Leptomaria undetermined

Leptomaria sp. Plate 2: figs 1, 2 Material. 1 specimen, SNSB – BSPG 2016 XXI 1628. Description. Shell broadly trochiform conical with straight sides; specimen 27 mm high; sutures indistinct; ornament of early whorls poorly preserved showing few spiral cords; selenizone visible as broad band in supra-median position on last whorls; whorl face ornamented with spiral cords, 3 above and 4–5 below selenizone; adapical spiral cords weaker than abapical cords; last whorl also ornamented with broad, bulging, prosocline, axial ribs that are poorly demarcated from their interspaces; interspaces between ribs approximately as broad as ribs; intersections of axial ribs and spiral cords usually not nodular or only weakly nodular; only one spiral cord below selenizone has distinct nodes; transition from whorl face to base at rounded edge; base flat, densely covered by spiral cords that are not nodular and broader than their interspaces; aperture not preserved. Remarks. Leptomaria sp. differs from Leptomaria goldfussi (Sieberer, 1907) by having straighter shell sides, being more acute, having broad, bulging, poorly defined axial ribs and by largely lacking nodes at intersections of axial ribs and spiral cords.
