THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 117 
Foraminifera ; mineral particles (probably about 60 per cent), mean diame- 
ter 0.3 mm., angular and rounded, augite, magnetite, olivine, dark green 
chloritic mineral, labradorite, palagonite, and rock fragments. 
Station 73, 5th October, 1899. 
Lat. 17° 27’S.; long. 149° 32’ W.; depth, 807 fathoms. 
VOLCANIC MUD or SAND: gray, fine-grained, quite incoherent ; appears 
to have been washed ; contains pelagic and bottom-living Foraminifera, Pter- 
opods, Kchinoid spines, Gasteropods (Pleurotoma), Ostracodes, Polyzoa, oto- 
liths, Aleyonarian spicules, Tunicate spicules, coccoliths, rhabdoliths ; angular 
mineral particles, 0.15 mm. mean diameter obsidian, felspar, augite, mag- 
netite ; one or two coprolites observed. 
Station 76, 6th October, 1899. 
Lat. 15° 56.2’ 8. ; long. 147° 40’ W.; depth, 2269 fathoms. 
GLOBIGERINA OOZE: light brown, coherent; very little material, con- 
taining about 50 per cent calcium carbonate, which consists of pelagic and 
bottom-living Foraminifera, mostly fragmentary, small Fish teeth, cocco- 
liths and rhabdoliths ; small mineral particles including obsidian and felspar. 
Station 77, 7th October, 1899. 
Lat. 16° 3’8.; long. 147° 11’ W.; depth, 1322 fathoms. 
GLOBIGERINA OOZE: cream colored, granular, slightly coherent; con- 
taining no amorphous clayey matter, but large numbers of small pelagic 
Foraminifera, bottom-living Foraminifera, Echinoid spines, Coral fragments, 
otoliths, Ostracodes, fragment of Dentalium, Fish teeth, coccoliths, rhabdo- 
liths, one or two Pteropod fragments, Tunicate spicules, and small calca- 
reous bodies (horseshoe shaped); Radiolaria, Sponge spicules, Diatoms; a 
very few small mineral particles, including augite and olivine. 
Station 78, 7th October, 1899. 
Lat. 16° 8’ S.; long. 146° 42’ W.; depth, 609 fathoms. 
PTEROPOD OOZE: cream colored, granular, slightly coherent; very little 
fine material ; seems to have been washed ; contains pelagic and bottom-living 
Foraminifera, Pteropods, Heteropods, Echinoid spines, small Lamellibranchs 
and Gasteropods (small Pleurotoma), otoliths, Ostracodes, Fish teeth, cocco- 
liths, rhabdoliths, and Tunicate spicules; Sponge spicules, Radiolaria, Dia- 
toms; obsidian, felspar, and magnetite.
