can hardly be distinguished from typical N. pynda in much of the 

 material, all gradations existing between the two extremes and 

 also toward the following variety. 



At numerous stations throughout the Philippine Archipelago this 

 variety has occurred usually with the typical form. The depths range 

 from 83 to 554 fathoms (151 to 1,012 meters), average 302 fathoms 

 (552 meters), the bottom temperatures range from 41.2° to 63.6° F 

 (5.1° to 17.5° C), average 52.2° F. (11.2° C).

NODOSARIA PYRULA d'Orbigny, var. LONGI-COSTATA Cushman. 



Plate 3.3, figs. 8, 9. 



Nodosaria pyrula d'Orbigny, var. longi-costata Cushman, Proc. U, S. Nat. Mus., 

 vol. 5, 1917, p. 653. 



Description. — Variety with the whole of the chamber body or- 

 namented by longitudinal costae, even connecting across the connect- 

 ing necks ; aperture with the costae running to the edge of the opening. 



Distribution. —Type specimen (U.S.N.M. No. 9108) from Albatross 

 station D5388, in 226 fathoms (414 meters), between Burias and 

 Luzon, bottom temperature 51.4° F. (10.7° C). In addition to the 

 type station the variety occurred at the following stations, often in 

 considerable numbers: D5201, in 554 fathoms (1,012 meters), Sogod 

 Bay, southern Leyte, bottom temperature 52.8° F. (11.5° C.) ; D5214, 

 in 218 fathoms (399 meters), east of Masbate Island, bottom tem- 

 perature 51.4° F. (10.7° C); D5259, in 312 fathoms (571 meters), 

 off northwestern Panay, bottom temperature 49.3° F. (9.6° C.) ; 

 D5311, in 88 fathoms (161 meters), China Sea, off Hongkong; 

 D5338, in 43 fathoms (78 meters), Palawan Passage; D5371, in 83 

 fathoms (151 meters), off Marinduque Island, and D5537, in 254 

 fathoms (464 meters), between Negros and Siquijor, bottom tem- 

 perature 53.5° F. (11.8° C). 



This variety is found in company with var. semirugosa d'Orbigny, 

 but seems distinct in form as well as in ornamentation.
