Eunerinea sp. 2

Plate 14: figs 7, 8

Material.

1 specimen and a fragment from Saal, SNSB-BSPG 2016 XXI 1926 –1927.

Description.

Shell high-spired, slender; specimen 39 mm high; sutures inconspicuous; angular edge at transition from whorl face to base exposed somewhat above suture; strong spiral cord situated at a clear distance from adapical suture; whorl face between this spiral cord and adapical suture concave, between this cord and abapical suture straight to slightly concave; edge at transition from whorl face to base very pronounced, slightly protruding, forming whorl periphery; edge probably knobby, which is not entirely certain due to preservation; base moderately convex, details are not preserved.

Remarks.

The similar Ptygmatis nogreti Guirand and Ogérien sensu Loriol in Loriol and Bourgeat (1886–1888) has a strong spiral cord directly below the suture. Ptygmatis carpathica sensu Loriol in Loriol and Bourgeat (1886–1888) is larger, not as slender and the subsutural spiral cord is not broadened.
