132 THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 



Station 153, 1st November, 1899. 

 Lat. 19° 45.5' S. ; long. 139° 54' W. ; depth, 1494 fathoms. 

 GLOBIGERINA OOZE with manganese : very little material, apparently 

 washed, consisting of pelagic Foraminifera, Ostracodes, etc., mixed with 

 many grains and fragments of manganese, the largest attaining a diameter 

 of 3 mm., with black shining fracture. 



Station 154, 1st November, 1899. 

 Lat. 19° 52' S. ; long. 140° 16' W. ; depth, 2284 fathoms. 

 RED CLAY : small quantity of material, yellowish brown in color, clayey ; 

 consisting of pelagic Foraminifera, Echinoid spines, bottom-living Fora- 

 minifera, Fish teeth, coccoliths, rhabdoliths ; residue dark brown, many 

 grains and particles of manganese (one 4 mm. in diameter), phillipsite, 

 felspar, volcanic glass, etc. A very small portion of the sample gave 24.5 

 per cent calcium carbonate, but the material available is quite inadequate 

 for a detailed description. 



Station 155, 1st November, 1899. 

 Lat. 20° 7' S. ; long. 141° 0' W. ; depth, 2391 fathoms. 



Half a dozen small grains of manganese, the largest 2 mm. in diameter. 



Station 158, 2nd November, 1899. 

 Lat. 20° 43' S. ; long. 143° 5' W. ; depth, 649 fathoms. 



CORAL SAND : very little material, apparently washed ; consisting of 

 Coral fragments, Polyzoa, Pteropods, Heteropods, pelagic and bottom-living 

 Foraminifera, otoliths, Alcyonarian spicules, Echinoid fragments and spines, 

 Mollusc-shell fragments. Tunicate spicules ; Sponge spicules. 



Station 159, 2nd November, 1899. 

 Lat. 20° 42' S. ; long. 143° 3' W. ; depth, 736 fathoms. 



CORAL SAND : the material is quite incoherent ; probably washed ; 

 consisting of Coral fragments (the largest 13 mm. in diameter), pelagic 

 and bottom-living Foraminifera, Pteropods, Heteropods, and other Molluscs, 

 Polyzoa, Echinoid spines, otoliths, Alcyonarian spicules, Serpula tubes; 

 Sponge spicules.
