WS 499. No Station slide. Not marked on map. 



3. i. 30. 65° 45' S, 67° 18' W. Sounding, 179 m. 



A pinch of daA grey sand yielded a worm tube with a specimen of Pullmia subcarinata imbedded, 

 and Crithionina mamilla attached to the tube.

30.1.30. 69° 43' S, 99° 38' W. Sounding, 4224 m. 



A small quantity of very tenacious brown mud was washed twice and left a residue of fine sand, 

 mud pellets and many Arenacea. Except for four specimens representing three species of Globigerina, 

 none but arenaceous species were seen. Haplophraginoides subglobosus was the only species occurring 

 in any numbers. Less common were Cyclammina cancellata, C. pusilla, Psanunosphaera fiisca, 

 Haplophragmoides glomeratus. All the other species very rare, sometimes only one or two specimens. 

 They included Hormosina lapidigera, Spiroplectammina subcylindrica, Spirolocammina tenuis and 

 Thurammina papillata.

30. i. 30. 70° 03' 30" S, 100° 39' W. Sounding, 4072 m. 



A small quantity of tenacious brown mud was washed twice and gave a very minute residue of 

 fine sand and Radiolaria, with a few large Foraminifera and many small species, all very pauperate. 

 Haplophragmoides subglobosus, Cyclammina pusilla and Ammomarginulina ensis were common. No 

 Globigerinae were seen. The remaining species were mostly deep-water Arenacea, the only note- 

 worthy forms being Ammobaculites foliaceiis var. recurva and Spiroplectammina subcylindrica.

4. ii. 30. 70° 10' 30" S, 87° 46' W. Sounding, 1500 m. 



A small quantity of tenacious brown mud which was washed twice, and gave a residue of small 

 pebbles with Placopsilina confusa and Tolypammina vagans attached, angular sand grains of all sizes, 

 Globigerinae and a long list of other Foraminifera. Globigerina pachyderma and G. conglomerata 

 formed nearly 90 per cent of the residue, and most of the remaining species were the normal as- 

 sociates of an Antarctic Globigerina ooze. Among the rarer species were Ammobaculites foliaceus var. 

 recurva, Thurammina castanea, Bolivina ciiicta, B. decussata, B. spinescens, Ehrenbergina hystrix var. 

 glabra and Rupertia stabilis. 



WS 506. TS 735. Fig. I, B IV. 



7.11.30. 70° 31' S, 81° 36" W. Sounding, 584 m. 



A small quantity of brown mud with residue of angular sand grains of all sizes, abundant 

 Globigerinae and many other Foraminifera. Globigerina pachyderma and G. conglomerata were 

 dominant ; Miliammina lata and M. arenacea common. A number of interesting rarities, Bathy- 

 siphon argenteus, Reophax micaceus, R. spiculifer, Virgulina schreibersiana var. complanata, Bolivina 

 spinescens, B. cincta and six species of Lagena.

8.11.30. 70° 32' 30" S, 81° 42' W. Sounding, 572 m. 



A small quantity of tenacious mud was washed twice and gave a residue of sand grains of all 

 sizes, many Globigerinae, fragmentary Arenacea, and many other Foraminifera of varied species, 

 mostly represented by few specimens. Many large Arenacea were present in recognizable fragments, 

 but there were few perfect specimens. Miliammina lata, Bulimina aculeata, Globigerina pachydertna 

 and G. conglomerata all common, the last two dominant in the gathering. A long list of other species, 

 but none of outstanding interest. 



WS 507 B. TS 737. Fig. I, B IV. 



8.11.30. 70° 34' S, 81° 55' W. Sounding, 580 m. 



A small quantity of pale brown mud yielding a residue of angular sand grains and Globigerinae, 

 also other Foraminifera of varied species, but many of them represented by single or few specimens.
