134 THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 
Station 165, 2nd November, 1899. 
Lat. 20° 27’ S.; long. 143° 32’ W.; depth, 406 fathoms. 
CORAL SAND: very little material, consisting of Coral fragments, Ptero- 
pods and Heteropods and other Molluscs, pelagic and bottom-living Forami- 
nifera, Aleyonarian spicules, Kchinoid spines, Tunicate spicules, coccoliths, 
and rhabdoliths. 
Station 166, 2nd November, 1899. 
Lat. 20° 15’ S.; long. 144° 0’ W.; depth, 2265 fathoms. 
GLOBIGERINA OOZE or RED CLAY: little material, which does not ap- 
parently represent the deposit i situ; containing pelagic and bottom-living 
Foraminifera, crystalline calcareous particles (dolomitic limestone), coccoliths, 
rhabdoliths, and other calcareous bodies (horse-shoe shaped); with many 
manganese grains and nodules, the largest 10 mm. in diameter, consisting 
of volcanic glass in various stages of decomposition impregnated and coated 
with manganese. Some of the volcanic glass fragments are entirely con- 
verted into palagonite of a brilliant red color, others greenish, and one 
nodule quite white internally was composed of unaltered volcanic glass with 
a thin covering of manganese ; some are free from manganese, and others 
only slightly blackened; phillipsite in twins and isolated crystals was also 
observed. 
Station 168, 3rd November, 1899. 
Lat. 19° 54’ S.; long. 144° 48’ W.; depth, 1719 fathoms. 
GLOBIGERINA OOZE: very little material, apparently washed ; consisting 
almost entirely of pelagic Foraminifera, a large proportion of small size, 
with one or two bottom-living forms, coccoliths, and rhabdoliths. 
Station 169, 3rd November, 1899. 
Lat. 19° 54’S.; long. 144° 53’ W.; depth, 594 fathoms. 
CORAL SAND: very little material, apparently washed, consisting of Coral 
fragments, Pteropods and Heteropods and other Molluscs, pelagic and 
bottom-living Foraminifera, Echinoid spines, Polyzoa, Serpula, ete. 
Station 170, 3rd November, 1899. 
Lat. 19° 54’S.; long. 144° 59’ W.; depth, 189 fathoms. 
CORAL SAND : very little material, apparently washed, consisting of Coral 
fragments, Pteropods and other Molluscs, pelagic and bottom-living Forami- 
nifera, etc.; several particles of iron rust, evidently from sounding machine.
