PRELIMINARY REPORT. 99 
Hawaiian Islands, fifteen species of Foraminifera, three of which are pelagic, 
and eight species of Radiolarians are recorded from Station 256, lat. 30° 22’ N., 
long. 154° 56’ W., in 2950 fathoms, red clay, and in forty fathoms, off the 
Honolulu reef, eighty-two species of Foraminifera are recorded in the de- 
posit, only 3 per cent of which is made up of seven pelagic species. 
The line from Yokohama east to Station 253, lat. 38° 09’ N., long. 
156° 25’ W., and thence south to the Hawaiian Islands, is marked for the 
great number of Radiolarians recorded in the deposits of the different 
stations, as well as for the number of surface Radiolarians. It will be 
noticed that the above line follows the general trend eastward of the 
Japanese current and that the fauna of the bottom appears to be far 
more abundant in the track of this great oceanic current than in the line 
running south of Japan, where no great oceanic currents occur. 
On the “Challenger” line, Hawaii to Tahiti, which corresponds more to 
the “ Albatross” line, only two of the soundings (Station 270, lat. 2° 34’ N., 
long. 149° 09’ W., and 271, lat. 0° 33’ 8, long. 151° 34 W.) indicate Globi- 
gerina ooze, and both of them are far beyond the depth at which such 
deposits are usually met with. The “ Albatross” had a similar experience 
at Stations 14, lat. 6° 41’ N., long. 137° W., in 2776 fathoms; 16, lat. 2° 38’ N., 
long. 137° 16° W.; 17, lat...0° 50’ N., long. 187° 54’ W., in 2440 and 2463 
fathoms. The above-mentioned soundings of the “Challenger”? were in 
2925 and 2425 fathoms, and both in the belt of the equatorial current. 
With the exception of the stations nearest the Hawaiian Islands and 
Tahiti, which showed a deposit of volcanic mud (Stations 262, 263, and 
278), the other stations on that line were all red clay, with little or no 
trace of carbonate of lime. Though Station 269, lat. 5° 54’ N., long. 
147° 02’ W., in 2550 fathoms, approaching Stations 270, lat. 2° 34’ N., long. 
149° 09’ W., and 271, lat 0° 33’ S., long. 151° 34’ W., contained 20 per cent 
of carbonate of lime, made up of more than thirty species of Forami- 
nifera, seven of which were pelagic species, composing about 85 per cent 
of the carbonate of lime; the rest of the deposit consisting of over sixty 
species of Radiolarians and over eighty species of Diatoms. 
Of the Globigerina ooze Stations No. 270, 2925 fathoms, contained 71.47 
per cent of carbonate of lime, and 271, in 2425 fathoms, over 80 per cent;
