 itial end broadly rounded, apertural end slightly produced; cham- 

 bers comparatively few, inflated; sutures distinct and somewhat de- 

 pressed; wall smooth; aperture radiate. 



Length up to 0.90 mm. 



Distribution. — There are numerous records for this species from 

 the eastern Atlantic, and Flint has recorded it off the coast of 

 Georgia. I have had specimens from three Albatross stations which 

 may be referred to this species. They are from off the coasts of 

 Georgia and Florida.
