Perrinia is a genus of sea snails, marine gastropod mollusks in the family Chilodontaidae.

[1] This genus has a long time been regarded as a subgenus of Turcica H. & A. Adams, 1854.

[2] The imperforate shell is small (less than 20 mm) and has a trochiform shape.

The whorls are flattened and cancellated with a strongly indented suture.

The outer lip is lirate (= with fine linear elevations) within.
