CORAL MUD : Consisting of bottom-living Foraminifera, Coral fi-agments, calcareous Algse, 

 Gasteropods, Pteropods, Echinoid spines, Alcyonarian spicules, Tunicate spicules, and Sponge

No. 18. Jtme 19, 1905. 

 Lat. 5° 41' 20" S., Long. 71° 59' 10" E., 6 miles north of Chagos ; depth, 223 fathoms. 



PTEROPOD OOZE : Dirty white, incoherent, and may not represent the deposit in situ ; it consists 

 of pelagic and bottom-living Foraminifera, Pteropods, Heteropods, Echinoid shell-fragments 

 and spines, Fish otoliths, Tunicate spicules, and a few Coccoliths ; Sponge fragments and 

 'Spicules, Kadiolaria, fragments of arenaceous Foraminifera, and Diatoms; a trace of minute 

 mineral particles ; and a small quantity of fine amorphous clayey matter. 



No. 19. June 20, 1905. 

 Position — 1| miles S.E. of Peros ; depth, 363 fathoms. 



PTEROPOD OOZE : From this station there is very little material, indicating that the deposit is 

 probably Pteropod Ooze, since it contains many fragments of Pteropods and Heteropods, 

 with pelagic and bottom-living Foraminifera, Alcyonarian spicules, Echinoid spines, small 

 Mollusc shells, Tunicate spicules, and Coccoliths ; a few Sponge spicules, lladiolaria, and 

 Diatoms. 



No. 20. June 23, 1905. 

 Lat. 5° 10' 0" S., Long. 72° 15' 30" E., near Salomon; depth, 575 fathoms. 



PTEROPOD OOZE : The material is incoherent, and may not represent the deposit as it is on the 

 bottom; it contains Pteropods, Heteropods, pelagic and bottom-living Foraminifera, fragments 

 of Corals and calcareous Algae, Gasteropods, Lamellibranchs, Echinoid shell-fragments and 

 spines. Fish otoliths, Alcyonarian spicules. Tunicate spicules, and Coccoliths ; Sponge spicules, 

 Radiolaria, and one or two imperfect casts.
