New Zealand Cenozoic Mollusca

Haliotis (Sulculus) powelli Fleming, 1952


(Pl. 47c): holotype, GS3893, W15/f7501, Ohope Beach, Whakatane, Castlecliffian (TM4908, GNS)

Beu & Maxwell (1990): Chapter 16; p. 347; pl. 47 c.

Synonymy: Haliotis powelli Fleming 1952, p. 231

Classification: Haliotidae

Description: Small for genus (47 mm long), very weakly inflated, with clearly spiral, very low apex but extremely large, depressed last whorl and very large aperture, passing its exhalent current out 4 tremata near the columellar lip; formerly open tremata form a spiral row of low nodes. Sculpture of 20 prominent, narrow, rounded spiral costae, each interspace with several finer costellae, all crossed by irregular, weak to prominent growth ridges.

Comparison: Haliotis flemingi is much flatter and more prominently sculptured than the Haweran to Recent species H. (Sulculus) australis and H. (Sulculus) virginea; and much smaller, flatter, more coarsely sculptured, and with a narrower columellar lip than the well-known "paua", H. (Paua) iris (Opoitian-Recent).

Distribution: Castlecliffian, Ohope Beach, Whakatane (type), not uncommon; ? Nukumaruan, Pohangina Valley, eastern Wanganui basin (Carter 1972, fig. 22, p. 316). A rare fossil, known with certainty only from Ohope Beach but representative of a reasonably good fossil history of Eocene-Pleistocene Haliotis in New Zealand (most records unpublished; see also Haliotis n. sp., Pl. 13g, k; Lee et al. 1983, fig. 2, 3, p. 124).
