Description
Original description: "Elongated cone shaped shell, not very robust, whitish coloured. Heterostrophic protoconch with sunken nucleus, sculptured spirally by 4/5 marked cordlets. Teleoconch made up of 3/4 rather convex whorls with an incised suture; these whorls are sculptured axially by slightly wavy prosocline riblets of about the same width as the interspaces. On the body whorl there are 25/30 riblets which extend right up to the base; in adult specimens they are more numerous and closer together. One or, more rarely, two spiral cordlets are present on the superior whorls; always two, well spaced, on the body whorl. Round quadrangular mouth with visible columellar tooth on the inside. Umblical slit evident in adult specimens. Maximum dimensions: height 2 mm. Diameter 1 mm. Operculum and soft parts unknown."[4]
