Miliolina durrandii Millett, Jonrn. Roy. Micr. Soc, 1898, p. 268, pi. 6, figs. 

 7-10. — Heron-Allen and Earland, Trans. Zool. Soc. London, vol. 20, 1915, 

 p. 565, pi. 42, figs. 11-16. 



This species was originally described by Millett from the Malay 

 Archipelago, and is recorded by Heron-Allen and Earland from the 

 Kerimba Archipelago, where it is "generally distributed and often 

 quite common." They also record it from the coasts of Burmah, 

 Queensland, Java, and Macassar, as well as from Tahiti. It there- 

 fore has a widespread tropical distribution in the Indo-Pacific in 

 shallow water. 



The few Philippine specimens are all of 50 fathoms (91 meters) 

 of water or less, including the following stations: Tacloban Anchor- 

 age; China Sea, off southern Luzon; off eastern Panay; and between 

 Marinduque and Luzon.

From large series dredged at several stations, showing the 3"oung 

 of this species, it is evident that it is a species of Massilina, instead 

 of Spiroloculina. The finely granular condition of the surface is very
