Lewisiella stoliczkai n. sp. (Figure 53) 1861 : Pitonillus conicus D'ORB. — Sri MJCZKA, p. 178, pi. 3, fig. 4. 1911 : Pitonillus conicus D'ORB. — M. GEMMF.I .] ,AR( ), p. 230, pi. 10, figs 7-9. Holotype — GBa 2008/69/28/1. Type locality — Hallstadt, Hierlatz Alpe. Type strata — Sinemurian (Oxvnotum Zone) Hierlatz Limestone. Name — Dedicated to Ferdinand STOLICZKA. Diagnosis — Conical shell with blunt apex and slightly convex whorls; periphery angular, except last quarter whorl; large axial depression on base, surrounded by angulation; extremely heavy callus forms ridge in basal depression and terminates in broad triangular surface accreted to columellar lip. Dense spiral striae visible on whole base (except ridge) and few ones above periphery

. Material — Two strongly recrystallised specimens in the "originals collection", one of them with poorly preserved protoconch; twenty-five specimens in the "background collection". Measurements H HL HP holotype 9.3 6.5 3.8 GBa 2008/69/28/2 - 6 4 Shape — Conical shell with blunt apex, slightly convex whorls and somewhat impressed suture. Peripher}

7 angular on juvenile whorls of both specimens but becoming rounded on last whorl of one specimen. Protoconch subglobular with sphaerical initial chamber and roughly one whorl, after that final mode of coiling onsets. Base convex with shallow central depression, surrounded by angulation at midway between peripher}

, forming ridge that raising from median depression of base. Between ridge and columellar lip, narrow false umbilicus visible; aperture circular. Sculpture — Protoconch seems completely smooth (may be also eroded). Few fine, spiral striae visible on both sides of suture and whole base striated. Growth-lines extremely fine, feebly prosocline on whorls and outer half of base and broken into more prosocline along basal ridge. Remarks — STOLICZKA (1861) identified the same specimens as Pitonellus conicus D'ORBIGNY, 1853, however the characters, collected in the diagnosis above, separate the Hierlatz (and Sicily) finds as independent species from the holotype, presented by FISCHER & WEBER (1997). The same characters, the lack of an umbilicus and the smaller adult size distinguish D W AA AL 8.2 4.2 57° 57° 7.5 4.2 63° 63° Lewisiella stoliczkai n. sp. from Lewisiella} turbinate! n. sp. (see below). Distribution — Hierlatz Alpe, Upper Sinemurian (Oxynotum Zone); Galati (East Sicily), Upper Pliensbachian.

Lewisiella? turbinata n. sp. (Figure 54) 1983: lewisiella aäcula (HÖRNLS, 1853) — SZABÓ, p. 29, pl. 1, figs. 4-5. Holotype —HGM J.08.17.1. Type locality — Lókút, Kericser (Bakony Mts). Type strata— Atypical Hierlatz Limestone with Upper Sinemurian to Lower Pliensbachian mixed fauna. Name — Referring the high turbiniform shape. Diagnosis — Rather high turbiniform—conical shell of convex whorls and impressed suture. Periphery rounded, base convex and having rather deep basal depression. Narrow umbilicus present, surrounded by heavy carina
