Perrona spirata is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.

[1][2] The size of an adult shell varies between 20 and 30 millimetres (0.79 and 1.18 in).

The whorls are constricted around the upper part, with a rather sharp ridge next to the suture, and an obtuse angle below the constriction.

The color of the shell is yellowish, mottled and striped with chestnut.
