Shell polished, waxy white, seven or eight whorled ; nucleus disproportionately large, smooth at first, shining, very obtuse, white ; second whorl with about fifteen rather sharp transverse ridges parallel with the axis, and not flexuous ; these pass gradually into slightly oblique, rounded riblets, which begin in front of the notch-band with a slight shoulder, then continue across the whorl, and are somewhat attenuated by the time they reach the suture ; of these there are about fifteen on the last whorl, less distinct anteriorly ; the lines of growth are tolerably prominent, and especially so on the last whorl. Of revolving sculpture there is little or none; a few microscopic revolving striae are perceptible in some places, especially on the surface of the rather broad notch-band ; the suture is appressed ; the shouldering of the riblets gives the upper whorls a rather inflated appearance ; the aperture is short and wide ; the notch deep, with its edges turned up and a little twisted ; the canal short, wide, slightly reflected, showing on the pillar a distinct fasciole ; pillar straight, with a distinct callus upon it and also upon the body-whorl; outer lip thin-edged, produced and rounded. Long. of shell, 13.5 mm; of last whorl, 9.5 mm; of aperture, 5.0. mm; Max. lat. 5.0 mm; lat. of aperture, 2.0 mm.
