Telleria (Telleria) picea SZABÓ, (1983) 1983: Ochetochilus piceus SZABÓ, p. 43, Fi. III. figs 1-4. Remarks —• Possessing an umbilicus, this species do not belong to the subgenus Ochetochilus but to Telleria, in which a comparable species has already been described : T. (T.)petri (PARONA 1894). It is necessary to make a distinction between them. T. petri has a nearly conical shell with deeper suture, and an acute apex while the spire in T. picea is ovate with shallower suturai furrow and blunt apex. The apical angle is wider (~ 20°; in the latter one. The ornament of Telleria petri consists of delicate spiral lines equal in strength but Telleria picea has strong spiral lathes together with intersecting finer threads between the stronger pairs. A distinction between T. picea and T. benacensis was given above. Distribution: Somhegy, condensed Subfurcatum to Garantiana Zone. Genus PARONAELLA CONTI et FISCHER, 1984 Type species: Paronaella subcylindrica (PARONA, 1894), [Ceritella (Fibula ) subcvliindrica PARONA, 1894; p. 381, PL I: fig. 22.] Diagnosis —• High subcylindrical-pupifcrm shell; numerous hardly convex whorls, ornamented by fine spiral threads and slightly opisthocyrt-prosocline growth-lines. Aperture elongated axially, peristome entire; columellar lip sraight. Narrowly phaneromphalous, convex base. Callus of moderate extent, covering the umbilicus partially. Remarks — Paronaella was described originally as a subgenus of Telleria but the remarkably different shape supports the independent generic position. The former opinion was suggested on the basis of the peristomial characters. Genus DIA TRYPESIS TOMLIN, 1929 Remarks — The presence of spiral ornament on Diatrypesis angulocostatum (see below) makes necessary to correct the diagnosis of this genus (given by WENZ 1940). As the example of Proconulus epuliformis has shown it, the presence or absence of a spiral lineation has only low taxonomic value. Its importance is questionable even at the species level. So Diatrypesis may contain forms with spirally lineated shells, too, if it is the only disagreement with the earlier definitions. Diatrypesis anguloccsíaíum (SZABÓ, 1983) 1983: Procerithium (Cosmocerithium) ? angulocostatum SZABÓ, p. 39, PL II: fig. 7. 1984: Diatrypesis settepassii CONTI et FISCHER, p. 134, Pl. V: figs 9-15. Remarks — The Case Canepine specimens complete well the original description because many of them have embryonal shell, too, that did not occurred in the Somhegy material. Distribution — Somhegy, Humphriesianum? and condensed Subfurcatum to Garantiana Zone; Case Canepine, Humphriesianum. Family Lameiliphoridae KOROBKOV, 1955 Lamelliphorus rhombifer (UHLIG, 1881) 1881 : Trochus (Carinidea) rhombifer UHLIG, p. 405, Pl. VII: figs 15-16. 1983: Lamelliphorus rhombifer (UHLIG, 1881) — SZABÓ, p. 35, Pl. I : figs 14-15. 1984: Lamelliphorus reticulatus CONTI et FISCHER, p. 155, Pl. IV: figs 25a-b. Remarks —On the Case Canepine specimen, the peripherial carina is well visible on the spiral whorls, too, because the suture does not cover it. The orientation of the nearly axial apparent ribs is also somewhat different from that of the other specimens. They are orthocline in the beginning and become prosocline only later. The two apparent rib types are of the same srength in the Case Canepine and Bakony specimens while Uhlig's figures show the dominance of the nearly axial ones. The base of the Case Canepine specimen is covered by fine spiral lines. This lineation is lacking from the others. New, well preserved material is necessary to clear up the real meaning of the described differences. Distribution — Babierzówka (Western Carpathians), ? Upper Callovian (certainly mixed fauna) ; Somhegy, ? Parkinsoni Zone (or Lower Bathonian); Case Canepine; Humphriesianum Zone.
