Scissurellidae, the little slit shells.
[WoRMS : Sinezona; accessed : 21 October 2010](_blank)
/ref>
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.
