Sinezona

Sinezona is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Scissurellidae, the little slit shells.

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.

Distribution

This marine genus occurs worldwide.
