102 EXl'EDITION OF THE "ALBATROSS," 1890-1900. 



deposits at Stations 299, 2160 fathoms; 300, 1375 fathoms; 302, 1450 

 fathoms, accompanied by a small number of Radiolarinns. 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 de'posit at that station.

A comparison of the surface animals taken from the records of the 

 "Challenger" with tho.se obtained by the "Albatross" can at present 

 only show in a very general way their distribution. 



The ob.servations 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 jje practi- 

 cable, then, to give some general idea of the distribution of such types as 

 the transparent Annelids, the Pteropods, the Salp«, and other Tunicates, the 

 pelagic fishes, and Cephalopods. But by far the gi-eatest 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 nundjer. 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, 

 hit. 0' 42' S., long. 147' E., the surface haul was characterized by Diatoms, 

 Globigerina3, Dyphies, Siphonophores, Sagitta, Alciopa, Saphirina, Copepod.s, 

 Ilyperia, Oxycephalus, Lucifer Zoea), Pteropods, Appendicularia, Salpse, 

 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 

 Globigerinoe, Schizopods, Jfacrurans, Cephalopods, young fishes, and much
