Cocculina View in CoL ? sp.

Figs 19 View FIGURE 19 F–G

Material. MGUH 33081, a fragmentary mould of outer surface.

Occurrence. Bay at Boesdal at Stevns Klint, where it was collected from the lower Danian Cerithium Limestone Member of the Rødvig Formation.

Description. Protoconch narrow, smooth, not immersed in posterior slope of teleoconch. Teleoconch short ovate in outline, fairly high with nearly straight to slightly concave posterior slope and gently convex anterior slope; lateral flanks nearly straight. No sculpture except for some faint growth lines.

Measurements. Height of shell approximately 3.3 mm, width at least 5.3 mm.

Remarks. This species closely resembles Cocculina s.l. sp. sensu Kiel (2006) from the Albian of Madagascar with its smooth shell, but may differ in having a relatively higher and less elongated shell with a slightly smoother surface. From all other species of Cocculina it differs in its smooth protoconch and teleoconch, though specimens with nearly smooth shell belonging to the Miocene Cocculina dittmeri ( Anderson, 1964) from Northern to Central Europe have been observed (see Janssen 1984).
