ORIGINAL DESCRIPTION. — T. testa elongato-turrita , per longitudinem paulo convexa, omnino fusca, apice acuminata; anfractibus tredecimis, angustis, lente crescentibus, sutura profunda junctis, trifariam transversim, inaequilater granulosis, ultimo anfractu brevi, ad peripheriam subangulato, basi depresso, bisulcato; apertura circulari, canali breviusculo, aperto, obliquo, terminata.

DIAGNOSIS. — Shell cyrtoconoid with flat sides. Neotype 5.9 mm high. Teleonconch of 12 whorls. Three spiral cords present, the second appearing on the seventh whorl. Cords with tubercles at the intersection with slightly prosocline axial ribs. Second cord initially as a fine thread, then developing tubercles. Peristome without additional cords. Base with three additional smooth or weakly tubercled spiral cords. No visible microsculpture in interspaces. Multispiral protoconch of c. 4 whorls bearing one strong spiral keel and several equally strong axial riblets on the second to fourth whorl.
