 166° 8' W., 1,894 fms.] 



Material. — 13 c.c. pale broAvn ooze sounding, in formalin, dried yellowish 

 cream. Tenacious and difficult to clean. Sieves contained Globigerina and other 

 Foraminifera, Eadiolaria (chiefly Sphaerellaria) a few angular minerals. Notable 

 species : — SeabrooHa earlandi, Polymorphina lanceolatn, many Lagena including 

 L. danica, L. foveolata, L. longispina, L. seniimda. Residues, amorphous impal- 

 pable mud, with immature Foraminifera, Eadiolaria, diatoms, much calcareous debris. 



No. 18.— Station 171. [Label :— Dec. 10, 1910, 66° 38' S., 178° 47' W., 

 1,964 fms.] 



Material. — 12 c.c. brown mud sounding, in spirit, dried light gre}^ Sieves : — 

 Globigerina and other Foraminifera and debris of the same with Eadiolaria, 

 diatoms and a few angular minerals. Notable species : — Sigmoilina ovata, Anwio- 

 discus cJiaroides, Ehrenbergina hystrix, many species of Lagena, Pidvinulina 

 fauperata. Residues almost entirely organic, Globigerina and diatom debris, 

 Eadiolaria, very fine minerals. 



No. 19.— Near Stations 173-174. Soundmg A. [Label:— Dec. 11, 1910, 

 66° 55' S., 178° 51' W., 2,015 fms.] 



Material. — About 6 c.c. light brown ooze sounding, in spirit, dried very pale 

 brown, broke down readily. An ooze of mixed Globigerina, diatom and mineral 

 origin. Sieves contained thick-walled dead Globigerina, many other Foraminifera, 

 a few mineral grains, some being large, many small pellets of clay which had 

 resisted disintegration. Notable species : — Biloculina elongata, Miliolina tricarinata, 

 Cyclammina pusilla, Sphaeroidin^i bidloides. Residues contained fragmentary and 

 immature Globigerina, diatoms, fine minerals, amorphous pellets of clay. 



No. 20.— Near Stations 173-174. Sounding B. [Label :— Dec. 13, 1910, 

 67° 30' 1" 8., 177° 57' 1" ^\., 2,131 fms.] 



Material. — 15 c.c. brown ooze, in spirit, dried pale grey, and did not readily 

 disintegrate. Dried agaui and broke do-mi in weak soda into a fine homo- 

 geneous mud of mmeral and diatom origin. *S«€ves contained Globigerina and other 

 Foraminifera, angular minerals. Notable species : — Ammodiscus cJiaroides, various 

 Lagena. Residues, angular minerals, inmiature and broken Foraminifera, diatoms, 

 Eadiolaria, sponge-spicules. 



No. 21.— Near Station 227. [Label :— March 14, 1912, 68° 45' S., 172° 38' E., 

 1,749 fms.] 



Material. — A sounding, 12 c.c. pale brown clay in formalin, dried grey, 

 tenacious and difficult to wash even after drying. Sieves contained many mineral 

 grains of varying sizes, abundant sponge-spicules and diatoms, a few Eadiolaria, 

 and very few Foraminifera. Notable species : — Thurammina papillata, var. albicans,
