includes worn fragments of large scallop shells ; a damaged simple coral is also present. There is a 

 subordinate proportion of flocculent material. 



Station WS 92. 8. iv. 27. Lat. 51 58' 30" S. Long. 65 01' W. 145 m. (Plate XVIII.) 

 Sand. A clean sand with rounded mineral grains, the majority of which are about 0-2 mm. in 

 diameter, though some reach 0-5 mm. Besides the predominant quartz, which is often stained, there 

 are many opaque grains, some of which may be glauconite. Grains of hypersthene are plentiful and 

 some worn crystals (beautifully pleochroic) reach a length of 0-5 mm. Green hornblende also is seen, 

 though rarely. Occasional Foraminifera are noted. The finer fraction is flocculent when examined in 

 quantity and contains extremely small mineral particles, spicules, Foraminifera and diatoms. 



Station WS93. 9. iv. 27. Lat. 51° 52' 30" S. Long. 6i°3o'W. 7 miles S 8o° W of Beaver 

 Island, West Falkland Island. 133 m. (Plate XVIII.) 



Sand. A clean sand with some muddy material. The sample is rather coarser than that from the 

 preceding station (WS 92), the rounded mineral grains reaching a diameter of 0-5 mm. or more. The 

 sand is chiefly composed of quartz grains but also includes worn crystals of hypersthene, rounded 

 shell fragments, Foraminifera in some abundance, and broken echinoid spines. There is a fair 

 amount of flocculent material containing tetrad sponge spicules and diatoms. 



Station WS 94. 16. iv. 27. Lat. 50 00' 15" S. Long. 64 57' 45" W. no m. (Plate XVIII.) 

 Sand. A clean sand with rounded grains, many coloured ones mingled with the predominant 

 quartz. Grains of hypersthene are plentiful and some crystals (up to 0-5 mm. in length) are only 

 slightly rounded. No shelly matter was seen and there is little flocculent material. 



Station WS 95. 17. iv. 27. Lat. 48 58' 15" S. Long. 64 45' W. 109 m. (Plate XVIII.) 

 Sand. The sand is clean and composed of rounded grains of quartz and coloured minerals, among 

 which hypersthene is prominent, with an average diameter of about o-2 mm. There are many 

 small pebbles, but virtually no shelly matter as sand. A layer of flocculent material has separated out 

 at the top of the sample ; this is of the usual type, but centric diatoms (especially Cosci/iodiscus) are 

 conspicuous in it. 



Station WS 96. 17. iv. 27. Lat. 48 00' 45" S. Long. 64 58' W. 96 m. (Plate XVIII.) 

 Sand. A dark, evenly graded sand, the rounded and often stained quartz grains having an average 

 diameter of about 0-3 mm. Occasional grains of hypersthene are noted. There is no shelly material. 



Station WS 97. 18. iv. 27. Lat. 49 00' 30" S. Long. 6i° 58' W. 146 m. (Plate XVIII.) 

 Sand. A brownish fine-grained sand with a fair proportion of finer material. The mineral grains 

 reach a diameter of 0-5 mm. though most are smaller; they are usually rounded and stained. Besides 

 the preponderant quartz, grains of hypersthene are plentiful. The shelly material includes Fora- 

 minifera, broken molluscan shells and worn echinoid spines. The flocculent material consists of 

 extremely small particles, mostly indeterminate but including some mineral grains and fragments of 

 foraminiferal tests, also sponge spicules and elongate diatoms. 



Station WS 98. 18. iv. 27. Lat. 49 54' 15" S. Long. 6o° 35' 30" W. 173 m. (Plate XVIII.) 

 Sand. A fine non-graded, dark sand with much flocculent matter containing occasional diatoms. 

 Mineral grains reach a diameter of 0-5 mm. and grade downwards to very small dimensions. Glau- 

 conite seems to be present as internal moulds of foraminiferal shells of which one species is fairly 

 abundant. 



Station WS 99. 19. iv. 27. Lat. 49 42' S. Long. 59 14' 30" W. 251m. (Plate XVIII.) 

 Sand. A fine even-graded sand composed mainly of rounded quartz grains, between 0-2 and o-i mm. 

 in diameter; the dark-coloured grains include some glauconite. This green material is also seen in- 

 filling the canals of broken sponge spicules. There are few foraminiferal or other shells. Some amount 

 of flocculent material is present.
