82 SZABÓ, J.: Revision of Hie: latter species. In its lower spired shell, Eucyclus (Eokutigclus) lokutensis is somewhat likely, but the outline, higher whorls, and fewer spiral cords between the sutures distinguish it. STOLICZKA (1861) misidentified the rare Schafberg specimens as "Turbo orion D'ORBIGNY, 1853". COSSMANN 1916) then FISCHER & WEBER (1997) revised D'ORBIGNY's latz I imestone gastropods species and they regarded it as member of Metriomphalus (Nododelphinulidae) because of its marked, spiny ornament, which is strongly different from that of the specimen, available in STOLICZKA (1861) collection. Distribution — Schafberg over St. Wolfgang, (Salzkammergut, Austria), Late Pliensbachian. Genus Riselloidea COSSMANN, 1909 Type species: Risellopsis subdisjuncta COSSMANN, 1908 Riselloidea multistriata (BÖCKH, 1874) (Figure 77) 1874: Turbo multistriatus n. sp. — BÖCKH, p. 110, pi. 4, fig. 5. 1982: Riselloidea multistriata (BöCkl l, 1874) — SZABÓ, p. 25, pi. 3, figs. 3-6. 1991: Riselloidea cfr. multistriata (BÖCKH, 1874) — CONTI & MoNARl, p. 272, pi. 8, fig. 14. Material — Sixteen, mainly inner mould specimens, some with shell remnants (HGM). Measurements H HL HP D W AA AL Figure 77: A-E - *13.5 *8.5 *16 *9 Figure 77 — Riselloidea multistriata (BÖCKH, 1874); copy figures from SZABÓ (1982). — A-B: dorsal (A) and basal (B) views, xl; C—E: magnified views of the specimen in A—B, to display the details of the sculpture, C—D = X2, E = ornament of the ramp, x6; F: different configuration of the spiral cords on a stratigraphically older specimen, X2. Shape — Turbiniform species with convex whorls and rounded-angular peripher)-. Peristome prosocline with somewhat thickened columellar lip, separated from moderately convex base by pseudoumbilicus. Aperture rounded but with angulations at foot of columella and at suture. Sculpture — Spiral carinae ornament whorls and base. Strongest three of them situated just at periphery and immediately beside it. Lowermost one of these just overlapped by suture of subsequent whorl. AH other (weaker) carinae similar to each other in strength. Pairs of cords separated from each other by interspaces, being wider and different on whorls but narrower and equal on base. Collabral ornament consists of weak collabral cords, being denser than spiral ones and usually running from suture to suture (or to inner lip). Some cords do not reach upper suture but disappear near to it. In such cases, short riblets appear at suture beside earlier ones. Ends of riblets and related cords do not meet. Nodules or tabercles sitting at crossing points of differendy oriented cords. Growth-lines strongly prosocline and, somewhat opisthocyrt on base. Remarks — Riselloidea multistriata (BÖCKH, 1974) was the only gastropod species described before the 1980's years from the Bakony Mts Jurassic. The holotype in the Hungarian Geological Institute Museum is just like the available specimens in shape and ornament, but the depiction given by BÖCKH is somewhat incorrect, since the peripherial carinae follow each other with wider interspaces in reality than on the figure.
