Stimpson collected it in Simon's Bay (False Bay), and I have myself collected large specimens in False Bay up to 30 X 23 mm. One specimen 32 X 27 mm. was obtained by U.G.T. at Saldanha Bay. Macnae & Kalk (1958, p. 127) list 'imperforata' from Inhaca Island (Delagoa Bay); I have not seen the material. A subscalariform aberration, 12 X 8-5 mm., was found by Dr. Muir at Still Bay (fig. 7 c).. Fig. 7. Operculum of: a, Natica saldontiana Bartsch. b, N. marochiensis (Gmelin). c, sub- scalariform freak of N genuana Rve., 12x8-5 mm. d, radula teeth ofPolynices cleistopsila n. sp. e, Falsilunatia pseudopsila n. sp. JV. aureozona may be one of the numerous colour variations of genuana. A specimen agreeing with Tomlin's description and figure but larger: 15X15 mm., from Algoa Bay, 32 fathoms, has a short umbilical chink (cf. Tomlin's fig. 4) as in saldontiana, and was identified by Sowerby as sagraiana. Natica saldontiana Bartsch Fig. 7 a Natica sagraiana D'Orb. var. Sowerby, 1903, p. 229. Natica saldontiana [sic] Bartsch, 1915, p. 140, pi. 13, figs. 1-3. The umbilicus is not completely closed even in adult shells, a small semi- m, mil, i 1 chink remaining, and the columellar callus narrows anteriorly, petering out before reaching the most anterior part of the aperture..
