TRANSLATION OF THE LATIN TEXT. — Elongated and turreted shell, subulate, light violet; fifteen flat contiguous whorls, adorned by two spiral cords of light coloured and equal granules, channelled and distinct suture; short last whorl, narrow, with three granulated spiral cords; rounded aperture, lip laterally deeply fissured. DIAGNOSIS. — Shell conical with flat sides. Teleonconch of 12 whorls. Neotype 6.1 mm high. Two spiral cords present bearing prominent tubercles at the intersection with slightly prosocline axial ribs. A fine spiral thread appearing only on the last whorl under the first cord. Microsculpture of numerous pustulose spiral threads in interspaces. Peristome without additional cords. Posterior sinus well developed and protruding as a very short canal. Base with two additional spiral cords of which the first becomes granulated near the lip and the second smooth. Paucispiral protoconch of c. 2 whorls with one strong spiral keel and low axial riblets. Upper part of the teleoconch pinkish, lower half of the teleoconch pink to light brown with darker interspaces between tubercles on the lower whorls. Protoconch pinkish.

Lot MNHN-IM-2012-36193 contains a fourth specimen that is distinctly different from T. formosus and certainly belongs to another species.
