« A small species, about half an inch long, very taper and slender, thin and transparent, extremely smooth and glossy, of a light horn colour, with a few slight spiral streaks, sometimes opake white, sometimes red, especially at the commissures of the spires, and well distinguish their separation. The mouth is oblong. The spires about ten, all level, or not prominent, and tapering to a very fine sharp point; they are well distinguished by the spiral white lines. » – E. M. da Costa: Hist. Nat. Test. Britanniae, London 1778.

Notice the scar, 270° above the aperture. It draws the place of an ancient labial margin, and matches exactly the profile of the current one. « The origin of these scars is the almost periodic growth of the Eulimidae shell: the animal alternates a phase of rapid growth of the shell (from 0.3 to 1.5 revolutions) with one of stagnation of the growth itself, during which the external lip thickens, thus giving rise to that “scar” when a new phase of growth occurs. » – Gruppo Malacologico Livornese: Eulimidae Mediterranee, august 2001.
