1 +The shell is broadly oval. The whorl grows faster in width than in height. The last whorl is very broad and it makes the whole shell outline slightly concave. The whorls of the spire are convex and the last whorl is inflated. There is a narrow ramp in the adapicalmost part of the whorls, with some angulation in the early whorls and a gradual change into the lateral flank in the last whorl. The shell is smooth apart from almost orthocline growth lines. The base is strongly convex, with a very small umbilical chink. The aperture is broadly oval.\\
