Characterization (by Bas Kokshoorn): Shell very fragile, moderately slender to broadly conical, white, largest specimen reaching 38.4 mm in length. Length/width 1.9-2.3-2.9. Protoconch whorls 3 ½. Protoconch yellowish white, with a brown band along upper part of the whorl. Teleoconch whorls up to 10 ¾ (height 24.5 mm), separated by a deep suture, the whorls not being detached. Teleoconch with unevenly spaced, thin costae, damaged in all examined specimens. Number of costae increases over number of whorls. Costae are orthocline, except near suture where they angle to ophistocline, parallel to columella. Outer margin of costae bend abaperturally over almost whole of their length, except for the ophistocline part, which is erect. Costae not coronate and touch adjoining whorls. Weak spiral lines are present, third teleoconch whorl 9-13-16, fifth 20-33.4-56 (n=10). Third teleoconch whorl with 14-20-28 axial costae, fifth with 14-23.3-37 axial costae (n=9). Five mm width whorl (whorl 4-8) with 18-26.2-34 axial costae. Aperture subcircular, columellar side flattened. Apertural length/shell length 0.3. Umbilicus narrow.
