Japonia Gould, 1859


Genus Japonia Gould, 1859 

Type species: Cyclostoma barbata Gould, 1859  ( Gould 1859: Proceedings of Boston Society of Natural History, 6, p 425)

The genus was characterized by the thin paucispiral operculum with thinned edges, the globose conic form, free umbilicus, nearly circular peristome which barely touches the preceding whorl, and the projecting lamellar striae of growth decussating with revolving ridges in some cares furnished with epidermal barbs ( Gould 1859).
