FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 473 



Very fine specimens of this species occurred at Albatross stations 

 D5236, east coast of Mindanao, 494 fathoms (903 meters), and 

 Do277, China Sea, off southern Luzon, 80 fathoms (146 meters). 

 Tiiese are the only Philippine stations; the other stations beins: in

Typical material of this species occurred at but seven stations 

 and only a few specimens at each. These stations range in depth 

 from 10 to 752 fathoms (18 to 1,375 meters), the average depth 350 

 (640 meters); except at one station, at 10 fathoms (18 meters), the 

 least depth is 135 (247 meters), so most of the material is from deep 

 water. Bottom temperatures are given but for three stations, rang- 

 ing from 43° to 49.8° F. (6.1° to 9.8° C). 



The localities for this species include the Sulu Archipelago, off 

 Siasi, off Jolo; Pacific Ocean, east coast of Mindanao; Gulf of Davao; 

 northwestern Panay; and to the southward in the GuK of Tomini, 

 Celebes,
