Vanitrochus tragema

(Original description)This is a small conical chalky-white shell, colourless excepting for scattered transverse pink flames round the upper parts of the lower whorls just below the sutures.

The shell contains six whorls six, two being in the protoconch, slantingly angled in a gradate manner.

The surface is closely acutely ribbed, the transverse decussations somewhat noticeable in the interstices, and these in some specimens give a crenulate appearance to the ribs themselves.

The base is spirally costulate, as are the upper whorls.

[3] This marine species occurs off the Loyalty Islands, Tuvalu, and Australia (Queensland)
