Gastropoda -
Taxonomy
Naticopsis was named by M'Coy (1844) [Sepkoski's age data: S Wenl-l Tr Carn Sepkoski's reference number: 797]. It is not extant. Its type is Naticopsis phillipsi. It is the type genus of Naticopsinae, Naticopsoidea.
It was reranked as Diaphorostoma (Naticopsis) by Clarke (1904).
It was assigned to Diaphorostoma by Clarke (1904); to Neritidae by Knight (1933); to Archaeogastropoda by Sepkoski (2002); to Naticopsinae by Knight et al. (1960), Frýda (2000) and Bouchet et al. (2005); and to Naticopsidae by Bandel (2007), Kaim et al. (2014), Mazaev (2015) and Nützel and Ketwetsuriya (2016).

| J. B. Knight 1933 | Neritiform to naticiform gastropods with relatively low spire, a thick shell, and anomphalous base; volutions rapidly increasing in size, the body whorl forming most of the shell; plane of the aperture markedly oblique; outer lip thin; columellar lip strongly arcuate, thickened and sometimes with an obscure groove within; parietal inductura strongly thickened and sometimes flattened in the plane of the aperture, often bearing transverse rugae; a narrow channel at the juncture of the outer lip with the parietal wall, probably excurrent; often without ornamentation but with a tendency to fine, transverse lirae which in turn show a marked tendency to fasciculation into costae near the sutures; color markings commonly either zigzag transverse stripes, revolving bands or both combined, often preserved. There is no nacreous layer, but the outermost shell layer, probably calcitic in life, is very resistant to alteration; inner whorls not resorbed; nucleus low, simple and dextral. The operculum is calcareous, moderately thick, oval or subcircular, with growth lines concentric on an excentric, but not marginal nucleus; inner surface with subreniform raised area. |
