106 EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
genera occur, of course, in different combinations both in number of species 
and abundance of specimens at the stations occupied, but none of them 
were very marked types, or types which had not a wide geographical 
distribution in the tropical Pacific, as can be noted by comparing the 
above list with the notes of the contents of the surface hauls made by the 
“ Albatross” in a nearly parallel line, but several hundred miles to the 
eastward. 
As has been shown, p. 94, from the examination of the bottom deposits, 
a large number of pelagic Foraminifera were obtained by the “ Challenger” 
on the line Tahiti to Valparaiso, as well as pelagic Radiolarians. Going 
south from Tahiti, the “ Challenger” obtained three species of Radiolarians 
on the surface at Station 282, lat. 23° 46’ S., long. 149° 59’ W., seven at 
Station 284, lat. 28° 22’ S., long. 141° 22’ W., and no less than forty-two 
at Station 288, lat. 40° 03’ S., long. 132° 58’ W., the point at which the 
“Challenger” turned east toward Valparaiso, distant nearly 3000 miles. 
Along that line which runs somewhat north of the current setting east, 
in a somewhat higher latitude, the number of surface Radiolarians collected 
was quite remarkable. At Station 289, lat. 39° 41’ S., long. 131° 23’ W., 
seven species are enumerated, four from Station 290, lat. 39° 16’ S., long. 
124° 07' W., eighteen at Station 291, lat. 39° 13’ S., long. 118° 49’ W., the 
same number at Station 295, lat. 38° 07’ S., long. 94° 04’ W., and five at 
Station 297, lat. 37° 29’ S., long. 83° 07’ W. 
The other surface organisms found by the “Challenger” going south 
from Tahiti to Station 288, in lat. 40° 03’ S., consisted of Pteropods, Dia- 
toms, Hastigerina, Acanthometre and other Radiolarians, Siphonophore, 
Ctenophoree, Echinoderma larvee, Sagitta, Cyprinida, Saphirina, Copepods,} 
Euphausia, Sergestes, Lucifer, Atlanta, Appendicularia, Scopelids, Halobates, 
Clio, Coccospheres, Rhabdospheres, Globigerinz, Alciopa, Tomopteris, Salpee, 
young Lamellibranchs, Phronimids, Hyperids, Stomapod larvee, Thysano- 
poda, Benthocaris, Medusa, Ostracods,” Amphipods, Schizopods, Doliolum, 
Scopelids. ; 
On the line from Station 288 to Valparaiso the surface organisms, other 
1 The Copepods increased as the ‘¢ Challenger” went south from Tahiti. 
2 The number of Ostracods at Station 296, lat. 38° 06’ S., long. 88° 02’ W., is very striking.
