Family Ataphridae COSSMANN, 1918 Genus LEWISIELLA STOLICZKA. 1868 Lewisiella acicula (HÖRNES, 1853) (Plate I: figs. 4-5) 1853: Trochus aciculus HÖRNES, p. 759. 1861 : Trochus aciculus HÖRN. — STOLICZKA. p. 173, pi. 2. fig. 8. 1876: Turbo aciculus STOL. — TATE. p. 344. pi. 9, fig. 22. Measurements: H HL HA D W A Plate I: figs 4-5. — 10 4.5 10.5 5 46° Material — A single specimen with damaged apex and peristome. Shape — The shell is dextral, conical. The whorls are somewhat convex, their inner space is nearly circular in cross section. The periphery is rounded, the base is convex, with a large depression in the middle. The entirely preserved part of the peristome is the strongly thickened inner lip, to which a lunuliform callus is connected between the parietal part and the foot of columella. This callus fills mostly the basal depression. Ornament — The surface of the whorls and the base is covered by prosocline and orthocline. fine growth lines, respectively. These are intersected by faded spiral grooves. The latter ones are missing from the base. Distribution — Northern Alps: Hierlatz limestone; England. Yorkshire: Pliensbachian; Bakony Mts., Kericser: beds with mixed Obtusum to Ibex Zone faunas. Remarks — This form can be easily identified with help of the cited descriptions and figures.
