WS 516. TS 725. Fig. II, A V. 



12. ii. 30. 66° 25' 30" S, 71° 38' 30" W. Sounding, 261 1 m. 



A small quantity of tenacious though sandy brown mud. It did not clean readily and was washed 

 twice. The residue was mainly a coarse angular sand, with a little fine sand, some Radiolaria and few 

 but very varied Foraminifera, all with arenaceous shells except Globigerina pachyderma, which was 

 frequent, and one specimen of Cibicides refulgens. Most of the species were represented by a single 

 specimen or a few at most. Among the more interesting were Gaudryinaferruginea and Trochammitia 

 globulosa.

12. ii. 30. 66° 17' 30" S, 71° 57' W. Sounding, 2770 m. 



A small quantity of brown mud with a residue of small pebbles, angular sand grains, many 

 Radiolaria and Foraminifera. Quite a long list of species but most of them rare, or even represented 

 by single specimens. Among the rarities were Placopsilinella aurantiaca, Marsipella cylindrica, 

 Thurammina spumosa, T. miirata, Reophax sabulosus, Ehrenbergina hystrix var. glabra, Bathysiphoti 

 argenteus and Reophax communis.

3. ii. 31. 68° 53' S, 13° 03' W to 68° 50' S, 13° 03' W. Sounding, 4845 m. 



42 cc. of grey mud, leaving 1-25 cc. of residue on 200-mesh silk: quartz sand with many 

 Radiolaria and cosmopolitan Arenacea. A single very small specimen of Cassidulina crassa was the 

 only Foraminifer apart from the Arenacea. 



This station is not very far from Scotia Sts. 420 and 421. 



WS 553. TS 627 B*. Fig. I, J III. 



4. ii. 31. 66° 14' S, 15° 34' W. Sounding, 5029 m. 



50 cc. of grey plastic mud leaving less than i cc. on 200-silk gauze. Radiolarian ooze with 

 very few Foraminifera, all arenaceous except Globigerina pachydermia, and generally of cosmopolitan 

 deep-water species. 



WS 555. TS 627 A*. Fig. I, J II. 



6. ii. 31. 60° 27' S, 19° 36' W. Sounding, 3850 m. 



36 cc. of grey mud, less than 5 cc. remaining after washing on 200-mesh silk gauze. Residue 

 almost entirely arenaceous Foraminifera of cosmopolitan species, the only exceptions being single 

 specimens of Globorotalia truncatulinoides and Globigerina inflata ; Clavulina communis was common, 

 Verneuilina bradyi very rare. Many unquestionably fossil Globigerinae were present, only Globigerina 

 pachyderma being identifiable with certainty owing to erosion and infiltration. 



No Station no. TS 716. Fig. II, E III. 



12. xii. 29. Port Lockroy, Wiencke Island, Palmer Archipelago. Anchor mud. 



About 20 cc. of dark slate-coloured mud, yielding a residue of fine angular sand with much 

 mica, some diatoms and a few Foraminifera. Trochanimina malovensis, T. ochracea and T. rotali- 

 formis were all very common ; Verneuilina advena, Textularia nitens, and Spiroplectammina biformis 

 frequent ; other species very rare and none of particular note. 



No Station no. No Station slide. Not on map. 



I. ii. 30. 70° 01' S, 100° 39' W, very near St. WS 503. Obtained from an iceberg. 



About a quarter of a pint of light grey mud gave a residue of small pebbles and angular sand 

 grains of all sizes, without any trace of organic remains — not even diatoms.
