FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 309 



Specimens of this very distinct variety were obtained at four 

 Philippine stations: Albatross D5164, in 18 fathoms (33 metei-s), 

 Siilii Archipelago; D5191, in 25S fathoms (471 meters,) Tanon Strait, 

 east coast of Negros Island, bottom temperatm-e 62.8° F. (17.1° C); 

 D5217, in 105 fathoms (193 meters), between Burias and Luzon, 

 bottom temperature 63.1° F. (17.2° C); and D534S, in 375 fathoms 

 (686 meters), Palawan Passage, bottom temperature 56.4° F. (13.5° 

 C). The other North Pacific record is the type station in 392 fathoms 

 (717 meters), off the Hawaiian Islands.

This is a pelagic species, at least in part, and its distribution by 

 depth may or may not have a definite significance compared with a 

 truly bottom-living species. It has occurred at six stations in the 

 area — D5192, in 32 fathoms (59 meters), ofl northern Cebu Island; 

 D5236, in 494 fathoms (903 meters), Pacific Ocean, east coast of 

 Mindanao, bottom temperature 41.2° F. (5.1° C); D5243, in 218 

 fathoms (399 meters), Pujada Bay, bottom temperature 63.6° F. 

 (17.5° C.) ; D5257, off southern ^lindanao, eastern Illana Bay; D5551, 

 in 193 fathoms (353 meters), vincinity of Jolo Island, bottom tem- 

 perature 53.3° F. (11.8° C.) ; and D5576, in 277 fathoms (506 meters), 

 north of Tawi Tawi, bottom temperatm'e 53.3° F. (11.8° C). 



In the Challenger Report Brady records this species as pelagic at 

 Zamboanga, Philippine Islands. In the North Pacific it also occurs 

 about the Hawaiian Islands and about Lavsan.
