high. Teleoconch of 7-9 whorls. Three spiral cords present, the second appearing on the fifth whorl. First and third cords with tubercles at the intersection with rather orthocline axial ribs. Second cord initially with thin tubercles later becoming larger. Spiral microsculpture of barely visible fine threads. Peristome without additional spiral cords. Posterior sinus shallow. Base with three additional spiral cords, the first and second with tubercles, the third smooth. Multispiral protoconch of 4.5 whorls with one spiral keel and equally strong axial riblets.
