FORAMINIFER A— HERON-ALLEN AND EAULAND. 51 



Ammodiscus charoides, CycUniujuiM pus ilia. Residues, a tine mud of iiiinerals, 

 diatoms, sponge-spicules witli a few Radiolaria. 



No. 22.— Near Station 180. [Label :— Dec. 20, 1910, 68° 40' 5" S., 

 179° 27' 7" W., 1,802 fms.] 



Material. — A sounding 13' 5 c.c. yellowish brown mud, in spirit, dried light 

 grey and broke d(nvn readily. Sieves contained Globigerina and other Foramini- 

 fera with angular minerals of varying sizes in about equal proportions, also 

 many Radiolaria, a few diatoms and sponge-spicules. Notable species : — Marsi- 

 pella cylindrica, Reophax difflugiformis, Haplophrafpnimii sphaeroidiniforme, Bolivina 

 decussata, varied Lagena. Residues, Globigerina debris, minerals, Radiolaria and 

 diatoms, the finest residue largely diatomaceous. 



No. 23.~Station 184. [Label :— Dec. 26, 1910, 69° 08' 8" S., 178° 12' 7" W., 

 1.816 fms.] 



Material. — A sounding, 12 c.c. pale brown mud in spirit, dried very pale" 

 brown, but did not break down in water. Dried again and broke down m weak 

 soda into an impalpable mud of mineral origin. Sieves contained abundant 

 angular mineral grains, some large with sessile organisms, Globigerina and other 

 Foraminifera, clay pellets, some sponge-spicules, and a few diatoms. Notable 

 species : — Spiroloculina tenuis, Cyclammina pusilla, varied Lagena, Nodosaria 

 raphanistrum. Residues, heavy clay-pellets and angular minerals, foraminiferal 

 debris, diatoms. 



No. 24. Near Station 184. [Label :— Dec. 28, 1910, 69° 16' 6" S., 179° 

 43' 2" W., 2,035 fms.] 



Material. — A sounding, 15 c.c. light brown clay, in spirit, dried light grey 

 and did not break down in water. Dried again it broke down into layers. Dried 

 once more it broke down in weak soda into a fine mud of mixed mineral and 

 organic origin, still exhibiting a tendency to cohere into pellets. Sieves contained 

 angular minerals of varying sizes, some large, sponge-spicules, clay-pellets, a few 

 large diatoms and Radiolaria but practically no Foraminifera, the only species 

 recorded being Psammosphaera fusca, Haplophragmiwn latidorsatmn, Cijclammina. 

 pusilla, Globigerina duterirei. Residues, mineral particles cohering into pellets, diatoms. 



No. 25. Near Station 193. [Label :— Feb. 22, 1911, 68° 41' 6" S., 165° 57' 

 E., 1,435 fms.] 



Material. — A sounding, 12 c.c. of tenacious brown clay with dark specks, in 

 spirit. Dried light grey and broke up into a fine mud of mineral and diatom 

 origin with abundant sponge-spicides and some Radiolaria, but very few Foram- 

 inifera. Notable species ■.—Cijclammina pusilla, Reophax difflugiformis, Haplo- 

 phragmium tenuimargo, Hormosina globidifera, Trochammina tndlissata, T. rotakformis. 

 Residues, diatoms and diatomaceous debris, sponge-spicules, Radiolaria, mmerals,
