ORIGINAL DESCRIPTION. — Testa solidula, cinereo-violacea, elongatosubulata; anfractibus 18 (primi 3 laevigati, sequentes biseriatim tuberculis [series distantes, suturam obtegentes, tuberculis albescentibus, intervallisque rubro-pictis ornatae] cincti); ultimo seriebus tribus moniliformibus inaequalibusque cincto, ad latus sinistrum et prope suturam tubifero; apertura subrotundata, lateraliter fissa; canali subelongato, recurvo, superne unicarinato; — long. 9, lat. 2 millim. — Varietas minor, long. 5, lat. 1.5 millim.

[Latin diagnosis followed by a discussion in French]

TRANSLATION OF THE LATIN TEXT. — Rather solid shell, purplegreyish, subulate-elongated; 18 whorls (the first three whorls are smooth, subsequent whorls with two series of tubercles [the distant series, hiding the suture, adorned by whitish tubercles interspersed with red ones]; last whorl with three unequal series of moniliform tubercles, tubular on the left side and near the suture; roundish aperture, laterally fissured; slightly elongated siphon, curved, unicarinated above; — length 9, diameter 2 mm.

DIAGNOSIS. — Shell conical with flat sides. Syntypes 7.5 (MNHN-IM-2000-1130) and 4.2 (MNHN-IM-2000-1139) mm high. Teleoconch of c. 13 whorls. Three spiral cords present, the second appearing on the eleventh whorl. First and third cords with tubercles at the intersection with rather prosocline axial ribs. Second cord initially as a fine thread, but developing thin tubercles towards the peristome. Spiral microsculpture of weakly granulate fine threads. Peristome without additional spiral cords. Posterior sinus deep. Base with two additional spiral cords of which the first developing flat tubercles, the second fine and smooth. Teleoconch light violet, interspaces between the tubercles on the spiral threads brown.
