 BILOCULINA MILLETTII Cnshman. 



Miliolina durrandii Millett (part), Journ. Roy. Micr. Soc, 1898, p. 268, pi. 6, 

 figs. 8-10 (not figure 7). — ^Heron-Allen and Earland, Trans. Zool. Soc. 

 London, vol. 20, 1915, p. 565, pi. 42, figs. 11-16. 



Biloculina milleUii Cushman, Bull. 71, U. S. Nat. Mu?., pt. 6, 1917, p. 81, pi. 34, 

 figs. 4, 5. 



This species, described from the Malay region by Millett, and which 

 I also found in Hongkong Harbor, has occurred in the Philippine 

 region at one station. It is evidently characteristic of this rather 

 Hmited region. 



Heron-Allen and Earland record this in their paper from the 

 Kerimba Archipelago, and also note its occurrence "from the coasts 

 of Burma, Queensland, Java, and Macassar in the eastern seas; and 

 in the Pacific is very abundant, and typical at Tahiti." 



This species seems to be without an apertural tooth, none having 

 occurred in our specimen, and Heron- Allen and Earland mention the 

 same characteristic.

Biloculina irregularis d'Orbignt, Foram. Am^r. M^rid., 1839, "Foraminif^ree," 

 p. 67, pi. 8, figs. 22-24.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 

 9, 1884, p. 140, pi. 1, figs. 17, 18. 



This rather widely distributed species in comparatively deep water 

 is recorded by Brady from three South Pacific stations, ranging in 

 depth from 610 to 1,070 fathoms (1,116 meters to 1,957 meters), off 

 Fiji, off Tahiti, and north of New Guinea. Numerous specimens have 

 occurred at a single station in the Philippine dredgings — D5236, 

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

 bottom temperature, 41.2° F. (5.1° C).
