Radula teeth of: a, Crepidula porcellana Lam. b, C. aculeata (Gmelin). c, Calyptraea chinensis (Linn.), d, 67. aurita Rve. e, Capulus intortus Lam. Distribution. Europe, Mediterranean, west coast of Africa to Angola. Remarks. Smooth and prickly examples may occur in the same locality, those from Buffels Bay, and from Cape Infanta. There seems no reason to bring solida into the fauna list; von Martens's specimen was certainly only an unusually thick-shelled chinensis. Tomlin described capensis from beach-worn examples, and consequently all the characters which he adduced to separate the Cape shells from chinensis are useless. The colour, as Turton pointed out, is not always purplish; in fact a purple tint is due to some chemical action, and affects other beach-rolled shells ( Charonia pustulata, Conus 'lavendulus'). The altitude is by no means higher than in chinensis: Tomlin gave diam. 18, alt. 6 mm.; I have seen British examples with same altitude, but only 11 mm. in diameter. The internal process Septum) was said to reach the edge of the shell in capensis, but that is clearly because the original margin of the shell had been worn away. Powell's figure (1951, p. 126, fig. E(i)) shows only the septum, not'the reflexed columella Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
