c Shape — Naticiform shell of thin wall and rather protruding spire; protoconch lacking, but first preserved whorl indicates its flattened shape. Whorls convex and rapidly expanding, deeply impressed-canaliculate suture separate them. Peripher)' rounded, evenly arched but slightly flattened adaxially near peristome. Aperture and whorl cross-section axially ovate. Peristome damaged, but its tangential position and discontinuous nature well visible; only thin parietal callosity inferable between suture and axial region of base. Columellar lip rather long and almost vertical. Base strongly convex and anomphalous. Sculpture — Shell smooth, only unequally thin, strongly prosocline growth-lines observable on its surface. Remarks — The shape and the ornament of this species is rather clearly different from those of Neritopsis that has a continuous peristome, thick shell and never smooth shell (disregarding protoconch). This is the only naticoidean shell, found in the Hierlatz Limestone so far. Distribution — Hallstatt, Hierlatz Alpe, Upper Sinemurian (Oxynotum Zone).
