of Wortheniopsis (Sisenna) Jancsii n. sp. demonstrate a rather high morphological stability on the species level (see Figure 25). Two strongly different specimens are saved in STOLICZKA's (1861) original collection under the name "Pleurotomaria foveolatd\ One has been found also in the Bakony Alts but both are unknown in the "stable" European faunas [Wortheniopsis (Wortheniopsis) urkutensis n. sp. and Wortheniopsis (Sisenna) hierlat^ensis n. sp., respectively]. In the available material, further Wortheniopsis (Sisenna) species are also indicated, but most of them are known only in small areas of a few localities. The morphes/species of the "stable" European "faveolata" group are not or only doubtfully identifiable. Subgenus WortheniopsisJ. BÖHM, 1895 Wortheniopsis (Wortheniopsis) aff. procera (J. A.

Material — A single damaged, shelly specimen without earliest shell parts and peristome (HGM J.

08.3.1.). Measurements H HL HP HGMJ.08.3.1. **26 **15.5 *10 Shape — Rather high spired shell, consisting of convex whorls, separated by deeply impressed (subcanaliculate) suture. Whorl surface separated by rounded angulation into narrow, steep and flat ramp with concave selenizone on its abapical edge, and feebly concave, rather wide outer face. Rounded peripher}

7 gives transition into convex, narrowly phaneromphalous base. Peristome not preserved. Sculpture — Predominant ornament of spiral cords at peripheral region, and spiral threads on remaining parts of shell. Selenizone bordered also by two cords. Disregarding earliest preserved whorl, no collabral ornament beside growth-lines observable, even lunulae lacking from selenizone. Granules developed on all spiral ornamental elements but became obscure on (or eroded? from) some cords of last whorl. Strength of peripheral cords gradually decreases towards umbilicus. Remarks — The available specimen is a damaged shell, slighdy more slender than that one, figured by FISCHER & WEBER (1997) as holotype of Sisenna procera (J. A. EUDES-DESLONGCHAMPS, 1849). The ornament of the single Hierlatz Limestone (Úrkút, Bakony Mts) find is more significantly different because its spiral cords are much stronger. This might be the second known specimen in W.

Diagnosis — Turbiniform shell of whorls with lacking or obscure angulation; "ramp" feebly convex; selenizone running above flattened outer face; subregular network ornament on belt between upper suture and selenizone ("ramp"); spiral cords predominate ornament of outer face and base.
