Typical specimens of this species occurred at D5236, Pacific Ocean, 

 east coast of Mindanao, 494 fathoms (963 meters), bottom tem- 

 perature 41.2° F. (5.1° C); D5259, off northwestern Panay, 312 

 fathoms (571 meters), bottom temperature 49.3° F. (9.6° C); D5300, 

 China Sea, vicinity of southern Luzon, 265 fathoms (485 meters), 

 and D5601, Gulf of Tomini, Celebes, 765 fathoms (1,399 meters). 



Genus IRIDIA Heron-Allen and Earland, 1914. 



IRIDIA DIAPHANA Heron-Allen and Earland. 



Tridia diaphana Heron-Allen and Earland, Trans. Zool. See. London, vol. 

 20, pt. 12, 1914, p. 371, pi. 36. 



This species, described by Heron-Allen and Earland from the 

 Kerimba Archipelago, has not, so far as I have seen, occurred in its 

 typical form in the Philippine material. There are two specimens, 

 however, which have the thin membrane at the base, and are covered 

 on the upper surface with sand grains and other foraminiferal tests. 

 These may possibly belong to this species. 



They are from D5201, Sogod Bay, southern Leyte, in 554 fathoms 

 (1,012 meters), and D5282, China Sea, off southern Luzon, in 248 

 fathoms (454 meters).
