The thickened shell is shiny, with a purple lilac coloration on the upper whorls, below the yellow protoconch.
The shell is reticulate (quite tight in the upper whorls, more expanded at the body whorl) with a granular, high mesh network produced by the intercrossing of vertical rounded, rather strong ribs and 3 strong decurrent cords.
The outer edge is oblate-convex in the upper part but substantially swollen on the fifth and sixth ribs, which show a white appearance, and protrudes on the aperture.
The aperture is thickened on the last rib, crenelated on the sharp outer lip and furnished inside with 5 denticulate folds.
The subsutural sinus cuts rather deep into the thickening of the outer lip, where it expands and becomes rounded.
