FOUAMINIFEKA-HERON-ALLEX AND EAKLAND. 57 



No. 49.— Near Station 335. Jan. 20, 1912, 77° 10' 8" S., 1G4° 13' E., 187 fms. 



Material.^ A sounding, 9 c.c. of dark olive sandy nuid, in formalin, dried grey. 

 Sieves contained dark minerals, Polyzoan and Annelid debris, abundant sponge-spicules 

 and diatoms, very few Foraminifera. Notable species :~Reophax dentaliniformis 

 and Operculina ammonoides. Residues consisted of minerals, rounded and angular, 

 abundant diatoms and sponge-spicules, a few Radiolaria. 



No. 50.— Station 338. Jan. 23, 1912, 77° 13' S., 164° 18' E., 207 fms. 



Material. — Corallines encrusted with Truncatulina refulgens, coralline- and sponge- 

 debris, much organic fiocculent matter, mud and fine black rounded volcanic sand, 

 in formalin. Difficult to wash. Sieves contained a felt of debris. Foraminifera 

 fairly numerous, but more or less decalcified by the formalin. Notable species : — 

 Miliolina oblonga, var. arenacea, M. calcarata, Iridia diaphana, ReopJiax dentalini- 

 formis, Tkurammina papillata, var. favosa (compressed type). Residues., dark 

 angular minerals, sponge-spicules, diatoms, a few innnature Arenacea. 



No. 51.— Station 333. Jan. 17, 1912, 77° 22' 5" S., 165° 22' E., 418 fms. 



Material. — A sounding, 12 c.c. dark olive green (almost black) mud, in for- 

 malin, dried white-grey with a green tinge. Sieves contained rounded and angular 

 minerals, some Radiolaria, sponge'«picules and a few Foraminifera in poor con- 

 dition, all Arenacea except Miliolina oblonga, var. arenacea, which itself is of 

 adventitious construction. How far the formalin was responsible for the entire 

 absence of calcareous forms is unknown. Residues almost entirely diatomaceoiis, 

 with some sponge-spicules and minerals. 



No. 52.— Station 342. Jan. 31, 1912, 77° 36' S., 165° 30' E., 416 fms. 



Material. — Soundings, 18 c.c. dark olive nuul with darker grains, in formalin, 

 dried light grey, and proved very refractory. Sieves contained angular minerals, 

 lumps of grey mud resisting disintegration, many sponge-spicules, Radiolaria and 

 diatoms, very few Foraminifera, principally Arenacea. Notable species : — 

 Miliolina oblonga. var. arenacea, Reopha.r dentali)iifor)nis. Bolivina punctata, var. 

 arenacea, Verneuilina ;/:)itsiZfa. Residues, diatoms with angular minerals, sponge- 

 spicules and Radiolaria. 



No. 53.— Station 348. Feb. 13, 1912, off Barne Glacier, McMmxlo Sound. 

 200 fms. 



Material. — Polyzoan and other organic debris and muddy sand, in formalin. 

 Sieves contained debris, sponge-spicules, diatoms, a few minerals, a few Foram- 

 inifera, mostly small. Notable species : — Iridia diaphana, Thurammina papillata. 

 var. haeusleri, Bulimina chapmani, Discorbina cJiasteri. Residues, diatomaceous 

 with some sponge-spicules, a few minerals and minute Foraminifera. 



No. 54. -Station 314. Jan. 23, 1911, 5 miles North of Inaccessible Island, 

 McMurdo Sound, 222-241 fms. [Label: Jan. 23, 1911, McMurdo Sound.]
