The size of the shell varies between 28 mm and 51 mm. The smooth shell is ovate, oblong and fusiform. It is, whitish, slightly diaphanous, surrounded by two brown bands, interrupted by very prominent chestnut-colored spots upon the lowest
whorl of the
spire. A band of the same color, but less distinct, exists upon the other whorls. The spire is composed of seven or eight slightly angular whorls, the two or three lowest, crowned with a row of elongated, solid, pointed tubercles, pretty near to each other. The tubercles of the upper whorls are less apparent. The ovate
aperture is yellowish. The base is pretty strongly emarginated. The thin outer
lip is arched, marked internally by two transverse brown bands, which are very apparent externally. ==Distribution==
