the Bakony Mts, the juvenile specimens of P.? epuloides Distribution — Chiusa Sclafani (Sicily), Upper SZABÓ, 1981 cause difficulty in the distinction. Above the Pliensbachian; Sümeg, Upper(?) Sinemurian; Lókút, Kericser, measurements, P.? epuloides always has sharp periphery. Lower Pliensbachian (Ibex Zone), (Bakony Mts).

Proconulus? epuloides SZABÓ, 1981 (Figure 67: A-D) 1981: Proconulus epuloides sp. n. — SZABÓ, p. 56, pl. 1, figs. 2-3. Material — One of the 22 specimens is inner mould, the others are shelly specimens, of which some are excellently preserved (HGM, holotype: J 10121). Measurements H HL HP holotype 36.5 11.5 6.5 Shape — Dextral, high conical or feebly cyrtoconical spire with somewhat acute juvenile shell. Whorls flat, except last ones of adult specimens, being slightly concave. Peripher}' sharply angulate, like carina, on adult specimens. Base flattened, anomphalous, aperture strongly prosocyrt with conspicuously opisthocyrt basal lip. At foot of columella, distinct, narow "C'-shaped callus developed on base along basal lip. Sculpture — Shell smooth, "ornament" consisting of fine growth lines, being strongly prosocline between sutures and opisthocyrt (sickle-shaped) on base. Adult whorls and mainly base show some obscure spiral lines, too. Remarks — The shape of the shell is similar to that of the Epulotrochus species but there is a considerable "C"-shaped callus at the foot of columella D W AA AL 19.5 9.5 35° 27° along the adaxial part of the basal lip. Because of this, SZABÓ (1981) identified this species as Proconulus in the original designation. However, this shell part has a different morphology in the typical Proconulus; first of all there is a true columellar lip in this genus, but it is so short in Proconulus? epuloides that it is practically equal with the absence. The callus-like, widened part in Proconulus is part of the outer face of the columellar lip, sometimes extending also to the basal lip, but the callus of Proconulus? epuloides is secreted onto the base along the adaxial part of the basal lip. This form may represent a new genus. Distribution — Lókút, Kericser, beds with mixed Obtusum to Ibex Zone fauna, and higher Pliensbachian; Lókút, Fenyveskút, and Eplény, both Upper Pliensbachian (all in the Bakony Mts).
