FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 315 



Throughout the region, both in the Archipelago and in the region 

 to the south, this species occurs, but usually is represented by but 

 few specimens at any station. The stations range in depth from 88 

 to 1,560 fathoms (161 to 2,853 meters), with the average depth 490 

 fathoms (897 meters), and the bottom temperatures from 39.2° to 

 56.4° F. (4° to 13.5° C), the average being 46.8° F. (8.2° C). 



In the region to the southward of the Archipelago proper the species 

 occurs in Sibuko Bay, Borneo; Gulf of Tomini; Molucca Passage; 

 south of Bouro Island; Molucca Sea; Gulf of Boni; Flores Sea; and 

 Macassar Strait.

This species has been noted at but few stations, all but one (Darvel 

 Bay, Borneo, Do580) in the Archipelago proper. In depth these 

 stations range from 23 to 334 fathoms (42 to 611 meters), the average 

 depth being 193 fathoms (353 meters). Bottom temperatures 

 range from 50.5° to 63.1° F. (10.2° to 17.2° C). 



The stations at which this occurs are near Jolo, D5145; between 

 Burias and Luzon, D5216, 5217; Verde Island Passage and Batangas 

 Bay, D5268, 5269; China Sea, D5301; east coast of Luzon, D5446; 

 and north of Tawi Tawi, D5572.
