A specimen of drilled "Nerita" sp. The subgeneric placement of the species of "Nerita" was revised by Vermeij in 1984. "Lambis truncata sebae" has a much larger shell than the Nerita species. "Neonympha nerita" (Capronnier, 1881) is a synonym of "Paryphthimoides poltys". The shell assemblage was dominated by "Nerita undata" and "Nerita plicata". In contrast, sunset clams ("Asaphis violascens") and nerites ("Nerita undata") are usually processed residentially. "Theodoxus fluviatilis" was originally described under the name "Nerita fluviatilis" by Carl Linnaeus in 1758. Interiorly when the lip has teeth it is "dentate" as in "Nerita". "Nerita orbignyana" and "Nerita sanguinolenta" are two species of common name "nerite". The closely related species "Nerita melanotragus" occurs in eastern Victoria, New South Wales and Tasmania.
