FORAMINIFERA OF NORTH FACIFIC OCEAN.

Distribution. — It is impossible to determine which of the two forms 

 figured by Brady was obtained from the one North Pacific station 

 given by him, Honolulu Reefs, 40 fathoms. However, an examina- 

 tion of Bagg's material labeled B. textilarioides shows the rough 

 bordered form here described. In the Nero material 

 I have had specimens from stations 2068, 2071, and 

 2074 in 307, 271, and 22 fathoms, respectively, the 

 last being at Honolulu. Therefore Brady's specimens 

 were probably of thisspecies. There are also numerous 

 specimens from the southern coast of Japan and 

 from the area between Yokohama and Guam. 



Millett recognized two distinct forms in the Malayan 

 material. This spinose or granular form, at least in 

 the North Pacific, seems to be the more common, no 

 specimens which could be assigned to Reuss's species 

 being seen.

Description.— Test broad, tapering to the rounded 

 apical end; apertural end oblicjuely truncate, com- 

 pressed, the edges thick and square, or somewhat 

 rounded; chambers numerous, the sutures indistinct, 

 the surface ornamented with a series of rounded bosses, arranged 

 more or less in vertical rows and also in oblique rows across the 

 test; aperture rounded, with a raised border; color white. 

 Length 0.50 mm. 



Distribution. — The only records for this species are 

 those given by Brady from off Juan Fernandez in 

 the South Pacific. What certainly seems to be this 

 species has occurred at Albatross station D4839, in 

 140 fathoms, off Japan. The form is similar and the 

 surface has the peculiar raised ornamentation shown 

 in Brady's figures.
