Creniturbo sp. 1

Plate 5: figs 1–4

Material.

4 specimens from Saal: SNSB – BSPG 2016 XXI 1745 –1748 (2 specimens collection Sylla, 1 specimen collection Keupp, 1 specimen collection Lang).

Description.

The present specimens are moderately to poorly preserved; shape, size and sculpture correspond – as far as can be seen – to those of the Creniturbo gibbosus n. sp.; however, the present specimens have a more or less distinct spiral cord on the base, directly below the basal edge; additional faint spiral cords obscured by poor preservation present on base; nodes on basal angulation much weaker than in Creniturbo gibbosus .

Remarks.

Cerithium binodum Buvignier, 1852 is larger, its base is more convex and it has two rows of nodes on the basal edge. Creniturbo dirce (d’Orbigny) sensu Loriol in Loriol and Koby (1890) is also larger with a double row of nodes on the basal edge and it has strong spiral cords on the base.
