Nodosaria scalaris, var. separans H. B. Brady, Rep. Voy. Challenger, Zoology, 

 vol. 9, 1884, p. 511, pi. 64, figs. 16-19. 



Description. — Variety with the last-formed chambers, one or more, 

 remote, the neck of the previous chamber exposed between, the 

 early chambers also often less inflated than in the typical. 



Distribution. — This variety occurred at the following Albatross 

 stations: D5201, in 544 fathoms (987 meters), Sogod Bay, southern 

 Leyte, bottom temperature 52.8° F. (11.5° C); D5254, Gulf of Davao, 

 28 fathoms (51 meters), no bottom temperature; D5282, in 248 

 fathoms (454 meters), China Sea, off southern Luzon, bottom tem- 

 perature 47.4° F. (8.5° C.);D5630, in 569 fathoms (1,040 meters), 

 south of Patiente Strait, and D5650, Gulf of Davao, 540 fathoms 

 (988 meters), bottom temperature 40.1° F. (4.5° C). 



The variety seems usually to be far less widely distributed than is 

 the typical form.
