s. The first two (embryonic) are smooth and shiny, the other grated with decurrent spiral striae (5 or 6 on the penultimate whorl and about fifteen on the last) and by well marked growth lines, strongly arched in the middle of the upper striae on top of the last. The aperture is fairly narrow, not reaching half the total height of the shell and terminating at the base in a very short, wide open canal. The columellar edge is arched at the top, then with a plicate projection turning obliquely downward. This edge is provided with an eye-catching and limited callus. The lip is simple, smooth on the inside, deeply indented at the top and prominent in the middle.
