Shell long, slender, shining with the lustre of barley-sugar candy; whorls twelve, of which two are nuclear ; nucleus white, smooth, rather large, inflated, polished, not sculptured except by lines of growth, changing suddenly into the normal sculpture ; sculpture consisting of small pointed nodules set on the periphery of the whorls, a little in advance of midway between the sutures, ten to fourteen on each whorl, except the last half-whorl in the adult, where they begin to be obsolete ; the tips of these nodules and a line just in advance of the suture are white as compared with the general translucent pinkish or fleshy hue ; these nodules are a little compressed in the latter whorls in a direction transverse to the whorls ; the lines of growth are distinct and in the later whorls occasionally a little prominent at the suture, against which the shell is appressed ; other transverse sculpture none; revolving sculpture comprised in fifteen or twenty threads on the last whorl, faintly visible at the periphery and gradually becoming stronger toward the end of the canal ; an occasional trace of such might be visible on some of the older whorls ; notch moderately deep ; notch-band not strongly marked ; outer lip in the adult produced (but imperfect in our specimens), apparently having the usual form ; pillar obliquely cut off anteriorly, covered with alight callus ; canal narrow ; aperture short and seemingly rather wide, behind. Lon. of shell, 15.0 mm; of last whorl, 5.75 mm; of aperture, 4,0 mm. Max. lat, of shell, 3.25 mm ; of aperture, about 1.5 mm, Defl, about 16°.
