30 DISCOVERY REPORTS 



other Foraminifera were not numerous, (ii) A quantity of muddy sand without coarse debris. Many 

 Foraminifera obtained by elutriation and a long Hst of species. Reophax and Haplophragmoides of 

 several species, Recurvoides contortus, Proteonina dijfiugiformis , Pelosina variabilis and Trochammina 

 bradyi were all very common. Among rarer forms were Dendronina arboresceiis var. anfarciica, 

 Astrorhiza triangularis, Pelosina arborescens, Thurammina spumosa and T. corrugata.

14. iii. 27. Schollaert Channel, Palmer Archipelago, 64° 21' S, 62° 58' W. Nets on trawl, 

 278-500 m. 



A small jar of coarse sand and flocculent organic debris. No mud or fine material. Residue 

 coarse angular sand with abundant Reophax pilulifer and other large species of Foraminifera. Among 

 the rarer species were Armorella sphaerica, Thurammina spumosa, Astrorhiza triangularis and Soro- 

 sphaera depressa. Very few of the smaller species were listed.

16. iii. 27. De Gerlache Strait, Palmer Archipelago. Sounding, 598 m. 



About 8 cc. tenacious grey mud gave less than i cc. residue of sand grains of all sizes, diatoms, 

 sponge spicules and eight species of Foraminifera, all represented by single specimens, except 

 Miliammina oblonga, which was evidently dominant in the deposit. 



186. TS 712*, 713. Fig. II, E III. 



16. iii. 27. Fournier Bay, Anvers Island, Palmer Archipelago. Dredge, 295 m. 



About 30 cc. coarse muddy sand with a residue of angular sand grains of all sizes, a few diatoms 

 and Foraminifera. Reophax dentaliniformis was very common; Miliammina oblonga and M. lata 

 common; about thirty other common species varying from frequent to very rare. Nothing very 

 notable except Armorella sphaerica and Ehrenbergina parva. 



187. TS 717, 718*. Fig. II, E III. 



18. iii. 27. Neumayr Channel, Palmer Archipelago, Sounding, 200 m., 259 m. 



Two samples were received. 



(i) About 10 cc. brown mud from 200 m. yielding i cc. residue of angular sand grains of all 

 sizes and large diatoms {Triceratium). Foraminifera inconspicuous, mostly dead shells. Miliammina 

 of various species, Virgulina bradyi and V. schreibersiana were the only forms occurring with any 

 frequency. 



(ii) About 5 cc. dark grey mud from 259 m., with a residue of angular sand grains and diatoms 

 yielded seven species of common Foraminifera, represented in all cases but one by a single specimen.

24. iii. 27. Bismarck Strait, Palmer Archipelago. Large rectangular net, 93-130 m. 



A small quantity of sponge and polyzoan debris with many diatoms. No Foraminifera in the 

 coarse material ; a long list of species was obtained from the finer grades, but with few exceptions 

 specimens of each were not numerous. The common species were Saccorhiza ramosa, Tolypammina 

 vagans, Haplophragmoides canariensis, Trochammina nana, T. ochracea, Discorbis vilardeboanus, 

 Cibicides lobatulus and C. refulgeiis. Among rarer forms of interest were Armorella sphaerica, 

 Turritellella shoneana, Hippocrepitia flexibilis and Spirillina tuberculata. 



191. TS715*. Fig. II, E III. 



25. iii. 27. De Gerlache Strait, Palmer Archipelago. Sounding, 310 m. 



About 15 cc. grey mud, with a residue of sand grains, diatoms, sponge spicules and very rarely 

 Foraminifera. No species except Trochammina inconspicua occurred with any frequency. A single 

 specimen of Lagena striata and one of Spiroplectammina biformis were the only outstanding records.
