34 SZABÓ, J.: Revision of Hierlatz Limestone gastropods Wortheniopsis (Sisenna) aff. lokutensis (Figure 27: A-B) 1980: Sisenna cf. procera (DESLONGCHAMPS, 1849), — SZABÓ, p. 55, pl. 1, figs 2-3 Material — A single specimen (HGM J. 08.8.1.) from Sümeg (Bakony Mts) and another from the Hierlatz Alpe. Measurements H HL HGMJ.08.8.1. **47 **30 HP **i 9 D **33 W AA 55° AL 63° Shape — Similar to that of Wortheniopsis (Sisenna) lokutensis n. sp., but juvenile whorls acute and angulation of whorls more distinct, keel like. Ramp feebly convex on juvenile shell, then gradually changes into feebly concave on last whorl, having rather wide concave band just above selenizone. Ramp narrower, outer face wider than in Wortheniopsis (Sisenna) lokutensis n. sp. Sculpture — Whorls and base covered by delicate spiral lines, being visible only with magnification. Growth-lines of similar strength cross them. First whorls of available specimen show cancellate ornament. Remarks — The somewhat acute spire and the conspicuous, keel-like angulation of the whorls suggested affinity of the species to Pleurotomaria faveolata var. procera J. A. EUDES-DESLONGCHAMPS, 1849 drawings (SZABÓ 1980), but FISCHER & WEBER's (1997) photos display a specimen as "morphe" procera that is strongly different from the first figurations. A juvenile specimen from the Hierlatz "background collection" is completely identical with the early whorl of the Sümeg shell and supports its possible new species status. Distribution — Sümeg (Bakony Mts), Upper(?) Sinemurian; Hierlatz Alpe, Upper Sinemurian (Oxynotum Zone. => Figure 27 — Wortheniopsis (Sisenna) aff. lokutensis (A-B) and Wortheniopsis (Sisenna) aff. hierlatzensis (C-D) — A: best view to display the shape of the Sümeg Wortheniopsis (Sisenna) aff. lokutensis specimen (HGMJ.08.8.1.), xl; B: back side of the specimen with best preserved details of the ornament, X3; C: the better preserved specimen (HGM J. 08.9.1.) of Wortheniopsis (Sisenna) aff. hierlatzensis, xl; D: magnified view of the same specimen to demonstrate details of the shape and the ornament, X3. Wortheniopsis (Sisenna) aff. hierlatzensis (Figure 27: C-D) 1980: Sisenna pinguis (DESLOXGCI LAMPS, 1849) — SZABÓ, p. 53, pl. I: fig. 1. Material — Two poorly preserved specimens (HGM); figured one (HGM J. 08.9.1, Measurements H HL HP Figure 27: C-D **5 Shape — Fragment of gradate shell, consisting of half whorl, being distinctly angular in spite that small size indicative of early ontogenetic stage. Ramp slighdy convex below suture, but its abapical rim concave above selenizone. Selenizone itself moderately wide, concave and mnning between two spiral cords. Abapical cord coincides with angulation. Outer face rather wide, nearly parallel to axis and having feebly concave median portion. Its lower edge D W AA AL *10 **5.5 slightly swollen next rounded-angular periphery. Base convex and seemingly without(?) umbilicus. Peristome cannot be studied in available specimen. Sculpture — Spiral and collabral threads intersect each other on shell, latter ones much weaker on base. Points of crosses bearing granules. Spiral threads (cords) most conspicuous at periphery, collabral threads (riblets) most prominent on ramp. Selenizone bears dense lunulae.
