Description
The size of the shell varies between 10 mm and 20 mm. The globose-conic shell is more or less depressed. It is imperforate or very narrowly perforate. The sculpture is spirally finely striate, the striae becoming obsolete on the body whorl. The sharp incremental striae are microscopic. The apical whorls are white and eroded. The remainder is covered with a regular, elegant, minute reticulation formed by the intersection at right angles of two sets of obliquely descending black or bluish lines. The body whorl is subangulate at the periphery. The thin outer lip is acute, inside green,and beautifully iridescent. The arcuate columella is not dentate and is pearly edged. The umbilico-columellar area is vivid pea-green.
