Laevitomaria hierlatzensis (HÖRNES, 1853) (Figure 42) 1853: Pleurotomaria Hierlatzensis HÖRNES — HÖRNES, p. 762. 1861: Pleurotomaria Hierlatzensis H()RN. — STOLICZKA, p. 187, pi. 4, fig. 2. 1937: Pleurotomaria aff. hierlatzensis HÖRNES — PCI IELINCEV, p. 22 , pi. 5: 6. Lectotype — GBa 2008/69/40/1 (selected here). Material — GBa 2008/69/40/1—35 specimens, none of them is undamaged. Measurements H HL HP lectotype *9.5 *8.5 *5 Shape — Small, conical shell with cyrtoconoidal earliest whorls and blunt apex. Whorls feebly convex and separated by slightly canaliculate suture. Selenizone flush, wide (one quarter of distance between nearest sutures) and mnning at midwhorl on juvenile shell but shifting slightly toward periphery on subsequent whorls. Periphery rounded angular and feebly swollen. Base low, flattened and narrowly phaneromphalous (probably cryptomphalous in adult stage). Rim of umbilicus rounded angular. Outer lip not preserved between periphery and suture but collabral ornament suggests it rather prosocline and slighdy prosocyrt above slit. Basal lip strongly prosocyrt except short outer part where opisthocyrt. Parietal lip present as thin inducture, columellar (umbilical) lip considerably thickened and bearing a few (45) spiral threads terminating before outer edge. Sculpture — Whorls and base covered by nearly equally spaced spiral threads, being stronger near upper suture, at and near periphery and around umbilicus. Periodically repeating collabral riblets between selenizone and sutures; lunulae of same periodicity

7 on selenizone. On last whorl, riblets fade out in outermost belt of base. All riblets weaken towards selenizone. Peripheral riblets sometimes interfering with spiral threads thus resulting tubercles. Remarks — Top of convexity

7 of the whorls can be found in the middle of upper half of the whorls on some specimens therefore the shell resembles those of gradate outline. However, no distinct angulation (and ramp) was observed. Therefore this species must be ranged to genus Laevitomaria. Distribution — Hallstatt, Hierlatz Alpe, Upper Sinemurian (Oxynotum Zone).

Laevitomaria danii n. sp. (Figure 43) 1980/ Ij'ptomaria sp. - SZABÓ, p. 60, pi. 3, fig. 5. Holotype — HNHM, M 2008.542.1. (Figure 43: A-C), paratypes: HGM J.08.1

1.1. and J.08.12.1. (Figure 43: D-H). Type locality — Lókút, Fenyveskút (Bakony Mts). Type strata — Upper Pliensbachian massive, red, micritic limestone (atypical Hierlatz Limestone), found on uneven surface and in fissures ot Upper Triassic to lowermost Jurassic platform limestone (Dachstein Limestone and Kardosrét Limestone Formations); the fossils frequendy have Fe—oxide coating. Name — Dedicated to Daniel SZABÓ, the author's younger son, photographer of many images in this monograph. Diagnosis — Conical shell with feebly acute apex (juvenile whorls), consisting of numerous low, convex whorls, separated by impressed-canaliculate suture; selenizone prominently wide; peripher)

7 rounded angular, base feebly convex and rather broadly phaneromphalous; network ornament of fine threads on whorls, only spiral lines on base. Material — Three specimens from three different localities; one of them Late(?) Sinemurian, the others are Late Pliensbachian.
