Pictavia undetermined

Pictavia? sp. Plate 8: figs 10, 11 Material. 1 specimen, SNSB-BSPG 2016 XXI 1790. Description. Shell naticiform, egg-shaped, significantly higher than wide, 20 mm high; spire small; whorl face convex; sutures distinctly deepened; last whorl very large, inflated, higher than wide but distinctly elevated; transition from whorl face to strongly convex base evenly convex; shell smooth; growth lines not visible; aperture not preserved or covered with rock. Remarks. Natica amata d’Orbigny sensu Loriol in Loriol and Bourgeat (1886–1888) is larger and has higher spire whorls; its last whorl is higher than wide.
