Type material: Clathurella producta : lectotype (designated by Kay 1965) BMNH 1962761 . D. mauritiana : holotype BMNH 1893.8 . 18.10, don. G.B. Sowerby. C. foraminata pyrgodea : holotype BMNH 1925.3 .12.5. Regional locality data: SOUTH AFRICA: KwaZulu-Natal: between Kosi Bay and Bhanga Neck, - 13 m, sand (D. Herbert; NMSA S3006 About NMSA ) , same locality, ca - 8 m (D. Herbert & K. Bloem; NMSA S771 About NMSA ) ; off Boteler Point , - 70 m, coral rubble (R. Kilburn et al.; NMSA E5727 About NMSA ) ; Aliwal Shoal, off Umkomaas , - 25– 28 m (D. Herbert; NMSA S9894 About NMSA ) . Eastern Cape: Mzamba , beach drift (J.P. Marais; NMSA A5295 About NMSA ) .

Distribution: Hawaii and Polynesia to Red Sea, Mauritius, Mozambique and eastern South Africa.

Remarks: K. producta belongs to a highly problematic complex of taxa, much confused in the literature. Examination of the relevant types and fresher samples from various localities leads me to propose the synonymy given above. Comparison of types of D. mauritiana ( Fig. 40 View Figs 39–45 ) and C. foraminata var. pyrgodea ( Fig. 41 View Figs 39–45 ) shows them to be conspecific, and Clathurella producta ( Fig. 39 View Figs 39–45 ) to have been based on a slightly worn specimen of the same species. Although D. mauritiana was synonymised with Kermia tessellata ( Hinds, 1843) by Hedley (1922), Powell (1966) and Cernohorsky (1978), the extant types differ as follows: those of D. mauritiana (and C. foraminata pyrgodea ) differ from K. tessellata ( Clavatula tessellata Hinds, 1843: 44 , syntype BMNH 1879.2.26.82 ex Lombe Taylor coll.—presumably not the figured type (Hinds 1844: 23, pl. 7, fig. 11) as it is worn and broken) in their shouldered whorls, finer sculpture, flatter outer lip and strongly contracted base ( Fig. 48 View Figs 46–49 ). Two similar but evidently distinct species are Kermia apicalis (Montrouzier in Souverbie, 1861) and Kermia daedalea (Garrett, 1873) . Of these, the former, according to the holotype of Pleurotoma apicalis in MHNB ( Figs 46, 47 View Figs 46–49 ), has non-shouldered whorls and a less contracted base than K. producta . K. daedalea is discussed below.
