PRELIMINARY REPORT. 101 
fathoms, red clay, and with 26.25 per cent of carbonate of lime, the 
Foraminifera recorded are reduced to fourteen species, only one of which 
is pelagic and yet makes up 76 per cent of the carbonate of lime. The 
Foraminifera are accompanied by about fourteen species of Radiolarians. 
At Station 286, lat. 33° 29’ S., long. 133° 22’ W., 2335 fathoms, with 25.13 
per cent of carbonate of lime in the red clay, there are sixty species of 
Foraminifera, seven of which are pelagic, constituting 60 per cent of the 
carbonate of lime. 
At Station 288, lat. 40° 03’ S., long. 132° 58’ W., in 2600 fathoms, over 
forty species of Radiolarians are recorded from the surface, only six at 
Station 289 (2550 fathoms), and four at Station 290 (2300 fathoms), nearly 
twenty at Station 291, lat. 39° 13’ S., long. 118° 49’ W., in 2250 fathoms. 
When we come again to the Globigerina ooze stations, containing from 
5 to 71 per cent of carbonate of lime in the deposit, we find nearly sixty 
species of Foraminifera. At Station 293, lat. 39° 04’ S., long. 105° 05’ W., 
in 2025 fathoms, with nearly 45 per cent of carbonate of lime, ten species 
of Foraminifera are pelagic and constitute 78 per cent of the carbonate of 
lime, accompanied by sixteen species of Radiolarians. At Station 295, in 
1500 fathoms, though in 38° south latitude, Juan Fernandez distant nearly 
800 miles, eighteen species of Radiolarians were collected at the surface. 
Five species of surface Radiolarians extended even to Station 298, lat. 
34° 07 S., long. 73° 56’ W., in 2225 fathoms not more than 120 miles 
from Valparaiso; and over twenty-five species of Radiolarians are recorded 
from the deposit of that station in blue mud mixed with over twenty 
species of Diatoms. 
At Station 296, lat. 38° 06’ S., long. 88° 02’ W., in 1825 fathoms, Juan 
Fernandez distant about 500 miles, over eighty species of Foraminifera are 
recorded from the Globigerina ooze, fifteen of which are pelagic and make 
up 85 per cent of the carbonate of lime, of which 64.34 per cent is con- 
tained in the deposit, together with six species of Radiolarians.! 
South of Valparaiso to the Gulf of Pefias the Globigerina ooze is marked 
again for the great number of species of Foraminifera recorded from the
