MATERIAL EXAMINED 29 



172. No Station slide. Not marked on map. 



26. ii. 27. Off Deception Island, South Shetlands, 62° 59' S, 60° 28' W. Dredge, 525 m. 

 About a pint of coarse scoriae. No organisms found except Tholosina vesicularis.

2. iii. 27. Bransfield Strait, South Shetlands, 63° 17' 20" S, 59° 48' 15" W. (a) Sounding; 

 (b) dredge, 200 m. 



The sounding (a) consisted of a small quantity of muddy sand which gave 2 cc. residue of dark 

 angular sand grains of varying sizes. Few organisms except scanty and pauperate Foraminifera of 

 the usual local species, TurriieUella laevigata being the only one of particular interest. From the 

 dredge was received (i) a tube with picked out specimens oi Pilulinajejfreysii, Planispirina bucculenta 

 and some large Pyrgo ; (ii) a box of stones with a few sessile Foraminifera of the common species ; 

 (iii) a quantity of very dark sand with few apparent organisms. The coarser siftings yielded very 

 few Foraminifera except Reophax spp. and Pyrgo spp. The finer material was floated with carbon 

 tetrachloride and the floatings yielded a very long list of species. The customary fauna was well re- 

 presented, and by numerous specimens. There were also a great number of unusual species including 

 Patellma corrugata, Hormosina ovicula, Thurammina spiimosa, T. albicans, T. corriigata, T. papillata, 

 T. compressa, T. haeusleri, Hyperammina clavigera, Psammophax consociata, Ammodiscoides tur- 

 binatus, Technitella bradyi and many species of Lagena.

5. iii. 27. 27 miles south-west of Deception Island, South Shetlands. Dredge, 1080 m. 



The material received included (i) a tube with some specimens selected from the dredge — • 

 Crithionina pisum, Pelosifia fusiformis, Jaculella obtusa, Rhabdammina discreta and Reophax nodulosus; 

 (ii) a box of stones of all sizes, many of which had sessile Foraminifera including Webbinella depressa, 

 Dendronina papillata and Sorosphaera depressa ; (iii) a quantity of coarse black volcanic sand with few 

 organic remains except a few Arenacea ; and (iv) about 70 cc. of fine black sand, chiefly scoriae. 



Nos. (iii) and (iv) after washing to remove mud were floated with carbon tetrachloride which was 

 only a partial success, as a good deal of pumice floated with the Foraminifera. About 2 cc. of 

 floatings were obtained, so it is clear that Foraminifera formed an infinitesimal proportion of the bulk, 

 certainly less than o-oi per cent. A very large number of species were picked out from the floatings, 

 but with the exception of about twenty of the commoner forms, rarely more than two or three speci- 

 mens of each species. Among the rarer forms listed were Astrorhiza polygona, Ophthalmidium 

 margaritiferum, Trochammina globulosa, several species of Thurammina, Hyperammina clavigera, 

 Bathysiphon argillaceus, Proteonina tubulata, Ehrenbergina pupa, Elphidiiim incertum and Hippo- 

 crepinella alba.

1 1 . iii. 27. 17 miles west of north point of Gand Island, SchoUaert Channel, Palmer Archipelago. 

 {a) Sounding, {b) dredge, 160 m. 



The sounding {a) contained about 14 cc. of brown mud with a residue of angular sand grains, 

 diatoms, sponge spicules and scanty Foraminifera of the usual local species, none of particular in- 

 terest. From the dredge was received a jar of coarse dark sand and mud. Foraminifera formed a 

 very small percentage of the material, and were mainly Arenacea, some of which were very abundant, 

 notably Proteonina diffliigiformis, Psammosphaera fusca, Pelosina variabilis, Reophax scorpiurus, 

 R. pilulifer, R. dentalitiiformis. Other very common species were Globigerina pachyderma, Virgulina 

 bradyi and Miliolina seminulum. A long list of rarer forms.

12. iii. 27. SchoUaert Channel, Palmer Archipelago, 64° 20' S, 63°oi'W. Nets on trawl, 

 160-335 m. 



Two samples received, (i) Muddy sand with about 50 per cent organic debris, principally 

 echinoderm. Pelosina, generally fragmentary, formed a considerable proportion of the coarse residue,
