Pyrgodiscus (‘Kinkerii’) kinkeri Pantocsek 1905: 90 , pl. 34, fig. 486 (Figure 34–5)

TYPE:— DENMARK, Mors (“ In stratis tertiariis ad Mors in insula J ̧ttland [sic]”, Pantocsek 1905: 90; BM 68373–5 !, Tempère & Peragallo, Diatomées du monde entire, 2 nd edn: 16, “ MORS (Jutland) | (Dépôt fossile Marin)”, nos 27–29; the index ( Tables) notes only no. 29 as having Pyrgodiscus kinkeri Tempère & Peragallo, 1915: 54 ), BM Adams L 22! (“ F ̧r Jutland | 2.3.[19]15 | J. A. L.[ong]”).

ILLUSTRATION:— Desikachary et al. (1987: pl. 214, figs 1, 2, Indian Ocean sediments.

It has been suggested that this is a species of Omphalotheca jutlandica (e.g., Homann 1991: 131, taf. 53, figs 1–11 and taf. 53, figs 12–14 [“ Omphalotheca aff. jutlandica ”] and Chambers 1997: 265–6). A specimen from BM Adams L22 (“F̧r Jutland”, Figure 35) partially supports that view, but it is possibly a species of Trunculatus (cf., Truncatulus tortonicus in Suto 2006: figs 128–133).
