Glohigerina pachyderma and G. conglomerata were dominant. Among the common species were 

 Rhahdammina discreta, Bidtmina aculeata and Uvigerina angulosa. Rarer forms included Reophax 

 micaceus, R. spiadifer, Thiirammina spumosa, Verneuilina bradyi var. nite7u, Textularia catenata and 

 several species of Lagena.

ii.ii. 30. 67° 18' S, 69° 28' W. Sounding, 445 m. 



A small quantity of tenacious dark grey mud, with a residue of fine angular sand, diatoms and 

 a few Foraminifera of the common local species. Mdiamnnna arenacea, M. lata and Reophax scorpiurus 

 only were common. No very noteworthy species except Reophax micaceus and Thurammina papillata. 



WS510. TS723. Fig. II, B VI. 



ii.ii. 30. 67° 11' S, 69° 46' W. Sounding, 505 m. 



A small quantity of greenish-grey mud. Residue sand grains of all sizes, diatoms {Coscinodiscus) 

 and a few Foraminifera, Miliammina spp. and Virgidina bradyi being common. Saccorhiza ramosa, 

 Reophax siibfusiformis, Haplophragmoides tndlissatus, Hormosina ovicida and Trochammina bradyi 

 were frequent, other species very rare. They included some interesting forms, Reophax micaceus, 

 R. spiadifer and Hippocrepina oviformis.

Ii.ii. 30. 67° 04' S, 70° 04' W. Sounding, 635 m. 



A small quantity of greenish-grey mud gave hardly any residue but some diatoms [Coscinodiscus 

 sp.) and a few Foraminifera of the usual local species. Globigerina pachyderma and Virgulina bradyi 

 were very common; Bulimina aculeata and B. patagonica frequent; everything else very rare. 

 Among the noteworthy forms were Virgulina schreibersiana var. complanata and Reophax spiculifer. 



WS 512. TS 729*. Fig. II, A V. 



Ii.ii. 30. 66° 57' S, 70° 22' W. Sounding, 652 m. 



A small quantity of grey mud with a residue of diatoms and many Foraminifera. Miliammina 

 (four species), Globigerina pachyderma and Virgulina bradyi were very common; Proieonina dif- 

 flugiformis, Saccorhiza ramosa, Reophax detitaliniformis and Textularia tenuissima frequent ; all other 

 species more or less rare. Proteonina tubulata was the only species of great interest. 



WS513. TS728*. Fig. II, A V. 



II. ii. 30. 66° 49' 30" S, 70° 40' 30" W. Sounding, 560 m. 



A small quantity of tenacious dark grey mud with a residue of sand grains, diatoms, Radiolaria, 

 sponge spicules and a few Foraminifera. Globigerina pachyderma and Miliammina spp. were common, 

 Virgulina bradyi frequent, most other species very rare, and none of special interest. 



WS514, TS727. Fig. II, A V. 



II. ii. 30. 66° 40' 30" S, 71° 01' W. Sounding, 531 m. 



A small quantity of dark grey mud with a residue of angular sand grains, diatoms, Radiolaria 

 and a few Foraminifera. A considerable and varied list of species, none being very common, and 

 many very rare. Among the interesting species were Cystammina argentea and Textularia antarctica. 



WS515. TS726*. Fig. II, A V. 



Ii.ii. 30. 66° 32' 30" S, 71° 20' 30" W. Sounding, 512 m. 



A small quantity of dark grey mud giving a residue of angular sand, Radiolaria, diatoms and 

 scanty Foraminifera. These were varied and chiefly arenaceous, the only species occurring with any 

 frequency being Miliammina oblonga, M. lata, Reophax scorpiurus, Hormosina ovicula var. gracilis and 

 Virgulina bradyi. Globigerina pachyderma was rare; G. bulloides and G. triloba each represented by a 

 single specimen. The other species were nearly all rare or very rare, among them being Reophax 

 spiculifer, Hyperammina ?iovae-zeala?idiae, and fragments of Marsipella cylindrica.
