Shell ovate conical, thin, translucent and shining. Apex broken but apparently acicular. Remaining whorls nine, of which the latter are markedly tumid and narrow, giving the shell a squeezed or telescoped aspect. The upper whorls are smooth and polished, the lower gradually acquire an oblique, longitudinal sculpture which becomes coarser as the shell proceeds and finally on the page 412last half whorl rise into sharp varices; on the latter three whorls several weak spiral threads reticulate the transverse growth lines and create angles below the suture and the periphery. Aperture very oblique, lip sharp, sinuous, reflected, effuse anteriorly, columella broad, arched, and reflected over a minute perforation. Length 11, breadth 61/2 mm.
