FORAMINIFERA OF THE NORTH PACIFIC OCEAN. 49 



elongate, irregular, piled up irregularly about a central axis; wall 

 smooth; aperture either a rounded opening at the upper end of the 

 test or with a definite tubular neck. 



Distribution. — Brady figures a fine suite of specimens from off 

 Zamboanga, Philippine Islands, from 102 fathoms. He also found 

 it in material dredged by the Challenger off Honolulu, Hawaiian 

 Islands, in 40 fathoms. The only material of this species I have seen 

 in the present collection is from Nero station 1328 in 871 fathoms off 

 Japan. This is very much like the figures of the young given by 

 Brady. 1

Description. — Test attached, columnar, basal portion usually some- 

 what spreading and buttressed; early chambers arranged in a coiled 

 manner but covered by the later ones which become much inflated and 

 are built up into an irregular, subcylindrical column of a few chambers; 

 wall coarsely porous; aperture often with a tubular neck. 



Length up to 6 mm. 



Distribution. — The only specimens from the North Pacific that I 

 have seen came from Albatross station D4922, in Colnett or Vincennes 

 Strait in 60 fathoms, bottom temperature 79.2 F. This is essen- 

 tially a coral-reef species and it adds another to the considerable list 

 of tropical species of foraminifera which have been noted from this 

 and adjoining stations. 



Genus RUPERTIA Wallich, 1877. 



Rupertia Wallich (type, R. stabilis Wallich), Ann Mag. Nat. Hist., ser. 4, vol. 

 19, 1877, p. 502.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 680. 



Description. — Test attached, columnar; early chambers coiled, 

 later chambers extending up into a coiled column; wall coarsely 

 punctuate; aperture a narrow curved slit at the inner margin of the 

 chamber. 



This genus with the single species here given forms a rather unique 

 modification in the Rotaliidse.
