 pelagic and bottom-living Foraminifera, small Lamellibranchs and Gaster- 

 opods, Pteropod fragments, Heteropods, otoliths, Ostracodes, Echinoid spines, 

 Tunicate spicules, coccoliths, rhabdoliths ; Sponge spicules; fragments of 

 obsidian, the largest about 5 mm. in length, and palagonite, highly scori- 

 aceous, the vesicles lined with a purple colored material, and the outside 

 of the pieces black and glassy, coated with manganese, the largest fragment 

 nearly 4 ram. in length.
