102 EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
deposits at Stations 299, 2160 fathoms; 300, 1570 fathoms; 302, 1450 
fathoms, accompanied by a small number of Radiolarians. At Station 300 
there are over 140 species of Foraminifera found in the deposit and 
nearly fifty species of Radiolarians. Only five of the species of Foram- 
inifera are pelagic, yet they make up 83 per cent of the carbonate of 
lime which constitutes over 54 per cent of the deposit at that station. 
The Surface Organisms observed by the “ Challenger” in the Pacific. 
A comparison of the surface animals taken from the records of the 
“ Challenger” with those obtained by the “ Albatross”? can at present 
only show in a very general way their distribution. 
The observations of the “Challenger” have not as yet been tabulated 
with reference to the geographical range of the surface organisms.’ It 
is hoped that a beginning may be made when the records of the present 
Expedition of the “ Albatross” are properly arranged. It will be practi- 
cable, then, to give some general idea of the distribution of such types as 
the transparent Annelids, the Pteropods, the Salpz, and other Tunicates, the 
pelagic fishes, and Cephalopods. But by far the greatest mass of material 
relating to surface animals consists of the pelagic Crustacea, the greater 
number of which consist of the Copepods; next come the Schizopods and 
Macrurans, the Brachiurans being comparatively few in number. The 
Ostracods are also fairly numerous. From a cursory examination we can 
state that the surface fauna of the tropical Pacific has a very wide geograph- 
ical range, a great many of the species reaching from the coasts of Central 
America to the shores of the western Pacific. 
On the “Challenger” line, Admiralty Islands to Japan, at Station 220, 
lat. 0° 42’ S., long. 147° E., the surface haul was characterized by Diatoms, 
Globigerinse, Dyphies, Siphonophores, Sagitta, Alciopa, Saphirina, Copepods, 
Hyperia, Oxycephalus, Lucifer Zoés, Pteropods, Appendicularia, Salpex, 
Doliolum, and young fishes. 
At Station 221, lat. 0° 48’ N., long. 148° 41’ E., red clay, in 2650 fath- 
oms, a number of Diatoms were obtained from the surface, as well as 
Globigerinz, Schizopods, Macrurans, Cephalopods, young fishes, and much
