described from off Florida and which has been reported thus far only 

 from the West Indian region. 



In the Pacific, another species, bearing considerable resemblance 

 to the present specimens, was described as Discorbis globularis 

 (d'Orbigny) var. bradyi (Cushman, 1915, p. 12) and reported from 

 off Japan and off Hong Kong. It differs, however, in the final whorl 

 being composed of 5 or 6 chambers that are not elongate and arcuate 

 in shape. As a result, the tests are elongate in outline, not circular 

 as are those of the present specimens.

This conical species is distinguished by the upturned outer edges 

 of the chambers, which look like a series of ruffles around the dorsal 

 surface. The species is very rare.

This species has a high conical form with the concave basal part 

 ornamented by fine striations radiating out from the central 

 umbilicus. 



Specimens are rare and found only in samples from around the 

 atolls.
