« Shell subulate, extremely sharp and smooth, shiny, thin, hyalin; whorls 8, flat, contiguous; aperture narrowly lanceolate, the upper part acuminate; labrum strongly protruding; margin thickened by a smooth varice that overlies [this is the columellar callus] the umbilical slit ; adorned by cinnamon spots and dots. » – S. Brusina: “Gastéropodes nouveaux de l’Adriatique”, Journal de conchyliologie vol. XVII, Paris 1869, p.245.

Brusina: « This species is closer to L. bilineala Alder (of which I also collected some samples at Punte Bianche), than L. subulata Donovan. It differs from both, at first by its smallness, then by the varix of its columella, by the notable dilatation of its external margin and by its colouring. After discovering this shell, I did not know if I was dealing with a real species or a simple variant. Mr. G. Jeffreys told me that the species was new, as soon as he saw it in my collection. Therefore I beg him to allow me to give this new form his name, so highly placed among the English malacologists. »
