THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 14] 
spines, otoliths, Ostracodes, coccoliths, and rhabdoliths; Sponge spicules, 
Radiolaria; minute particles of felspar, volcanic glass, and magnetite. 
Station 239, 9th February, 1900. 
Three fourths of a mile south of Port Lottin, Kusaie, Caroline Islands; 
depth, 371 fathoms. 
VOLCANIC SAND or MUD: brownish gray, granular, incoherent ; appears 
to have been washed; contains pelagic and bottom-living Foraminifera, 
Kchinoid fragments and spines, Polyzoa, Pteropods, Heteropods, small 
Lamellibranchs and Gasteropods, Coral fragments, otoliths, Ostracodes, 
Tunicate spicules; large amount of mineral particles (almost 50 per cent 
of the material), angular, mean diameter 0.3 mm., augite, a decomposed 
ferro-magnesian mineral (perhaps olivine), volcanic glass, apparently decom- 
posed felspar, magnetite, and manganese grains. 
Station 242, 14th February, 1900. 
Lat. 6° 55’ N.; long. 152° 40’ E. ; depth, 526 fathoms. 
CORAL SAND (?): gray, very little material ; consisting of one or two Coral 
fragments, measuring about 6 mm. in diameter, Mollusc-shell fragments, 
small valve of an Ostrea, Echinoid spines, pelagic Foraminifera. 
Station 247, 20th February, 1900. 
Lat. 11° 35’ N.; long. 147° 15’ E. ; depth, 3213 fathoms. 
RED CLAY: very little material, gritty, incoherent, gray brown in color; 
‘ containing fragments of pumice, the largest being about 10 mm. in length, 
much decomposed, some of the vesicles containing zeolitic crystals; angular 
mineral particles, consisting of volcanic glass, palagonite, pumice, felspar, 
augite, magnetite, and manganese; Sponge spicules, one broken pelagic 
Foraminifer (Spheroidina dehiscens) observed. 
Station 248, 20th February, 1900. 
Lat. 12° 51’ N.; long. 145° 46’ E. ; depth, 4813 fathoms. 
RADIOLARIAN OOZE: this is the deepest sounding obtained by 
the “ Albatross,” and it would have been extremely interesting to have 
had a large sample of the deposit at our disposal, but unfortunately very 
little material was brought up, and it apparently does not represent the 
deposit i situ, being composed almost exclusively of the frustules of one of 
the largest known Diatoms (Hthmodiscus or Coscinodiscus), so that one would
