Figure 43 — Laevitomaria danii n. sp. — A-C: holotype (Fenyveskút) in dorsal (A) and "apertural" (B) views, xl, and magnified dorsal view (C) to show the ornament, x3; D—E: paratype (HGM J.

08.11.1., Eplény) back view (the outline is truncated by a fracture on the left side!), xl (D) and x3 (E); F-H: a specimen from Sümeg (HGM J.

08.12.1.), mentioned in the synonymy, that seems to be an early representative of Laevitomaria danii n. sp., lateral views, xl (F-G), and x3 (H). Measurements H HL HP holotype *20 *8.5 *6 HGMJ.08.11.L HGMJ.08.12.1. *10 *6 Shape — Moderately high conical shell, built of numerous low whorls. Surface of whorls slightly convex, whorl-section tetragonal with rounded angles. Conspicuously wide selenizone (~quarter of distance between sutures) in midwhorl position. Peripher}' rounded angular, base slighdy convex and moderately phaneromphalous; peristome poorly known; basal lip partially preserved in paratype, showing remnants of considerable external varix. Sculpture — Whorls, as well as base covered by spiral threads, crossed by weaker collabral threads, resulting in network, and very fine growth-lines. Collabral elements of network appear as riblets on juvenile whorls. Fine granules may also appear on intersections of differently oriented threads on whorls, mainly in both nearsuture belts of whorls. Growth-lines run strongly prosocline-prosocyrt above selenizone, opisthocline between D W AA AL *16 **6 56° 48° 58° **18 - *53° *46° selenizone and lower suture/periphery, and strongly opisthocline-feebly opisthocyrt on base. Remarks — The specimens best fit to the Laevitomaria genus concept, in which L. hierlatzensis (HÖRNES, 1853) has similar shape and ornament. However, Laerntomaria danii n. sp. has much lower, less rapidly expanding whorls and, consequently, bigger whorl number at same shell height (lectotype of L. hierlatzensis has 7, L, danii n. sp. has more than 8 whorls at same height). L. hierlatzensis has cyrtoconoidal apex, but early shell of L. danii n. sp. is acute; furthermore, differently from Laevitomaria danii n. sp., L. hierlatzensis has a narrow subsutural shoulder, and many other details are different (see Figures 42, and 43). Distribution — Bakony Mts: Sümeg, Late(?) Sinemurian; Eplény, Mn-ore mine and Lókút, Fenyveskút, both Domerian (Late Pliensbachian). Genus Leptomaria E.
