Figure 14 — Asterohelix urkutensis n. sp., holotype. — Refiguration of the only specimen from Úrkút (Bakony Mts) Lower(?) Sinemurian Hierlatz Limestone, misidentified with Discohelix spinicosta STOLICZKA, 1861 by SZABÓ (1984) when Asterohelix as new genus was established. Subsequent comparison to the syntypes of D. spinicosta revealed that the Úrkút specimen belongs to different species. The correction does not change the type species status of D. spinicosta, its correct figures are displayed in figure 13. Elements of Figure 14 are copied from SZABÓ (1984), fig. 2; A: spiral side, x2, B: umbilical view, X2; C: outer side X2; D: ornament of the last whorl on the spiral side, Xl4; E: ornament of the last and the penultimate whorl on the umbilical side, XlO; F: ornament of the outer side, X7.5; G: the earliest whorls in spiral view, XlO. Asterohelix urkutensis n. sp. (Figure 14) 1984: Asterohelix spinicosta (STOLICZKA, 1861) — SZABÓ, p. 68, fig. 2. Holoty p e — HGM J 10142. Type locality — Úrkút, Csárda-hegy 7 , Mn-ore mine nature conservation area; Bakony Mts, Hungary, Type strata — Lower(?) Sinemurian Hierlatz Limestone. Name — From the name of the Úrkút village. Diagnosis — Spire feebly concave; one type of ornament on juvenile and last whorl. Material — Single specimen (HGMJ 10142). Measurements H holotype 2.7 HI HPW D 11.5 W *3.3 AS 195° AU 127 e Shape — Flattened discoidal (coin-shaped) species with feebly concave spire. Carinae of outer angulations persist along full (visible) length of teleoconch. Shallow and narrow concave belt follows carinae on juvenile whorls of spire side. Whorls quadrangular and axially flattened. Sutures fine incisions, spiral one follows outline of peripheral spines along carina of outer angulation. Outer side of whorls flattened and oblique to axis; its adapical edge forms periphery of shell. No part of peristome was found. Whorls in umbilicus gradate. Initial chamber with first and half whorls feebly elevated; it can be regarded as protoconch. Its end marked by appearance of carina and first spinula at outer angulation of spiral side. Umbilical side of protoconch unknown. Sculpture — Both carinae bearing periodically repeating parabolic spines, connected to short ribs on last whorl. Number of ribs 26 on spiral and 31 on umbilical side of last whorl. Regular row of small, collabrally elongated tubercles rendering adaxial edge of whorls in umbilicus undulating. Low ridges start outward from each
