Florida. The other records for this species are in this same general 

 region, the Bahamas, and off the northeast coast of Brazil. This is 

 evidently the species referred to by Goes in the reference above, but 

 the species differs from B. dilafata in the smaller size, shorter form, 

 and the peculiar configuration of the outline of the chambers. It is 

 evidently, from the records, a species of the general West Indian 

 region.

Heron- Allen and Earland record this species from the Clare Island 

 region and from the western coast of Scotland. It was originally 

 described by d'Orbigny from the coast of Cuba, and there are no 

 further recent records except these. As noted by Heron-Allen and 

 Earland, the specimens from the British Isles are not entirely typical.

Z?escnpfio7i.— "Test wedge-shaped, consisting of five to nine pairs of 

 chambers rapidly increasing in breadth and thickness, so that the 

 terminal portion of the shell is comparatively inflated. Marginal 

 edges, rounded, sutures slightly depressed. Aperture somewhat 

 variable, at times regularl}^ textularian, but usually bolivine, situate 

 at the extremity of the terminal chamber. Surface hyaline, coarsely 

 punctate, somewhat rough. Average breadth, 0.12-0.15 mm. 

 Average length, 0.17-0.25 mm. Average thickness of oral extremity, 

 0.1 mm."
