Station c9/.— 2,908 fathoms. Red c•la\^ Mostly "fine wash- 

 ings;'"' a few minute radiolaria and mineral particles. No calcareous 

 organisms. 



Station 93. — 1,463 fathoms. Globigerina ooze. Light grayish- 

 brown. Broken shells of foraminifera; few complete ones. No 

 coccoliths. Nodules of manganese; many rather coarse mineral 

 fragments. 



Station 100. — 2,552 fathoms. Red clay. Fawn colored. Foram- 

 inifera few and much broken; no other organic remains. Coarse 

 volcanic sand in large proportion. 



Station 106. — 2,002 fathoms. Specimen consists of three manga- 

 nese-iron nodules, the largest about 12 millimeters in diameter. This 

 is as large an object as the opening in the sounding cup would admit. 

 The finer material was washed out of the cup during its return to 

 the surface, the closure of the valve having been prevented by the 

 nodules. 



Station 110. — 2,655 fathoms. Red clay, A few foraminifera. No 

 other organic remains. Very small mineral sediment, principally 

 volcanic glass. 



Station 12Jf. — 1,726 fathoms. Globigerina ooze. Color, grayish- 

 white. Sediment almost exclusively composed of foraminifera: 

 Orbulina^ Glohigerlna, Palvinulina, Folystomella., VerneuUina, Erlien- 

 hergina {hystrix)., the latter rather frequent. Few mineral particles. 

 A few coccoliths and rhabdoliths. 



Station lliS. — 2,230 fathoms. Globigerina ooze. Color, brownish- 

 white. Foraminifera: Glohigerina., Pulvinulina., Rotalia., Ehren- 

 hergina (Jiystric). Coccoliths; no radiolaria or diatoms. Nodules of 

 phillipsite; decomposed pumice, coarse and fine. 



Station 1"26.— 2,627 fathoms. Red clay. Although this station is 

 onh^ 5 miles distant from the last, the foraminifera have entirely dis- 

 appeared, and the deposit shows only amorphous matter, an occa- 

 sional radiolarian, and a few mineral fragments. 



Station 152. — 3,026 fathoms. Red clay. Only a few particles 

 larger than 0.3 millimeter. A single fragment of an arenaceous 

 foraminifera {Pmmmosphxra fusca). No calcareous organisms. 

 Fragments of large radiolarian (Oroplegma), Minute manganese 

 concretions. Fine sand. 



Station 163.— 2;Q()'^i'A.thomB. Red clay. Fawn colored. No foram- 

 inifera; many radiolaria; few diatoms; sponge spicules. Mineral 

 fragments very small in size and quantit3^ 



Station 165. — 2,135 fathoms. Globigerina ooze. Color, pale yel- 

 lowish-brown. Sediment principally pelagic foraminifera; many coc- 

 coliths. Few mineral fragments. 



Station 166 to 77^.-1,593 to 2,111 fathoms. Globigerina ooze. 

 Color varies from nearly white to pale yellowish-brown, according to
