Katosira? hierlatzensis (STOLICZKA, 1861) (Figure 86) 1861: Chemniteça Hierlatzensis STOL. — STOLICZKA, p. 164, pl. 1, figs 3 a-b. v. 1911: Zygopleura? dubia n. sp. — M. Gemmellaro, p. 237, pi. 9, fig. 19. Lectotype — GBa 2008/69/3/1 (monotype). Material — A five whorls fragment of a single specimen is saved in the "originals collection". Measurements H lectotype HL HP D **5. Shape — Holotype indicative of high turriculate shell with slightly convex whorls and impressed suture, but neither earliest whorls nor terminal parts of shell found preserved. Low, swollen belt and shallow spiral concavity

7 below it follow suture abapically. Weaker spiral swollening and concave belt above it observable supra-suturallv. This latter swollening probably abaxial part of that carina, running on angulation separating base and (last) whorl of Katosira and usually overlapped by suture. No trace of umbilicus found. Sculpt Li r e — Feebly opisthocyrt, dense, collabral costellae cover all whorls. In crossing points with sub-sutural spiral swelling, tubercles formed. No tubercles developed on lower spiral swelling. Two other obscure spiral threads cross riblets, one at top of convexity of whorls and another halfway towards lower suture. On last preserved whorl, nodulae seem to appear also at crossings with these latter two spiral elements. Growth-threads also riblet like sometimes, mainly in interspaces of costellae. Remarks — The species Zygopleura? dubia M. GEALMELLARO, 1911 is most probably identical with Katosira? hierlatzensis (STOLICZKA, T861). However, from the latest whorl of the Sicily specimen, which is also incomplete, the marked ornament of the earliest whorls vanished. This changing may indicate belonging to Anoptychia. The shape and the ornament are indicative of a species, distinguishable from the other contemporaneous, similar forms. However, the generic accomodation remains uncertain, because of the lacking shell parts (e.g. the shell may be the juvenile part of an Anoptychia species). Further material and studies are necessary to find confirmed generic name. Distribution — Hierlatz Alpe, Upper Sinemurian (Oxynotum Zone); Galati (Rocche Rosse), East Sicily, Upper Pliensbachian.

V: 26-27. Lectotype — NhM 1861/0034/0008 (monotype). Material — Single, rather well preserved specimen with Mn-oxide coating is available in the NhM "originals collection". Measurements H HL HP D W AA AL lectotype - *11 *7 - - 37° 18° Shape — Feebly cyrtoconoidal, moderately turriculate shell of thin wall without earliest whorls and peristome. Whorls evenly convex with moderately impressed suture. Base anomphalous and meets whorl surface in rounded angular periphery. Sculpture — Earliest preserved juvenile whorls bear periodically repeating, dense, suture-to-suture, slighdy prosocline riblets that become feebly parasigmoidal on subsecjuent whorls then gradually \
