The earlier whorls appear whitish, transitioning to yellow on the lower whorls, which are ornamented with two spiral bands of squarish brown spots. Below these, on the body whorl, lie two narrow, dark-brown bands, the upper situated just below the periphery and the lower approximately 2mm beneath the upper. The columella is white, erect, and rounded. The outer lip appears white, slightly expanded, and depressed at the basal portion where it joins the columella. The parietal callus is quite thin and transparent.
