Test elongate, subcylindrical, the apex bluntly pointed; chambers 

 numerous, inflated, the sutures fairly deep, the surface smooth except 

 the portion at and just above the sutures, which is minutely spinose 

 or granular; aperture large, loop-shaped, with a slightly raised border. 

 Length, 0.50-0.75 mm.; breadth, 0.15 mm.; thickness, 0.12 mm. 



This species occurs at numerous Albatross stations, data for which 

 are given in table 12.

Bolivina capitata Cushman, Contr. Cushman Lab. Foram. Res., vol. 9, p. 80, 

 pi. 8, figs. 12a, b, 1933; Cushman Lab. Foram. Res. Special Publ. No. 9, 

 p. 146, pi. 19, fig. 29, 1937. 



Test elongate, about 3 times as long as broad, tapering gradually 

 from the subacute initial end to the somewhat swollen apertural end, 

 periphery rounded and somewhat lobulated; chambers numerous, 

 distinctly inflated, especially toward the apertural end; sutures dis- 

 tinct, depressed, strongly oblique; wall smooth, nearly transparent, 

 finely perforate; aperture broadly elliptical, sometimes tending to 

 become terminal. Length, up to 0.50 mm.; breadth, 0.15 mm.; 

 thickness, 0.10 mm. 



It has occurred rather commonly at the shallow water stations: 

 12 and 24 fathoms off Nairai, Fiji, and 12 fathoms off Levuka, Fiji. 

 Specimens were also obtained from 7 fathoms off Rotonga. 



BOUVINA GLOBULOSA Cushman

Bolivina globidosa Cushman, Contr. Cushman Lab. Foram. Res., vol. 9, p. 80, 

 pi. 8, figs. 9a, h, 1933; Cushman Lab. Foram. Res. Special Publ. No. 9, 

 p. 146, pi. 19, fig. "30, 1937. 



Test small, elongate, tapering gradually from the subacute initial 

 end to the greatest breadth formed by the last two chambers, periphery 

 rounded; chambers inflated, more or less globose, increasing rather 

 uniformly in size as added; sutures distinct, depressed, somewhat 

 sigmoid, slanting backward but a small amount from the horizontal; 

 wall smooth, finely perforate; aperture comparatively large, at the 

 base of the last-formed chamber and forming a loop-shaped opening. 

 Length of holotype, 0.70 mm.; breadth, 0.40 mm.; thickness, 0.15 mm. 



The type is from Albatross station H3786, lat. 12°07'00" N., long. 

 137°18'00" W., m 2,883 fathoms. It. br. rad. oz. 



This is a small species but is rather widely distributed in the Alba- 

 tross collections. It has usually not occurred in any considerable 

 numbers at any particular station. The data for these are given in 

 table 13. No specimens were found at any of the shallow-water 

 stations about the various islands.
