NODOSARIA PERVERSA Schwafier. 



Plate 37, fig. 2. 



Nodosaria perversa Schwaqbr, iVbuara-Exped., Geol. Theil., vol. 2, 1866, p. 212, 

 pi. 5, fig. 29. — H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 

 512, pi. 64, figs. 25-27. 



Description. — Test elongate, subcylindrical, chambers compara- 

 tively few, inflated; sutures depressed, initial end broadly rounded; 

 wall with numerous longitudinal costae, last-formed chambers usu- 

 ally smooth; apertural end with a short neck with a definite phialine 

 lip. 



Length 1 to 1.5 mm. 



Distribution. — Specimens identical with Schwager's species oc- 

 curred at Albatross station D5285, in 272 fathoms (498 meters), 

 China Sea near southern Luzon, bottom temperature 46.5° F, 

 (8° C); and D5311, in 88 fathoms (161 meters), China Sea, vicinity 

 of Hongkong. 



Schwager's specimens were from the Nicobar Islands, the fossils 

 of which, as has already been noted, are closely related to the present 

 foraminiferal fauna of the Philippines. Brady's specimens were 

 from off the Ki Islands, southwest of New Guinea, the fauna of which 

 is also related closely to the fauna of the Philippines. 



The specimens figured by Silvestri are closely allied if not identical 

 with this species. ^^ 



Egger records this species from the west coast of Australia, Chap- 

 man from east of Tasmania in 1,122 fathoms, and Dakin as rare in 

 the Gulf of Manaar, Ceylon."
