Vaceuchelus ampullus

Vaceuchelus ampullus is a species of sea snail, a marine gastropod mollusc in the family Chilodontaidae.

Description
(Original description)The shell is globose-conic, imperforate in the young, narrowly umbilicated or reduced to a fissure in the adult. It is whitish, spotted with red on the revolving ribs. The whorls of the spire are quadrate, separated by a linear suture. The body whorl is convex, except a little flattening at the suture.

The sculpture of the penultimate whorl consists of three equally thick, obtuse, and plain cinguli (= colored bands or spiral ornamentation), separated from one another and from the sutures by nearly equal interspaces, with or without a small riblet in each interval. All over regularly clathrate, the interstitial pits are narrowly oblong. The body whorl contains about eight cinguli, clathrate in the intervals: the supra-peripheral intervals show a riblet. The four basal cinguli are granulose.

The aperture is roundly oval. The outer and basal margins are smooth within. The columella is arcuate, slightly explanulate concave and edentulous.

Distribution
This marine species is endemic to Australia (New South Wales, Queensland, South Australia, Tasmania, Victoria, Western Australia).
