Perrona is a genus of sea snails, marine gastropod mollusks in the family Clavatulidae.

Description

In this genus the spire is carinated or smooth. The whorls are not tubercular or spinose. The anal sinus can be found more or less near the suture.

The smooth shell is fusiform. The spire is short with few whorls. The aperture is narrow. The siphonal canal is long. The outer lip shows a wide shallow sinus near the middle. The inner lip has a thick callosity at the hind part near the suture.

The species of Perrona are smooth and solid shells with a notch in the middle of the outer lip. The hind part of the body whorl is gibbous, and the columella, as in that genus, is callous posteriorly.
