HI, figs 1-5. Paralectotype — M.99.47. Kis-Sváb-hegy, Buda Mari Formation, Upper Eocene. Type locality — Budakeszi, Buda Marl Formation. Type level — Upper Eocene (Priabonian). Material — 204 specimens remained in Hantken Collections in Hungary (Table 4). Dimensions — Length 2.5-4.5 mm, diameter 0.7-1.2 mm. Diagnosis — The test is large, robust, cylindrical. It has short triserial stage in the microspheric generation. The megalospheric generation has a slighdy arcuate early series without distinct triserial stage. The uniserial stage is elongate. The sutures are hardly visible. The wall is coarsely agglutinated. The arjerture is rounded and terminal on a neck. Remarks — "Clavulina cylindrica rdA>TfKEN is a junior homonym of Clavulina cylindrica D'ORBIGNY, 1826. riANTKEN in POSEWITZ (Borneo. - Verl. Friedländer and S., Berlin, 1889, Nachtrag p. 383) is giving a fossil list with Clavulina cylindrica FlANTKEN = Clavulina rudilosta n. sp., but no further comments" has written RÖGL (in ClCHA et al., 1998, p.93). Stratigraphical range — "This species is so important in the Buda Marl as Clavulina Szabói in the Clavulina Szabói layers" - HANTKEN (1875a, b). In Hungary, finds range from the Middle Eocene to the Lower Egerian. It is frequent in the Buda Marl Formation, Upper Eocene (SZTRÁKOS 1982; HORVÁTH 1998). In the Central Paratethys Cylindroclavulina rudilosta occurs from Upper Eocene to Egerian (ClCHA et al., 1998). In South Bulgaria, it ranges from the Middle Eocene to Lower Oligocène pARAKCHIEVA 1999). Ecology — There are no data for Recent distribution. In fossil sediments, it is frequent in the bathyal clayey marls and marls, such as the Padrag Marl and the Buda Marl Formations in the Eocene. non 1864 Gaudryina 1868 Gaudryina 1875a Gaudryina 1875b Gaudryina 1936 Tritaxilina 1962b Tritaxilina 1978 Tritaxilina 1979 Tritaxilina 1982 Tritaxilina 1985 Tritaxilina 1988 Gaudryina 1998 Tritaxilina Subfamily Tritaxilininae LOEBLICH & TAPPAN, 1976 Genus Tritaxilina CUSHMAN, 1911 Tritaxilina hantkeni CUSHMAN, 1936 (Plate I: 11, Plate II: 11) Réussi n. sp. — STÄCHE, p. 171, Taf.

Paralectotype — M.99.48., Budapest, Újlak, Kiscell Clay Formation, Upper Kiscellian. Type locality — Budapest, Kis-Sváb-hegy. Type level — Buda Mari Formation, Upper Eocene. Material — Material: 97 specimens remained in Hantken Collections (Table 3). Dimensions — Dimensions: length 2.1-2.5 mm, width 0.4-1.2 mm. Diagnosis — The test is elongate, (^lindrical. La the early growth stage the first four or five chambers are trochospiral. Later, the number of the chambers descreases to two per whorl, the test becomes biserial. The chambers are broad and low. The sutures are distinct, elevated, frequendy thickened. The wall is thick and agglutinated. The aperture is terminal. Remarks — "Tritaxilina hantkeni CUSHMAN is a nomen novum for Gaudryina réussi (riANTKEN 1868) not Gaudryina réussi STÄCHE (1864)" - wrote RÖGL (in ClCHA et al., 1998). Stratigraphical range — It is a rather common species, œœrring in the lower and upper part of the Clavulina Szabói layers (HANTKEN 1875a, b). In Hungary, it is a typical and characteristic form of the lower part of the Buda Marl Formation (SZTRÁKOS 1978,1982). In the Central Paratethys its specimens ranges from the Upper Eocene to the Lower Egerian (ClCHA et al., 1989). In Croatia, it occurs in the Oligocène (Rupelian) (SlKIC, 1985).
