Zircia zircensis sp. n. (Plate II: figs. 19-20) Holotypus : Plate II : fig. 19. — Locus typicus : Bakonybél, Somhegy — Stratum typicum : horizontal fissure-filling limestone — Derivatio nominis and diagnosis: see above, at Zircia gen.n. Measurements: H HL HA D W A Plate II: fig. 19 8.2 6 4.5 6.2 60° Material — Seven, mostly damaged specimens, well completing each other. Shape — See in the diagnosis. Ornament — No transversal ornament is besides the fine prosocline growth lines. These are crossed longitudinally by a few lines below the carina, the first of them appears on the fifth whorl and their number increases to three or four at the last whorl. On the base, except a narrow band beside the callus, dense spiral grooving is seen. Embryonal shape and ornament — The subglobose protoconch consists of a smooth nucleus and about 2.5 whorls, which are convex and unsculptured. The appearance of the carina may be the boundary between the embryonal and the juvenile shell. Remarks — The "C'-like callus is circumscribed by a groove, its lower part may be a slit to a possible umbilicus. Distribution — Bakony Mts.
