cata and Alcyonidium enteromorplia (a new species), were restricted 

 to these two stations. There were a few large rocks that were entirely 

 lacking at Station 32. Animals : Hydroids — Lafoeina maxima 

 (AAA). Nematodes — Unidentified species (associated with Alcyo- 

 nidium enter omorpha, hence found only here and at Station 32). 

 Nemerteans — Lineus ruber, i ; Tetrastcmma candidum, 3. Bryo- 

 zoans — Eucratea loricata (A) ; Electra crustulenta (A) ; Termino- 

 flustra memhranaceo-triincata, 1 large col. ; Mucronella microstoma 

 (C) ; Costazia nordenskjoldi (C) ; Alcyonidium enteromorpha (C) 

 (see Station 32) ; Flustrella corniculata (C). Entoprocts — Barentsia

 Pista maculata (AAA). Ophiurans — Amphiura sundevalli, 8; 

 Ophiura robusta, 9; O. sarsi, 18; Ophiopholis aculeata, 5. Amphi-

 arctica, dozens (3-22 mm.). Gastropods — Tachyrhynchus reticulatus, 

 4 ; Aquilonaria turneri, i ; Margaritopsis pribiloffensis, 2 ; Margarites 

 jrigidus, 21. Tunicates — Molgida griffithsi, 4. 



Station 37 was in an area of the rubble zone that was above aver- 

 age in the richness of its fauna. The larger perforated rocks afforded 

 space for attachment for such animals as erect bryozoans and tunicates 

 and the holes in the rocks provided refuge for worms and other ani- 

 mals. Animals: Sponges — Myxilla incrustans, 4. Hydroids — Thui- 

 aria elegans, 10. Anthozoans (octocoral) — Eunephthya rubiformis, 

 several large. Nemerteans — Amphiporus pacificus, 3+ ; Tetrastemma 

 sp., 2 + . Sipunculids — Golfingia margaritacea, 11. Brachiopods — 

 Hemithyris psittacea, 4. Bryozoans — Dendrobeania murrayana (C) ; 

 Stomachetosella distincta, few; Ragionula rosacea, 8 col.; Embal- 

 lotheca stylifera (C) ; Smittina bella (A) ; Costazia ventricosa (C); 

 Myriosouw, subgracile (C) ; Plagioecia grimaldii, few; Diplosolen 

 obeliiim (A) ; Lichenopora verrucaria (A) ; Flustrella corniculata 

 (AA) ; F. gigantea (C). Polychaetes — Arcteobia anticostiensis,
