(Original description) The shell is small and moderately slender, with a nucleus consisting of about two whorls. The aperture aligns with the genus description. The sculpture features narrow axial ribs, between which lie broad spiral bands separated by narrow grooves. The anal fasciole has a swelling adjacent to the suture, which is crudely undulated by obscure prolongations of the axial ribs. [2]
