33 DISCOVERY REPORTS 



a considerable number of species of Foraminifera, mostly represented by one or two specimens. The 

 only species occurring with any frequency were Miliammina arenacea, M. oblonga, Trochammina 

 ochracea and Uvigerina angulosa. Ten species of Lagena were recorded.

5. iv. 27. Bransfield Strait, South Shetlands, 63° 30" S, 59° 06' 30" W. Sounding, 343 m. 



The tube broke and most of the sounding was lost. About 4 cc. dark mud which was left yielded 

 a residue of dark sand, many diatoms and Foraminifera. With the exception of Cassidiilina crassa, 

 which was common, and Globigerina (three species) frequent, the remaining species were represented 

 by a few specimens only, none being of outstanding interest.

5. iv. 27. Bransfield Strait, South Shetlands, 62° 48' S, 60° 05' W. Sounding, 909 m. 



About 15 cc. dark brown mud left a residue of 3 cc. black volcanic sand with few organic re- 

 mains. There were a fair number of species of Foraminifera, but with the exception of Miliammina 

 arenacea and Bolivina punctata, not more than single or few specimens of each, and nothing of out- 

 standing importance.

5. iv. 27. Bransfield Strait, South Shetlands, 62° 56' S, 59° 50' W. Sounding, 949 m. 

 About 15 cc. tenacious dark brown mud which left a residue of 2 cc. black volcanic sand. 



Foraminifera few in numbers and pauperate, but varied in species. Psammosphaera fusca, Reophax 

 scorpiurus, Recurvoides contortus, Miliammina arenacea, M. obliqua, Bolivina punctata, Virgulina 

 bradyi, Globigerina pachyderma, Nonion depressulus and Nonionella iridea were the only species re- 

 presented in any numbers. Ehrenbergina parva was the only noteworthy rarity.

6. iv. 27. Bransfield Strait, South Shetlands, 63° 05' S, 59° 42' W. Sounding, 943 m. 

 About 12 cc. dark brown mud gave a residue of black volcanic sand with few organisms of any 



kind. Foraminifera very rare except Miliammina oblonga, Trochammina malovensis, T. nana, 

 Virgulina bradyi and Textularia tenuissitna. Nothing outstanding among the other species recorded.

6. iv. 27. Bransfield Strait, South Shetlands, 63° 26' S, 59° 28' W. Sounding, 310 m. 



About 15 cc. dark brown mud left 3 cc. residue of grey sand with many diatoms and few 

 Foraminifera. Miliammina arenacea, Trochammina ochracea and T. roialiformis were the only species 

 occurring with any frequency. Among the rarer forms were Thurammina haeusleri and a fragment of 

 Psammatodendron indivisum.

14. iv. 27. Port Foster, Deception Island, South Shetlands. Sounding, 168 m. 



About 25 cc. brown mud yielded as residue a large water-worn lump of pumice, some mud 

 lumps and many Foraminifera of few species. Miliatnmina oblonga, M. obliqua and Trochammina 

 malovensis were common, Reophax dcfitaliniformis and R. fusiformis frequent. Among rarer species 

 were Textularia nitcns, Spiroplcctammina biformis and Ehrenbergina parva.

24. ii. 30. 55° 53' S, 32° 33' W to 55° 50' S, 32° 26' 30" W. Sounding, 3264 m. 



A small quantity of ooze, diatoms, Radiolaria and fine rounded sand grains in about equal pro- 

 portions. Foraminifera very rare, all small species or pauperate forms of larger species, but fur- 

 nishing a varied list. None of the species was other than rare and many were represented by one or 

 two specimens. Among them were several interesting forms, Gaiidryina ferruginea, Nodellimi 

 membranaceum, Reophax communis, Spirolocammina tenuis, Trochammina vesicularis, Spiroplcct- 

 ammina subcylindrica, S. typica, S. filiformis, Spiropleciella cylindroides and Gaiidryina minuta.
