Calliostoma tranquebaricum is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae.

It is very pale colored, almost white, minutely tessellated on the ribs with light brown.

The short spire is conic, acute, with its lateral outlines rectilinear.

This species is easily recognized by the low-conical form, the finely sculptured flat whorls, edged at periphery and its sutures by a pair of strong lirae.

[2] This marine species occurs off India, Sri Lanka and Vietnam.
