The species seems to be confined to the Philippine Archipelago 

 proper as far as the material examined shows, and to warm waters. 

 The depths range from 26 to 554 fathoms (48 to 1,012 meters), with 

 the average 129 fathoms (236 metei-s), and the bottom temperatures 

 from 52.4° to 63.1° F. (11.3° to 17.2° C), average 57.2° F. (14° C). 

 At the deepest station, 554 fathoms (1,012 meters), the bottom tem- 

 perature was 52.8° F. (11.5° C), a high temperature for this depth.

Nodosaria spirostriolata Cushman, Proc. U. S. Nat. Mus., vol. 51, 1917, p. 656. 



Description. — Test much elongate, very slightly tapering toward 

 the initial end, which is broadly rounded, chambers numerous, 

 short, elliptical in side view, sutures but slightly depressed, surface 

 ornamented throughout with numerous (40-50) fine longitudinal 

 costae, spirally arranged ; apical end without a neck, broadly rounded. 



Length 10 mm. 



Distribution. — Type specimen (U.S.N.M. No. 9119) and others 

 from Albatross station D5236, in 494 fathoms (903 meters), Pacific 

 Ocean, east coast of Mindanao, bottom temperature 41.2° F. (5.1° C). 

 It has also occurred at D5178, off Romblon, 78 fathoms (143 meters). 



This is a large and strildng species, with its ver}^ numerous fine 

 spiral costae giving it a unique appearance.
