Bullia tranquebarica, common name the lined bullia, is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the Nassa mud snails or dog whelks.

It is of a bright, transparent ash color, covered with longitudinal waved and reddish lines.

They are marked at their upper part by a marginated suture, and two slightly apparent striae towards the base.

The body whorl is shorter than the spire, marked at its base with regular, transverse striae or ridges.

The columella, slightly arcuated, is terminated by a pretty prominent oblique fold.
