See text Drillia is a genus of small sea snails, marine gastropod mollusks in the family Drilliidae.

[1][2] The shell is turriculated, with an elevated spire, longitudinal ribs, and usually revolving striae.

The spiral sculpture of the shell is rather smooth or shows a wide spacing of incised lines.

The outer lip is thick, but not varicose, nor dentate within, flexuous, with a well-marked posterior anal sinus near (but not reaching) the suture, and an anterior constriction or sinuosity.

The animal has tentacles approaching at their bases and eyes near their extremities.
