Description

Polinices? sp. B

Figs 25 O–P

2014 Polinices? sp. Hansen & Surlyk: tab. 3.

Material. MGUH 33160, a specimen from the unofficially catalogued sample SR.741.C, and a last specimen without number deposited in the old collections of the Natural History Museum of Denmark.

Occurrence. Lithified top of the Maastrichtian Højerup Member at Rødvig and Holtug Quarry, Stevns Klint.

Description. Protoconch low-spired, on specimen MGUH 33160 2.1 mm wide and about 1.6 mm high, consisting of around 2 ¾ whorls. Whorl height only slowly increasing.

Teleoconch fairly high-spired with relatively weakly convex whorls, separated by deep suture. Whorl height corresponding to half the width, increasing rapidly abapically. Growth lines prosocline, nearly straight.

Remarks. The fragmentary preservation of the specimens prevents a sound generic assignment, but the overall form strongly resembles that of Polinices. It is distinguished from Polinices? sp. A described above by the elongated spire and apparently also by a slightly higher whorl number for the protoconch.
