Crossostoma sp. (Plate V: 14) — A single, unpublished specimen is found in STOLICZKA (1861) original collection (NM). The shell morphology is rather simple; most conspicuous element is a widely enlarged, trumpet-shaped outer lip. Its morphology is different from that of the known species. However, further studies are necessary to decide whether the specimen represents a new species or not. Without the peristomal modification, the shell could be identified with Ataphrus latilabrus (STOLICZKA, 1861) because the morphology and the measurements are so similar. Eucyclus (Eucyclus) alpinus STOLICZKA, 1861 (Plate V: 15) — Rather large, high turbiniform shells (GBA, 1 original, and MTM, 3) with convex whorls belong to the species. Suture is deeply canaliculate. The peripher)

7 of the whorls can be found well above the suture. Base is convex and anomphalous. Four, nearly equally spaced, nodosed carinae run between the upper suture and the periphery of whorls. A further but unnodosed carina is exposed above the lower suture. The suture itself runs just on a strong spiral cord. Spiral cords, that are much denser than the carinae of the whorls, cover the base. Eucyclus (Eucyclus) sp. — A single specimen from STOLICZKA (1861) collection (NM) that has smaller but more turriculate shells than E. (E.) alpinus, and the number and arrangement of the spiral ornamental elements are also different. The shell outline is also unlike because it is slightly coeloconical. In this latter character, the specimen resembles E. (E.) harnahasi SZABÓ, 1995 but the whorl cross-section and the spiral ornament indicates belonging to another species, which seems new. Eucyclus (Lokuticyclus) sp. (Plate V: 16-18) — The specimen is low turbiniform, and extremely thin-shelled like the other members of the subgenus. Wmorls are convex, rapidly expanding, and canaliculate suture separates them. Base is convex and moderately phaneromphalous; the margin of the umbilicus is rounded-angular. Peristome does not show outer modification, internally it is not observable, but trace of inner thickening is visible on the inner mould of the last whorl. The ornament consists of sparse, spiral threads on the whorls and dense, weaker threads on the base. Delicate, collabral threads cross them. The specimen is different from the known members of subgenus Lokuticyclus. STOLICZKA (1861) misidentified the only specimen (NM) as "Turbo orion D'ORBIGNY, 1853". However, COSSMANN (1916) and FISCHER & WEBER (1997) revised D'ORBIGNY'S species and they regarded it Metriomphalus (Nododelphinulidae), having marked, spiny ornament. Wilsoniconcha ? aff. bipHcata (M. GEMMELLARO, 1911) (Plate V: 19-20) — A single unpublished specimen (GBA) of pupiform shape and retiform ornament represents this species in the fauna. The network consists of spiral cords and collabral threads with granulae at the crossing points. Peristome is ovate, a narrow (? false) umbilicus is visible at the lower part of the inner lip. Presence of columellar folds cannot be checked owing to the state of preservation. The specimen seems to belong to the same species that has been found in the Bakony Mts (Hungary, SZABÓ 1995) in a stratigraphical level with mixed Late Sinemurian and Early Pliensbachian faunal elements. Both specimens show significant differences from GEMMELLARO'S species description. A comparison between specimens will be necessary

7 to decide about the question of identitity. Cirrus hoernesi (STOLICZKA, 1861) (Plate V: 21-23) — High-turbiniform, hyperstrophically left-handed shells (2, NM) of apparendy truncated apex belong to this species. Four latest whorls are visible that are convex, bicarinate at periphery and a rather deep suture separates them. Strong, sparse costae and marked growth lines give the collabral ornament. Base is slighdy convex, anomphalous and evenly arched, opisthocyrt growth-lines mean the only ornament. The peristome is circular, its inner lip is wide and outward tapering.
