Scientific name： Amphidromus inconstans
Description： Alor Island, Island off East Flores. Indonesia. March. 2014.
A relatively small (29-38 mm. high) shell with white or brown apex and with the early whorls quite variable in coloring. The basic inconstans pattern has four spiral brown bands on the last whorl, the upper two of square chestnut-colored spots, the lower two either continuous or also interrupted into spots.
It differs from contrarius in lacking the callus nodule; from laevus in having brown, not orange, bands (when bands are present); and from reflexilabris in having a simple lip.
