Description

The shell has turbinate or depressed turbinate form. The anal fissure is closed, forming a foramen in the outer wall of the aperture. The slit fasciole is shorter, not over 1½ whorls in length.

Sinezona is a Scissurella in which the anal slit becomes closed in the adult, and transformed into an oblong perforation like one of the holes of a Haliotis.[2]

Distribution

This marine genus occurs worldwide.
