SZABÓ,J.: Revision of Hierlatz Limestone gastropods Chartronella? noszkyi SZABÓ, 1982 (Figure 70) 1982: Chartonella noszkyi sp. n — SZABÓ, p. 22, pi. 2, figs 7-8. Material — Three rather well preserved shelly specimens (HGM, holotype: J 10132). M e a s ti re ments H holotype *24 HL 16 HP 12 B Figure 70 — Chartronella? noszkyi SZABÓ, 1982, refiguration of the holotype. — A-B: apertural and dorsal views, xl; C: magnified dorsal view to show the ornament, X3. Shape — Dextral, moderately high turbiniform, thick-walled shell. Surface of whorls convex and divided into three flattened, longitudinal belts, being roughly equal in width; uppermost one of these forms narrow ramp. Suture running just on lower edge of lowermost D 19.5 .D AA 69° AL 69° band. Base convex and anomphalous. Peristome rounded, prosocline, particularly at its outer lip (being damaged but its orientation given by growth-lines). Narrow and shallow furrow separates moderately thickened inner lip from low basal ridge, running from parietal lip to foot of columella. Sculpture — As strongest spiral ornamental elements, three carinae visible on last whorl, just on angulations, separating flattened bands. On earlier whorls, lowermost carina just overlapped by suture. Other, weaker cords also present on juvenile shell, but disappear on penultimate whorl. Besides these, fine, dense threads both on base and spire observable. Growth-lines prosocline, slightly sigmoidal on whorls and parasigmoidal on base. Remarks — On the basis of the rather gradate outline and the tricarinate last whorl (and bicarinate preceding ones) Chartronella noszkyi is distinguishable from the majority of its congeners. A comparable species is HUDLESTON's (1894) "Trochus spiratus D'ACHIAC", especially the specimen on pl. XXXI. fig. 7 having a tricarinate last whorl, but differs by its somewhat cyrtoconoidal shape and a suture less deep than in Chartronella noszkyi. Moreover, the secondary spiral sculptural elements are rarer and stronger, than in Chartronella noszkyi. Distribution — Fplény (Bakony Mts), Upper Pliensbachian. Family Nododelphinulidae COX, 1960 Genus Cuidonia DE STEFAN I, 1880 Type species: Trochus rotu/us STOIJCZKA, 1861 [suggested by HAAS (1953) to fix a type species to Cuidonia beacause of unsolvable nomenclatorial troubles around the originally selected "Trochus ot Turbo Songavatir STOPPANl]. Remarks — Cuidonia belongs to the genera that are somehow missing from the well known handbooks, targeting classification of gastropods. HAAS (1953) suggested a tentative systematic place in Pleurotomarioidea (Trochonematidae), similarly to the former authors, however, he expressed his opinion that no pleurotomarioidean relation were indicated by the shell morphology. Actually, the shell morphology is just slightly different from that of Trochonema, but it is meaningful for classification: no sinus band or row of lunulae are recognisable on the shells of Cuidonia. Therefore, a Trochoidean systematic position seems to be more correct. GRÜNDEL (2004) regarded Cuidonia as member of Liotiidae (Trochoidea). However, on the basis of the bicarinate whorls and the gradate shell outline, here the family Nododelphinulidae is thought as the best systematic place for Cuidonia. The shell shape resembles also typical Chartonella and this indicate a possible accomodation in another family.
