PRELIMINARY REPORT. 101 



fathoms, red clay, and with 2G.25 per cent of carbonate of lune, 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 Peiias the Globigerina ooze is marked 

 again for the great number of species of Foraminifera recorded from the
