Description (Described in Latin as Cylindrella cumingii) The shell is large and white, and has a slightly fusiform outline; it is very long and heterostrophic (the early and later whorls coil in opposite directions). It is richly ornamented with very numerous, very small, oblique, regular, rounded ribs. The apex is broadly decollate, with whorls 10 or 11 whorls; the remaining upper whorls are very strongly convex, and in total about 8 or 9 whorls persist below the decollation.
The aperture is elliptical and markedly constricted deep within the throat, but it expands outward into a very broad, sharp outer lip. The body whorl is provided with a semi‑revolving keel that helps to form a somewhat effuse aperture.
Distribution This snail occurs on Jamaica.
