apertural end; sutures fairly distinct, very slightly depressed toward 

 the apertural end, becoming gradually more oblique as chambers are 

 added; wall smooth, very finely perforate; aperture in the adult 

 terminal, ovate, without a distinct lip. Length, 0.75 mm.; breadth, 

 0.25 mm.; thickness, 0.15 mm. 



The types of this species are from Albatross station H3840, lat. 

 17°21'00'' S., long. 149°15'00" W., in 1,585 fathoms, vol. m. 



While it has not occm-red in any considerable numbers, nevertheless 

 it has been foimd from a number of different stations at which the 

 characters of the species are held rather uniformly. From the records 

 it seems to be a species of comparatively deep water and did not occur 

 in any of the material from the shallow water about the various islands.
