Description

The length of the shell attains 8 mm.

(Described as Marginella gracilis) The shape of the slender shell is between fusiform and cylindric. It is white, with three spiral bands of orange brown, of which the upper one appears on the spire, a part of the middle one is seen in the deflection of the suture in the last part of the penultimate whorl. The middle band is sometimes indistinct: smooth and shining. The apex is rather obtuse. The spire is moderately lengthened, with the outlines quite curvilinear. The shell consists of nearly four whorls, moderately convex, with the suture not very distinct. The body whorl is long. The aperture is long and narrow. The outer lip is moderately thickened and slightly incurved. The varix is slightly extended on the penultimate whorl. The columella shows four very oblique plaits. [2]

Distribution

This marine species occurs off Jamaica, Caribbean Sea and off Brazil in the Atlantic Ocean.
