Shape — Rather simple shell morphology, poor in characters, disregarding widely enlarged, trumpet-shaped outer lip, being really conspicuous element. Adapical edge of extended peristome reaches middle of penultimate whorl. Basal depression may be connected to narrow umbilicus; cross-section of apical part support this possibility 7 . No trace of inner constriction found. Sculpture — Delicate, prosocline growth-lines, crossed by dense, obscure spiral lineation, observable only in peripheral region of available specimen by strong magnification. Remarks — C. refkxilabrum D'ORBIGNY, 1853 is contemporary but having much lower spire and a peristome constriction. C. macrostoma (STOLICZKA, 1861) has low spire, smaller adult size and smaller peristome extension. The Bajocian C. expansum CONTI & FISCHER, 1984 is more similar in form but its outer lip extension is smaller. The question mark in the genus name indicate the doubt because of the inferable umbilicus. Presence of an umbilicus may indicate belonging to Paiaeocollonia. Without the peristome modification, the shell could be identified with Ataphrus latilabrus (STOLICZKA, 1861) because the morphology and the measurements are so similar. Distribution — Schafberg at St. Wolfgang (Austria); Upper Pliensbachian. Superfamily Trochoidea RAFINESQUE, 1815 Family Trochidae RAFINESQUE, 1815 Subfamily Proconulinae COX, 1960 Genus Anticonulus COSSMANN, 1918 Type species: Trochus mariae D'ORBIGNY, 1853 Anticonulus lautus (STOLICZKA, 1861) (Figure 57) 1861: Trochus lautus STOL. — STOLICZKA, p. 169, pl. 1, fig. 14. 2003: Anticonulus lautus (STOLICZKA, 1861) — SZABÓ in VÖRÖS et. al., p. 61, pl. 5: 8-10. Lectotype — (monotype, de facto holotype) NhM 1856/0047/0168 (selected here). Material — Single, damaged specimen that belongs to STOLICZKA (1861) original collection part in the NhM. Measurements H HL HP D W AA AL NhM 1856/0047/0168 **10.5 *3.7 *1.9 *6.9 *2.9 *43° 41° Figure 57 — Anticonulus lautus (STOLICZKA, 1861), lectotype. — 14 a-c: copy of the original figures from STOLICZKA (1861) Tafel 1; A-C: two lateral views (A-B) and basal view (B) xl; D: magnificaüon of the best preserved shell part to show the ornament, x3. Shape — Small, fragmentary 7 , conical shell, consisting of numerous (10—12) IOAV whorls of flat outer surface. Whorls feebly swollen along upper suture and bear distinct single spiral thread on lower edge. Flush suture, appearing as marked incision; periphery sharply angular. Base feebly convex and rather broadly phaneromphalous. Neither peristome nor protoconch part found preserved. Interior of whorl cross-section axially flattened ovate. Sculpture — Obscure spiral lines visible on whorls and base beside distinct growth-lines, being strongly prosocline on whorls and opisthocyrt on base. Remarks — The only specimen (indicated also by STOLICZKA 1861) could be regarded as holotype. The species is well distinguishable from the other species of the studied faunas. Anticonulus acutus n. sp. is the only surely congeneric species that has neither subsutural swelling, nor suprasutural thread like Anticonulus lautus. Besides, it has a markedly trochiform shell (acute early whorls, cyrtoconoidal intermediate and coeloconoidal last two whorls) while the shape of Anticonulus lautus (STOLICZKA, 1861) is almost a simple cone, having only feebly trochiform outline. Distribution — Schafberg over St. Wolfgang, around boundary of Salzkammergut and Salzburg Regions, Austria; Upper Pliensbachian. Anticonulus acutus n. sp.
