THE DEPTH AND MAllINE DEPOSITS OF THE PACIFIC OCEAN. 135 



Station 171, Srd 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, Serpula, 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 fragmentsof vesicular volcanic rock, the largest lOiiun. 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.
