100 EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
the latter deposit containing over ninety species of Foraminifera, no less 
than eighteen of which are pelagic and make up 86 per cent of the deposit. 
Yet at this station nearly 600 species of Radiolarians are recorded by 
Haeckel as occurring in the deposit, and about thirty species of Diatoms. 
The station south of the equatorial belt (272, lat. 3° 48’ S., long. 152° 56° W., 
in 2600 fathoms) also contained 10.19 per cent of carbonate of lime, and 
Station 273, lat. 5° 11’ S., long. 152° 56’ W., in 2350 fathoms, still further 
south, only 2 per cent; the number of species of Radiolarians occurring in 
the deposit at Station 272 being reduced to about 270 in number and to 
about 110 at Station 273. At Station 274, lat. 7°25’ S., long. 152° 15’ W., 
the carbonate of lime is nearly 4 per cent and the Radiolarians in the 
deposit number over 175 species. 
In 2350 fathoms, Station 276, lat. 13° 28’ S. long. 149° 30’ W., there is 
28.28 per cent of carbonate of lime in the red clay, and over 110 species 
of Foraminifera, sixteen of which are pelagic and make up 88 per cent 
of the carbonate of lime. Station 277, in 2325 fathoms, has over 9 per cent 
of carbonate of lime. Station 278, lat. 17° 12’ S., long. 149° 43’ W., 1625 
fathoms, over 20; and other stations in the vicinity of the volcanic mud 
contain a varying amount of carbonate of lime. At Station 279 it con- 
tains nearly sixty species of Foraminifera, four of which are pelagic and 
make up 33 per cent of the carbonate of lime. 
On the line from Tahiti to Valparaiso the soundings (Stations 281-282) 
in red clay south of Tahiti, though not more than 2450 fathoms in depth, 
show but a trace of carbonate of lime, while the soundings to the east- 
ward, somewhat less in depth but in Globigerina ooze, carry from 65 to 
26 per cent, and are in the line of the southeast trades (Station 283, lat. 
oe 09 8, long. 145 17% W. 10-286, int. 33. 29 8, lone. 185°: 27° W.). 
There are nearly forty species of Foraminifera recorded from the deposit 
of Station 280, south of Tahiti in 1940 fathoms, thirteen of which are pelagic 
species, making up 84 per cent of the carbonate of lime, and at Station 284, 
lat. 28° 22’ S., long. 141° 22’ W., there are eighty species noted as found 
in the deposit in 1985 fathoms, sixteen species of which are pelagic, mak- 
ing up 74 per cent of the carbonate of lime, which constitutes 65 per cent 
of the deposit. In a somewhat deeper station, 285, lat. 32° 36’ S., in 2375
