 and vial 



Small amount of gray sand in 

 snapper; apparently hard bottom. 

 Jaws had not penetrated far. 

 Slight trace of black substance 

 on edge of jaws 



Red clay and sand 



eoliths; numerous manganese particles, some 

 phillipsite and fragments of palagonite, also feld- 

 spar, augite, quartz, magnetite, volcanic glass. 

 Dark chocolate-colored clay, 97 per cent

 fathoms. CaC03 not determined, globigerina ooze. 

 Contains pelagic and benthonic foraminifera, pter- 

 opods, ostracods, echinoid spines, cephalopod 

 beaks, siliceous organisms, many particles of 

 manganese, black volcanic glass and augite andesite

in mechanical analysis, since fine material is very difficult to disperse. Sample contains much phillip- 

 site, also plagioclase feldspar and serpentine (?). 



Sample 28. Coarse sand grades consist largely of broken fragments of pelagic foraminifera, with relative- 

 ly small proportion of unbroken shells, together with numerous benthonic foraminifera, fairly common 

 manganese grains and plant material, rare echinoid spines, sponge spicules and ostracods. Twinned 

 crystals and aggregates of phillipsite are very common in fine sand and silt grades. Finer material is 

 quite flocculent. 



Sample 29. Sand grades consist almost entirely of unbroken shells of pelagic foraminifera, some stained 

 yellowish brown; together with rare benthonic foraminifera (the shells of arenaceous species consist of 

 broken pelagic shells), ostracods, calcareous algae, bryozoa, unidentified remains of calcareous organ- 

 isms, and fragments of Crustacea. Silt and clay grades are very small in amount. 



Sample 30. Sand grades consist principally of rounded and angular aggregates of fine material; also cofn- 

 mon manganese and palagonite grains, some broken shells of pelagic foraminifera, and rare flakes of 

 muscovite and biotite.
