Shell short, thin, inflated, waxen white, polished, with five or six whorls and a rather acute spire ; nucleus minute, more or less immersed, eroded to some extent in every specimen ; apical whorls smooth, polished, rounded ; suture very distinct, in the majority of cases not channelled ; the apical whorls with two or three distant narrow grooves across which, in some cases, pass elevated lines of growth which appear nowhere else, or, if at all, only in the suture near the apex ; last whorl forming the largest part of the shell, inflated, provided with ten or eleven spiral grooves, which arc nearer together anteriorly ; these grooves are somewhat zigzag by exigencies of growth, but are not punctate, as in so many species ; other spiral sculpture consisting of microscopically fine slightly zigzag striae, about seventy in the width of a millimeter ; transverse sculpture only of most delicate flexuous lines of growth most evident near the sutures ; aperture rounded in front, pointed behind ; outer lip thin, simple, arcuated toward the periphery, passing imperceptibly into the pillar ; body with a slight callus joining the rather slender pillar which carries one inconspicuous fold. Lon. of shell, 9.0; of last whorl, 7.0; of aperture, 5.75. Max. Lit. of shell, 5.75 ; of aperture, 3.0 mm. A peculiarly thin delicate polished and inflated species.
