"shell cylindrical-conical, yellowish to light-brown. First whorl smooth, subsequent ones ornamented with distantly placed fine ribs. These ribs are white or of the same colour as the rest of the shell, standing out wing-like away from the shell. Between the ribs there is a fine spiral sculpture. Shell not shining or transparent. Whorls 6, convex. The first two placed obliquely on the rest of the shell. These first whorls are lying almost in one plane, so that the top of the shell is very obtuse. the following whorls, especially the nos. 5 and 6 are bout equally broad. Hence the profile of this part of the shell is nearly cylindrical. last whorl irregular, constricted transversely in its middle, then widening again towards the trumpet-shaped aperture. The distal part of the ultimate whorl is turned upward along the spire and adnate to it. The free edge of the peristome reaches somewhat above the top of the shell. Aperture facing back, thus giving a false suggestion of a sinistral shell. Suture deep. umbilicus open, narrow, in some specimens hidden by the deviating part of the last whorl. aperture round, oblique. Peristome continuous, circular, with a wing-like collar behind the peristome and parallel to it. Operculum unknown."
