Protoconch not preserved. Teleoconch whorls very weakly convex, twice as wide as high and separated by deep linear suture located immediately abapically to whorl periphery. Transition to convex base rather gradual. Aperture unknown. Teleoconch sculpture consisting of around 13 sharp ridged, low, axially oriented transverse ribs; ribs tapering out at transition to base. Ribs crossed by fine, orthocline to slightly prosocline growth lines and up to around 15 weak and densely spaced spiral striae. Periphery with coarser spiral furrow, marking transition to coarser, scattered spiral striae on base.
