Description： Yellow form, Alor Island, off East Flores Island,
Indonesia. March 2008.
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.
