served; three spiral threads appear on second one. Granules are sitting at crossing points of riblets and threads. With weakening of riblets, additional spiral threads develop below periphery of whorls, and then fine lines appear also on "ramp". Spiral threads cover also base. Remarks — Doubtlessly, this species is rather similar to Anoptychia turgida (STOLICZKA, 1861), but the measurements, first of all the wider spiral angle, and the details of the ornament distinguish them. Their close phylogenetic relation is very likely. Distribution — Schafberg over St. Wolfgang, (Austria), Late Pliensbachian. Anoptychia turgida (STOLICZKA, 1861) (Figure 87: C-I) 1861: Chemnitina turgida STOL. — STOLICZKA, p. 165, pi. 1, fig. 5. 1983: Anoptychia turgida (STOLICZKA, 1861) — SZABÓ, p. 32, pi. 2, fig. 4. Lectotype — GBa 2008/69/5/1 (monotype). Material — Single specimen in the "originals collection" (GBa), two specimens from Sümeg (Bakony Mts) (HGM). Measurements H lectotype HL *9 HP *6 D 7.5 \\ 4 AA AL 22° Shape — Moderately turriculate shell with convex whorls, last one turns without angulation into similarly convex, anomphalous base. Suture rather deeply impressed. Last whorl feebly deviates abapically, probably indicating adult stage. Aperture subcircular, peristome seems simple. Sculpt Li r e — Abapical half of whorls and whole base sculptured by spiral lines. Collabral ornament consists of fine, slighdy opisthocyrt growth lines, and tiny riblets on middle of juvenile whorls. Riblets more regularly repeated and more distinct on earlier shell parts, where they also bear tiny granulae at intersections with spiral lines. Strongest granulae sitting on spiral thread little below midwhorl. Remarks — The only Hierlatz Alpe specimen is rather poorly preserved, only small spots of the ornament visible, but they well correlate with STOLICZKA's (1861) figures. Marked variety of this ornament was found on two Bakony Mts specimens (SZABÓ 1983) that have also the shape of Anoptychia turgida (see Figure 87: C-I). Distribution — Hallstatt, Hierlatz Alpe, Late Sinemurian (Oxynotum Zone); Bakony Mts (Sümeg), Late(?) Sinemurian. Figure 87 — Anoptychia crenata (STOLICZKA, 1861), lectotype (A-B), and Anoptychia turgida (STOLICZKA, 1861), lectotype (C-F) and an additional specimen from the Sümeg (Bakony Mts) Sinemurian (G—I). — 8 a-c: copy of the original figures of "Chemnit^ia crenata" from STOLICZKA (1861) Tafel I; A: lateral view of the lectotype of Anoptychia crenata, xl; B: magnified lateral view to show the ornament of Anoptychia crenata, x3; 5 a-b: copy of the original figures of "Cbemnityia turgida" from STOLICZKA (1861) Tafel I; C—D: oblique "apertural" (C) and dorsal (D) views of the lectotype of Anoptychia turgida, xl; E-F: magnified images to show details of the ornament of the lectotype of Anoptychia turgida, E — x4, F = x7; G—I: another specimen of Anoptychia turgida from the Bakony Mts (Sümeg) Sinemurian (refiguration of specimen published by SZABÓ 1983), having much better preserved ornament than the lectotype, G = xl, H = x4, I = x7.
