Description
editThe length of the shell varies between 1.5 mm and 3 mm.
The thin shell is hyaline. It is dark brown or fulvous. It has distant thin longitudinal, and stronger, more distant spiral lirae, two of the latter in the penultimate and five in the body whorl; perforate. The outer lip is thin. [2]
Distribution
editThis species occurs in European waters (off the Azores) and rare in the Mediterranean Sea (off Sicily and Greece).
Fossils were found in Pliocene strata near San Miniato, Italy.
