Other species referable here are P. strigosus (Gould, 1859), P. affinis (A. Adams, 1855) and (Reeve, 1865). P. strigosus from Japan appears to have a far more prominent double columella fold than any of the others; it shows a well-developed parietal denticle, and has the groove separating this from the columella fold markedly reduced; spiral sulci are fewer than in P. daviesi.

P. strigosus from Japan appears to have a far more prominent double columella fold than any of the others; it shows a well-developed parietal denticle, and has the groove separating this from the columella fold markedly reduced; spiral sulci are fewer than in P. daviesi. P. affinis (of which should be regarded as a synonym) is even closer to P. daviesi, differing only in possessing a parietal tubercle and a more strongly bisected columella fold; although generally slightly narrower than P. daviesi, there is some overlap in this respect. P. affinis at the present day lives as far south as Durban Bay (it is the species misidentified by Barnard (1963a: 316) as Solidula sulcata (Gmelin, 1791)). In all probability Pupa daviesi originated as an isolated deme of the P. affinis population, but in view of the structural differences we believe that it should be given full species status. This species has been named in honour of Professor O. Davies, collector of much of the Natal Museum Pleistocene material used in this 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.
