Sinezona
''Sinezona'' is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Scissurellidae, the little slit shells.〔(WoRMS : Sinezona; accessed : 21 October 2010 )〕 ==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''.〔( Suter H.
