''Perrona perron'' is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae. ==Description== The shell grows to a length of 25 mm. The pale yellow, fusiform shell is turreted and rather smooth. The whorls are flat, with flexuous longitudinal lines, slightly angulated round the upper part. The lower portion of the last whorl is contracted and has several regular, distant revolving ridges. The anal sinus is nearly central. 〔 George Washington Tryon, Manual of Conchology vol.
