Astacolus irregularis (HANTKEN, 1875) (Plate V: 13) 1875a Cristellaria irregularis n. sp. — HANTKEN, S. 50, Taf. XIV, Fig .2,3. 1875b Cristellaria irregularis — HANTKEN, p. 42, pl. XIV, figs. 2,3. 1962 Marginulina irregularis (HANTKEN) — MAJZON, pi. XLII(XIV), fig. 2,3. 1982 Marginulina irregularis (HANTKEN) — SZTRÁKOS, pi. 11, figs. 9a-b, 10. Diagnosis — Test is elongate, ovate in section and flattened. Chambers are broader than height. They are arranged along a slightly curved axis in the early growth stage, later uncoiling by HANTKEN'S diagnosis. The early sutures are strongly oblique, later ones slighdy. The dorsal periphery less, the ventral one is more strongly rounded. Wall is calcareous, perforate and smooth. Aperture is terminal, placed at the dorsal angle. Remarks — No specimen remained in the Hantken collections in Hungary. Stratigraphical range — A. irregularis is very rare in the lower part of the Clavulina Szabói beds (two specimens), Buda (Kis-Sváb-hegy) (HANTKEN 1875a-b). SZTRÁKOS (1982) mentioned this species without data of occurrence. Astacolus porvaensis (HANTKEN, 1875) (Plate V: 14) 1875a Cristellaria porvaensis n. sp. — HANTKEN, S. 50, Taf.

. Dimensions — Length is about 0.8 mm, width 0.2 mm (HANTKEN 1875a-b). Diagnosis — Test is elongate, ovate in outline and flattened. The six to ten chambers are broad and low, added along a slightly curved axis in the very early stage, later uncoiling. Sutures are slightly oblique in the early stage, later straight. Wall is calcareous, perforate, and smooth. Small granulae cover the sutures. Periphery is angular. Aperture is radiate, its position is at the dorsal angle. Remarks — No specimen remained in the Hantken collections in Hungary. Stratigraphical range — Astacolus porvaensis is not rare in the lowermost part of the Clavulina Szabói layers, Porva Marl (HANTKEN 1875a-b), recently is equivalent to the Padrag Marl Formation, Middle Eocene. In Croatia this species is known from the Eocene (DROBNE 1979).

Diagnosis — Test is elongate, circular in section. Four or six chambers are added along a slight curve. Rapidly increasing chambers become rectilinear later. Sutures are oblique, they may be slighdy depressed. Wall is calcareous, hyaline, perforate and smooth. Aperture is terminal, radial, placed at the dorsal angle. Remarks — "Marginulina hantkeni BANDY" was introduced as new name for Marginulina subbullata HANTKEN (1875) non Marginulina subbullata GÜMBEL (1868) — RÖGL in ClCHA etal. (1998). No original specimen was found in Hungary. Stratigraphical range — This species occurs in the Kiscell Clay Formation, Kiscellian in Hungary (HANTKEN 1875a-b; NAGYNÉ GELLAI 1973, SZTRÁKOS 1982; KORECZNÉ LAKY & NAGYNÉ GELLAI 1985). Rare. Hemirobulina hantkeni ranges from the Upper Eocene to the Egerian in the Central Paratethys (ClCHA et al 1998). In the Bavarian molasse it ranges from the Upper Rupelian (Upper Kiscellian) to the Lower Egerian (REI-
