Nerinea bruntrutana Thurmann, 1832 sensu Quenstedt (1881-1884)

Plate 19: figs 1, 2

v1881-1884 - Nerinea bruntrutana Thurmann - Quenstedt: 534, pl. 206, fig. 2.

Remarks.

The fragmentary specimen from Nattheim that was assigned to N. bruntrutana by Quenstedt (1881-1884) consists of a single complete whorl and two whorls that are partially preserved. The shell is slender. The whorl face is weakly convex, without visible ornament. The sutures are weakly impressed. The base is not preserved. The aperture is strongly damaged. An umbilicus is present and filled with quartz. A strong and a weak columellar, a strong parietal, and a palatal plait are visible. A safe identification of this specimen is impossible. Nerinea bruntrutana Thurmann (in Thurmann and Étallon 1861-1864) differs significantly in having lower whorls that increase more rapidly in width, a straight whorl face, and weakly impressed suture.
