Shell elevated, small but rather solid, summit overhanging the base, posterior side incurved, anterior steeply sloped. Colour dull white (bleached?). Sculpture: about 20 low spiral ribs arise by interstitial growth, broaden rapidly, denticulate the margin and imprint the interior, the posterior rib dominating its fellows: indistinct growth-striae cross the ribs and their narrow interstices; the whole surface is granulate. The apex is inrolled, of at least one whorl, vertical, with a median sinus. The perforation is a narrow slit, taking the place of two furrows and the posterior rib on the crown of the shell. The interior shelf stretches far down. Aperture oval. Height 2 mm. Aperture 2.2 mm. by 1.6 mm.
