Borsonia hirondelleae is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.^[1]

Description

The size of the shell attains 32 mm, its width : 12 mm. The not very solid, whitish shell has a fusiform shape. The rather high shell is turriculate and contains seven convex whorls, subangular at the periphery, separated by a simple suture. The whorls contain longitudinal, nodulose ribs (13 on the penultimate whorl). The aperture is narrow and is half as long as the length of the shell. The front of the columella is slightly twisted and has a small callus. The outer lip is simple and sharp. It forms a rather narrow sinus. ^[2]

Distribution

This marine species occurs off Morocco, off the Azores and in the Bay of Biscay
