-like appearance, covered by pale strawcolored, filmy periostracum, which occasionally bears weak axial lamellae near labral margin. Protoconch missing in all specimens examined due to corrosion. Teleoconch consisting of at least four roundly inflated whorls with moderately constricted suture. Initial teleoconch whorls with sharp angulation at shoulder, which becomes indistinct on lower whorls. Last whorl large, occupying 89% of shell length. Surface sculptured by fine, crowded spiral cords with narrower interspaces all over. Spiral cords rather uniform in thickness and crowded in basal part of last whorl, but becoming stronger and more irregular adapically, especially on sutural ramp area, where strongest spiral cord sometimes forms weak shoulder keel. 15 or more cords on penultimate whorl, some 40–50 on last whorl. Umbilicus narrow but deep, encircled by indistinct fasciole; inner wall ornamented by weak spiral cords. Aperture semi-circular, entire with no anterior sinus or anal notch. Outer lip smooth, neither reflected nor thickened. Inner lip weakly calloused, continuing to nearly straight columellar lip and barely reflected over umbilicus.

). One probably immature female specimen was examined. Head with relatively large and extremely broad snout and rather blunt cephalic tentacles, lacking pigmented eyes; foot small with propodium and metapodium, separated by narrow lateral groove. Mantle edge simple with small but distinct notch at left corner and simple (not annulate) pallial tentacle in notch in front of anus. Ctenidium well developed, covering nearly one third of pallial roof, and consisting of triangular leaflets. Osphradium relatively small, leaf-like and situated near left corner of pallial roof. Posterior esophagus swollen with soil-like contents, seen through epithelium of mantle floor. Stomach large, comprising large part of ventral side of visceral mass. Rectum also considerably packed with soil-like contents, and sharing most part of right side of pallial roof, especially in its proximal part, leaving little space for gonoduct.

Because of the absence of live-collected specimens of the latter form, both are provisionally regarded herein as forms or growth stages of a single species.

A. holotype. B-D. aberrant specimens from the type locality obtained together with the holotype, NSMT-Mo 78945. All at the same scale. Scale = 1 mm. Anomalous relative shell length (L2) and width (W2) were measured as shown in A to compare the proportions of these specimens (Figure 6) because of the incomplete conditions of the apical part and outer lip of some specimens. L2 represents the length between the apical margin of the penultimate whorl and the intersection of the basal part of body whorl and aperture in the frontal view.
