THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 129 



(9) Oblong flat piece of yellowish colored clay, 22 by 11 by 7 mm., 

 compact, fine-grained, can be scratched with the finger-nail, spotted on 

 all sides witli imperfect dendrites of manganese, edges angular, somewhat 

 brick shaped with a slight bend, not unlike a piece of decomposed earth- 

 enware ; contains in its argillaceous ground-mass fibrous glassy particles 

 and undeterminable crystalline particles. 



Station 134, 28th October, 1899. 

 Lat. 18° 6' S. ; long. 142° 24' W. ; depth, 807 fathoms. 



CORAL SAND or PTEROPOD OOZE: cream colored, with blackened 

 Coral fragments, granular, incoherent ; appears to have been washed ; con- 

 sists of Coral fragments, Pteropods, Heteropods, pelagic and bottom-living 

 Foraminifera, otoliths, Ostracodes, Echinoid spines. Mollusc-shell fragments, 

 small Lamellibranchs and Gasteropods, Tunicate spicules, rhabdoliths, eocco- 

 liths ; Sponge spicules, Radiolaria ; obsidian, plagioclase, and other felspars, 

 manganese grains. 



From this station were also obtained some Coral fragments blackened 

 with manganese, small cinders, fragments of calcareous matter coated with 

 manganese, similar to specimens (4) to (6) at Station 133, and a piece of 

 what appears to be consolidated ooze, about | inch in diameter, made up 

 of pelagic Foraminifera, etc. ; also a piece of anthracite, flat, almost rectan- 

 gular, 12 by 9 by 2 mm., similar to specimen (2) at Station 133. 



Station 135, 28th October, 1899. 



Pass between Marokau and Ravahere, Paumotu Islands ; 



depth, 278 fathoms. 



Very little material, from which it is impossible to state the type of 

 deposit in situ, consisting of grains of Coral coated with manganese, the 

 largest being 6 by 1 mm.; one or two pelagic Foraminifera {Globigerina). 



Station 137, 29th October, 1899. 

 Lat. 18° 7' S. ; long. 141° 26' W. ; depth, 1713 fathoms. 



GLOBIGERINA OOZE : cream colored, granular, quite incoherent ; appears 

 to have been washed ; consists of pelagic and bottom-living Foraminifera, 

 Ostracodes, coccoliths, rhabdoliths; Sponge spicules, Radiolaria; minute 

 particles of felspar, obsidian, and magnetite.
