Distribution — Bakony Mts, in almost all Upper Pliensbachian (Stokesi Zone) strata; Western Ponticls localities of the Upper Sinemurian (Raricostatum Zone) to (Turkey), Raricostatum to Ibex Zone. Riselloidea noszkyi SZABÓ, 1995 (Figure 78) 1995: Riselloidea noszkyi sp. n. — SZABÓ, p. 71, pi. 7, figs 1—3. M a t c r i a 1 — Three poorly preserved specimens, the holotype (HGM Jl 1464) shows all specific characters. Measurements H HL HP D W AA AL holotype *14 *10 *7 *13 - - 70° Figure 78 — Riselloidea noszkyi SZABÓ, 1995; refiguration of the holotype. — "Apertural" (A, E), dorsal (C, F), basal (D, G) views, B and H images show the largest shell remnants with ornament; A—D = xl, L—

H = x3. Shape — Shell trochiform, rather small. Spire nearly conical, wdiorls and base moderately convex; suture in shallow canal; periphery angular. Base more flattened than whorls and anomphalous. Peristome not preserved. Sculpture — Three spiral cords visible on last and penultimate whorls, fourth one on last whorl periphery, just overlapped by suture on earlier whorls. Collabral ornament consists of periodically repeated riblets of similar strength to that of spiral cords. Riblets strongest near upper suture and gradually weaken towards abapical edge of whorls. Tubercles developed at crossing points of ribs and cords. All these ornamental elements reflected also on inner mould. Denser spiral cords on base, fine collabral threads cross them. Growth lines and other collabral elements prosocline and prosocyrt. Remarks — Riselloidea noszkyi has sparser ornamental elements on the whorls than R. multistriata (BÖCKH, 1874) and collabral elements are much weaker, only cords in the latter species; the measurements are also significantly different. Morphologically and by the stratigraphical occurrence, Riselloidea noszkyi SZABÓ, 1995 may be the ancestor of Riselloidea multistriata (BÖCKH, 1874). Distribution — Úrkút, Csárdahegy, Lower(?) Sinemurian; Sümeg, Mogyorósdomb, Upper (?) Sinemurian (both Bakony Mts). Genus Trypanotrochus Cossmann, 1918 Type species: Trochus normanianus D'ORBIGNY, 1850 Trypanotrochus granuliferus (STOLICZKA, 1861) (Figure 79) 1861: Trochus granuliferus STOL. — STOLICZKA, p. 172, pi. 2, figs 2-4. Lectotype — GBa 2008/69/18/1 (selected here). Material — Five damaged, shelly specimens without protoconch and peristome from the "originals collection" and several specimens from the "background" collection.
