Drillia

''Drillia'' is a genus of small sea snails, marine gastropod mollusks in the family Drilliidae.
==General characteristics==
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 body whorl is usually short. The columella has a posterior callus. 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 siphonal canal is short, curved and usually narrow.
The animal has tentacles approaching at their bases and eyes near their extremities.〔George Washington Tryon, Manual of Conchology vol. VI p. 155; 1884〕
