Distribution. — Brady records this species from a single North 

 Pacific locality, Challenger station 260A in 40 fathoms off the coral 

 reefs of Honolulu, Hawaiian Islands. Bagg records it also from the 

 same region at a single Albatross station D4017 in 305 fathoms. 



In the Nero material it has occurred at a number of stations in the 

 vicinity of the Hawaiian Islands, especially about Waimea Bay. It 

 also occurred in the Nero dredgings from Guam. Off the southern 

 coast of Japan it has occurred a few times in the shallower warmer 

 waters in the southern part, especially Albatross H4881 in 316 fathoms 

 in Colnett Strait. From the North Pacific Exploring Expedition, 

 Captain Rodgers, there are specimens from Gaspar Straits. 



The following variety seems worthy of notice: 



SPIROLOCULINA GRATA Terquem, var. ANGULATA, new variety.

Spiroloculina grata H. B. Brady (part), Rep. Voy. Challenger, Zoology, vol. 9, 



1884, pi. 10, figs. 22, 23. 

 Spiroloculina nitida (Striate variety) Millett, Journ. Roy. Micr. Soc., 1898, p. 2G6. 



Description. — Variety differing from the typical in having the 

 chambers angular instead of circular in transverse section and the 

 costae parallel to the peripheral margin of the chamber instead of 

 oblique as in the typical, in extreme forms with the periphery hav- 

 ing a decided keel. 



Distribution. — Type-specimen (Cat. No. 9157, U.S.N.M.) fromCebu, 

 Philippines, collected by Dr. E. A. Mearns. Specimens also occurred 

 in shallow water about the Hawaiian Islands in Waimea Bay and off 

 Honolulu. 



The figures given by Brady and referred to here, especially figure 

 23, is very much like that figured here. Millett notes that most of 

 the Malay Archipelago material was of this form. 



Both the typical form and the variety seem to be characteristic 

 of shallow water in the Tropics, especially off coral reefs. 



SPIROLOCULINA ARENARIA H. B. Brady. 



Spiroloculina arenaria H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 153, pi. 8, fig. 12. 



Description. — "Test oblong or oval, complanate; extremities 

 obtusely angular or slightly rounded, peripheral edge rounded; seg- 

 ments few and broad, indistinct externally. Aperture small, circular, 

 with milioline tongue; situated in a slightly produced shelly neck. 

 Exterior sandy; length, one-fifteenth inch (1.7 mm.)." 



Distribution. — From Brady's account of this species it is one of 

 those limited to the East Indian region, occurring from Torres Strait 

 northward to the Philippines. In the North Pacifio the only record 

 is from the Challenger station in the Philippines in 95 fathoms.
