Perrinia
''Perrinia'' is a genus of sea snails, marine gastropod mollusks in the family Chilodontidae. This genus has a long time been regarded as a subgenus of ''Turcica'' H. & A. Adams, 1854. Previously it was considered a (problematic) subgenus of ''Euchelus'' Philippi, 1847.〔 ==Description== The imperforate shell is small (less thgan 20 mm) and has a trochiform shape. The whorls are flattened and cancellated with a strongly indented suture. The aperture is quadrangular. The outer lip is lirate (= with fine linear elevations) within. The columella is short, nearly straight, with several tubercles near the base.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia )〕
