 individual was the sea whip, the most abundant species Dorvillca articu- 

 lata (437), Capitella cnpitata subsp. (190*), and Telepsavus costarutn

 animal was Molpadia intermedia, the most abundant species Tharyx 

 spp. (1620"^) and Spiophancs (100*). Crustaceans and echinoderms were 

 nearly absent.

 nemerteans (30), a phoronid (4), a hirudinean (1), an amphipod (2), 

 a caprellid (1), Scalpellum (12), were taken in addition to those listed
