84 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I28 



Station 53 was undoubtedly in the rubble zone but the small 

 bottom sampler brought up nothing but mud. Numerous holes were 

 made through the ice in a search for rubble bottom that was not 

 covered with mud. 



Station 53a was also in the mud-covered rubble zone. A bottom 

 sampler was used and only a few animals were brought up : Amphi- 

 pods — Socarnes hidenticulatus, 1 (juvenile, 6.5 mm.) ; Melita for- 

 mosa, I (c^). 



Station 53b was in the mud-covered rubble zone off Browerville 

 (a portion of Barrow Village). It was 2.5 miles from shore. Bottom 

 samples were taken at intervals in a line from Station 53a to 53b 

 about 2.5 miles from shore, in a futile attempt to find an area not 

 covered by mud. The following animals were taken: Polychaetes — 

 Eteone spetshergensis, i. Amphipods — Melita jormosa, 1 {^). 



Station 54 was in the true mud zone. Animals : Anthozoans — 

 Cerianthus sp., 7. Polychaetes — Nephtys ciliata, 5. Pelecypods — 

 Nucula tenuis, 3; Macoma calcarea, 41. 



Station 55 was in the mud-covered rubble zone. The animals 

 taken, especially the Cerianthus, indicate that they had reestablished 

 themselves after the disturbance the preceding fall : Anthozoans — 

 Cerianthus sp., 30. Pelecypods — Yoldia hyperborea, i ; Macoma 

 calcarea, 34. 



Station 55a was in the mud-covered rubble zone. It yielded few 

 animals, among which were Pelecypods — Yoldia hyperborea, 5; Ser- 

 ripes groenlandicus, 2. 



Station 56 was also in the mud-covered rubble zone. Some of 

 the animals collected there were obviously reestabUshing themselves. 

 Anthozoans — Cerianthus sp., 5. Pelecypods — Nucula tenuis, 3 ; 

 Yoldia scissurata, i ; Y. hyperborea, 2 ; Serripes groenlandicus, 3 ; 

 Macoma calcarea, 20. 



Station 57 was undoubtedly in the mud-covered rubble zone, 

 though at borderline depths of around 118 feet it would have been 

 difficult during the summer of 1950 to determine whether the station 

 was in the mud zone with stones from the rubble zone deposited there 

 or in the rubble zone with a mud deposit. Some of the animals from 

 this station were: Nemerteans — Amphiporus lactifloreus, 8. Bryo- 

 zoans — Vesicularia fasciculata, n. sp., few. Polychaetes — Chone in- 

 fundibuliformis, 5. Amphipods — Haploops laevis, 18 -F. Pelecy- 

 pods — Nucula tenuis, 17; Yoldia my alls. 2; Astarte montagui, 4; 

 Macoma calcarea, 14. 



Station 58 was also undoubtedly in the mud-covered rubble zone. 

 Some of the animals, such as Nucula tenuis, were obviously trans-
