 I ; Chaetocone setosa, 1 ; and Brada inhabilis, 5. 



It was impossible to pick over minutely the entire mass of worm 

 tubes of Pista brought up; they were hard to untangle, and it was 

 very difficult to remove a worm intact from its tube. A few (about 

 115) — both tubes with worms and worms that had been removed — 

 were sent to Dr. Pettibone. 



Other animals from this station were : Sponges — Craniella sp. nov., 

 2 ; Echinoclathria heringensis, 3. Nematodes — unidentified species

 2+; A. lactifloreus, 3; Cerehrahdus marginatus, i. Sipuncu-

 Brachiopods — Diestothyris spitzhergensis, 5. Bryozoans — Eucratea

Station 33 was in a good area of the rubble zone, for it yielded a 

 large number of species and of individuals. Many of the rocks were 

 perforated with burrows and holes. Those areas in which Psoitis and 

 sea urchins were abundant were always rich in other animal life : 

 Sponges — Leiiconia sp. nov., 6+ ; Echinoclathria beringensis, sev- 

 eral; Myxilla incrusfans, few. Hydroids — Tubttlaria sp., 8; Thuiaria
