sample was examined after it was brought into the laboratory. Only 

 P hyllochaetopterus could be identified. It is possible that lack of 

 preservation on shipboard caused destruction of other animal contents, 



V-34o Sta. 3170-55. In 2760 feet. OPG took 2.58 cuft of green 

 mud. The screenings consisted of f oramlnif eran tests, a few dead

SUT.MARY of V-1 to 37. Redondo Canyon supports a unique fauna, 

 characterized by many species which are sparse or absent In other 

 parts of Santa Monica Bay. Most of its bottoms are soft or muddy. 

 In its moderate depths it supports a Thalassema association, which is 

 replaced in its deeper parts by an ampharetld, and finally by a 

 Phyllochaetopterus association. 



VI-lo Sta» 2791=54o In 2567 feet, OPG took 3.08 cuft of fine 

 blue gray mud. All materials passed through the screens but about 

 a pint of foramlniferan tests and empty tubes of Phyllochaetopterus 

 (deep-water species). ' 



VI-2. Sta. 2620-54. In 2562 feet. OPG took 2.2 cuft of fine

 foramlniferan tests and empty tubes of Phyllochae topterus (deep- 

 water species), 



VI-=3o Sta. 3019-=55. In 2570 feet. The Campbell grab took 5.31 

 cuft of black rock fragments, some of which had dead tubes of fully 

 attached serpulid; there were many siliceous sponge spicules and 

 foramlniferan tests, in addition to animals listed.
