Material— A soundiug. 12 c.c. of yellow-grey diatom ooze, with many dark 

 mineral grains, in formalin, dried light grey. Sieves contained dark rounded 

 minerals, sponge-spicules and Foraminifera. Notable species ■.—Bathjsiphon 

 argenfeus, Haplojihragmhm fontinense, H. gloiuemtum, Trochainmitia tndUssata._ 

 Residues consisted of diatoms and sponge-spicules. 



No. 45.— Station 340. Jan. 25, 1912, 76° 56' S., 164" 12' E., 160 ims. 



Material. — Debris of Polyzoa, Echinoderms and Sponges with a small quantity 

 of muddy sand, in spnit. Difficult to clean. Sieves contained a felt of debris 

 with rounded minerals, diatoms, sponge-spicules and Foraminifera. Notable 

 species : — Dendronina arborescens, var. antarctica, Rhizammina algaefonnis, Criihionina 

 pisum, Reovhax advena, Thurammina pajnlhta. var. haeusleri. Residues consisted of 

 minerals, abundant diatoms and sponge-spicules, and many immatm-e Foraminifera. 



No. 46. — Station 356. Jan. 22. 1913, off Granite Harbour, entrance to 

 McMurdo Sovmd, 50 fms. 



Material. — Organic debris with a little sand, in spnit, difficidt to clean. 

 Sieves contained a felted mass of sponge-fragments and spicules, with scanty 

 Foraminifera. Notable species : — HapJophragmium nanuw. H. caiiariense, var. 

 variabilis, Thurammina papillata. var. haeusleri, Bulimina chapmani, Cassididina 

 parl-eriana, Ehrenbergina hystrix, var. glabra. A small Pycnogonid was observed 

 bearing sessile specimens of Ammodiscus gordialis (many) Trochammina squamata, 

 Disrorhina globularis and TruncatuUrm refulgens. Residues consisted of diatoms, sponge- 

 spicules and minerals. 



No. 47.— Station 339. Jan. 24, 1912, 77° 5' S., 164° 17' E.. 140 fms. 



Material. — Polyzoan and Echinoderm debris with a little black sand, 

 in formalin. Difficult to clean. Sieves contained a felt of debris, biit very few Fora- 

 minifera except Truncatulina refulgens, which was abimdant. Notable species : — 

 Reojjhax longi.scatifor)nis. Thurammina papillata. var. haeusleri and Patellina corrugata, 

 showing development of young individuals in basal cavity. Residues consisted of 

 dark angular minerals, a few sponge-spiciUes and diatoms, and very few immatiire 

 Foraminifera. 



No. 48.— Station 331. Jan. 14, 1912. Off Cape Bird Penmsula, entrance to 

 McMiu-do Sound, 250 fms. 



Material. — Sand and organic debris in spirit, similar material in formalin, and a few 

 selected Foraminifera. Sieves contained a mass of Echinoderm, Polyzoan, Hydrozoan 

 and sponge debris, with black volcanic sand. Foraminifera poorly represented except 

 Cassidulina, very common. Notable species : — Miliolina calearata, Iridia diaphana, 

 Pelosina cylindrica, Ammodiscus shoneanus. A specimen of Truncattdina lobatula con- 

 taining embryo shells was recorded. Residues consisted of angular minerals, volcanic 

 ash, sponge-spicules in great abundance, diatoms, and a few immature Foraminifera.
