pointed; initial end and angles of chambers often with sharp spines; 

 walls of medium thickness, hyaline, or in some cases thickened and 



rough, perforate, smooth or granular; aper- 

 tural end of test bluntly angled, the edges of 

 the chambers thickened; aperture a curved 

 slit at the base of the inner edge of the 

 chamber. 



Length 0.25-0.75 mm. 



Distribution. — This species seems to be 

 widely distributed in the North Pacific. 

 Brady records it from four Challenger stations 

 in this area, the extremes of depth being 7 

 and 2,300 fathoms. Rhumbler notes its oc- 

 currence at Laysan Island, and Bagg records 

 it from five Albatross stations near the Ha- 

 waiian Islands in from 275 to 865 fathoms. 



I have had material from a considerable 

 number of stations in the North Pacific, all 

 but two of which were from depths greater 

 than 100 fathoms. Brady found that but 

 7 of his 24 stations for this species were in 

 depths greater than 100 fathoms. The great- 

 est depth at which material was taken in- 

 cluding this species was 1,355 fathoms in the Nero soundings near 

 the Hawaiian Islands. Nearly all the speci- 

 mens examined were from south of 30° 

 north.

Description. — Test affixed, pyramidal, 

 tapering to a rather acute point at the 

 apical end, triserial except at the attached 

 end, which may be biserial in the attached 

 chambers; test usually somewhat curved; 

 wall coarsely arenaceous, but only slightly 

 roughened on the surface; aperture at the 

 base of the inner margin of the chamber in 

 an elongated depression formed by the last 

 formed whorl of chambers, rounded or some- 

 what elongate; color reddish brown, except the attached chambers 

 and the area of attachment about the chambers, which are light gray. 



Length up to 4 mm.
