60 THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 
bottom-living Foraminifera, with microscopic scales of calcite, doubtless due 
to the comminution of these shells, a few Echinoid spines, Ostracodes, frag- 
ments of Lamellibranchs and Pteropods. 
ResipvuE: 21.38 per cent, rich red-brown, very clayey : — 
Siliceous Organisms (traces), spherical Radiolaria, Diatoms, and Sponge 
spicules. 
Minerals (traces), a very few angular particles, 0.4 mm. in diameter, 
belonging chiefly to a basic labradorite; pyrites is met with in individuals 
showing sometimes crystalline faces; there are also particles belonging to 
a decomposed ferro-magnesian mineral, greenish, and nearly opaque ; augite 
cannot be identified with certainty. 
Fine Washings (21.38 per cent), practically pure clay, brown and floccu- 
lent, with a very few mineral particles too small for identification, and frag- 
ments of siliceous organisms.
