Station 160, 2nd November, 1899. 

 Lat. 20° 40' S. ; long. 143° 9' W. ; depth, 1609 fathoms. 



GLOBIGERINA OOZE: very little material, incoherent; consisting of 

 Coral fragments, pelagic and bottom-living Foraminifera, Alcyonarian spic- 

 ules, Pteropods and other Molluscs, Echinoid spines; Sponge spicules; and 

 many manganese grains (one or two 2 mm. in diameter). 



Station 161, 2nd November, 1899. 

 Lat. 20° 37' S. ; long. 143° 15' W. ; depth, 574 fathoms. 



PTEROPOD OOZE (?): the material is incoherent, consisting principally 

 of Pteropods, Heteropods, and their fragments, with Coral fragments, 

 pelagic and bottom-living Foraminifera, otoliths, Alcyonarian spicules, Mol- 

 lusc fragments, Tunicate spicules, coccoliths, and rhabdoliths. 



Station 162, 2nd November, 1899. 

 Lat. 20° 37' S. ; long. 143° 18' W. ; depth, 659 fathoms. 



PTEROPOD OOZE or CORAL SAND: very little material, incoherent, con- 

 sisting of Coral fragments, Pteropods, Heteropods, pelagic and bottom- 

 living Foraminifera, Molluscs, Echinoid spines, coccoliths, rhabdoliths, etc. 



Station 163, 2nd November, 1899. 

 Lat. 20° 34' S. ; long. 143° 23' W. ; depth, 1890 fathoms. 



GLOBIGERINA OOZE : the material is incoherent and very fine-grained, 

 consisting principally of minute pelagic Foraminifera, along with a small 

 proportion of larger specimens, bottom-living Foraminifera, Echinoid spines, 

 coccoliths, and rhabdoliths. 



Station 164, 2nd November, 1899. 

 Lat. 20° 29' S. ; long. 143° 29' W. ; depth, 438 fathoms. 



CORAL SAND : very little material, consisting of Coral fragments, Polyzoa, 

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

 one or two pelagic Foraminifera, Alcyonarian spicules, Tunicate spicules, 

 coccoliths, rhabdoliths, etc. Polytrema rubra is very abundant, giving a pink 

 tinge to the otherwise white material.
