THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 135 
Station 171, 3rd November, 1899. 
Lat. 19° 50’S.; long. 145° 3’ W.; depth, 1688 fathoms. 
GLOBIGERINA OOZE: little material, principally pelagic Foraminifera, 
large proportion of small size, bottom-living Foraminifera, Echinoid spines, 
otoliths, coccoliths, rhabdoliths, etc., with many Coral fragments, the largest 
12 mm. in diameter, some of them colored brown on the outside. This de- 
posit is remarkable for the large amount of fine calcareous matter (coccoliths, 
rhabdoliths, primordial cells of Foraminifera, and very small pelagic Foram- 
inifera) associated with such large fragments from the reefs. 
Station 175, 5th November, 1899. 
Lat. 18° 3’S.; long. 147° 48’ W.; depth, 2129 fathoms. 
VOLCANIC MUD (?): little material, apparently washed, consisting almost 
entirely of splinters of recent volcanic glass, with a few pelagic and bottom- 
living Foraminifera, coccoliths, and rhabdoliths. 
Station 176, 5th November, 1899. 
Lat. 17° 54’S.; long. 148° 0’ W.; depth, 832 fathoms. 
CORAL SAND or VOLCANIC MUD: little material, apparently washed, 
consisting of calcareous fragments and volcanic mineral particles in about 
equal proportions; the following were observed: pelagic and _ bottom- 
living Foraminifera, Pteropods and other Molluscs and their fragments, Alcy- 
onarian spicules, Corals, Serpuda, Echinoid spines ; volcanic glass, palagonite, 
felspar, magnetite, etc. 
Station 177, 5th November, 1899. 
Lat. 17° 51’S. ; long. 148° 3’ W.; depth, 142 fathoms. 
A few fragments of vesicular volcanic rock, the largest 10mm. in diameter, 
with one or two calcareous fragments (Molluscs, Corals, bottom-living 
Foraminifera). 
Station 178, 5th November, 1899. 
Lat. 17° 46’S.; long. 148° 23’ W.; depth, 2111 fathoms. 
VOLCANIC MUD: little material, apparently washed, consisting almost 
entirely of small splinters of recent vesicular volcanic glass, with a few 
pelagic Foraminifera.
