98 EXl'EDITIOX OF THE "ALBATROSS," 1899-1900. 



red clay was obtained, with either no carbonate of lime or only a trace of 

 it, except at Stations 241 and 247, the deposit of which contained, in the 

 one case 10 per cent, in the other 17-29 per cent of carbonate of lime. At 

 Station 241, lat. 35° 41' N., long. 157' 42' E., in 2300 fathoms, seventy 

 species of Foraininifera were obtained, nearly sixty per cent of which is 

 made up of half a dozen of pelagic species. Nearly fifty species of Radio- 

 larians and twenty-five of Diatoms are also recorded from the deposit at 

 that station. 



At the second station from the Japanese coast (Station 238, lat. 35° 18' N., 

 long. 144° 08' E.), in 3950 fathoms, red clay, the number of species of 

 Radiolarians in the deposit is limited to two, and it only contains fifteen 

 species of Foraminifera. 



At Station 244, lat. 35° 22' N., long. 169 53' E., in 2900 fathoms, red 

 clay, there are mentioned as found in the deposit over thirty species of 

 Foraminifera and nearly 100 species of Radiolarians. 



At Station 245, lat. 36° 23' N., long. 174° 31' E., in 2775 fathoms, red 

 clay, not more than ten species of Radiolarians are recorded as found in 

 the deposit. 



At Station 246, lat. 36° 10' N., long. 178 E., in 2050 fathoms, Globi- 

 gerina ooze, where the deposit contains 56.07 per cent of carbonate of lime, 

 over 100 species of Foraminifera are recorded, and 62 i)er cent of the car- 

 bonate of lime is composed of pelagic species. 



At Station 247, lat. 35° 48' N., long. 179° 57' W., in 2530 fathoms, red 

 clay, ten species of Radiolarians are recorded. A few more species of 

 Radiolarians are recorded at Station 250, lat. 37° 49' N., long. 166° 47' W., 

 in 3050 fathoms, red clay, togetlier with about thirty species of Diatoms. 

 At the next station, in 2950 fathoms, Diatoms were also common. Radio- 

 larians are limited to nine species in the deposit of Station 252, lat. 37" 52' 

 N., long. 160° 17' W., in 2740 fathoms, red clay. 



At the northeasternmost point reached by the "Challenger" in the 

 Pacific (Station 253, lat. 38° 09' N., long. 156° 25' W.), in 3125 fathoms, 

 red clay, forty species of Foraminifera are recorded, four of which are 

 pelagic, while the number of species of Radiolarians has increased to about 

 sixty. On the line due south from Station 253 in the direction of the
