part 1979 Marginulina splendens HANTKEN — SZTRÁKOS, pl. 14, fig. 1. part 1982 Marginulina splendens HANTKEN — SZTRÁKOS, pi. 12, fig. 1. Neotype — M.99.75. Type locality — Pilisborosjenő, brickyard. Type level — Kiscell Clay Formation, Upper Kiscellian. Material — One specimen (damaged). Dimensions — Length 1.6 mm, width 0.5 mm. Diagnosis — Test is elongate, circular in section. Chambers are arranged in a slight arch at the base, subsequently becomes rectilinear, and uniserial. Chambers gradually increase, generally they are broad and low, flatness gradually decreases. Sutures are distinct, oblique in the early stage, later they become nearly horizontal. Wall is calcareous, perforate, not ornamented. Aperture is terminal, radiate, its position is at the dorsal angle. Remarks — HANTKEN established this species on a single specimen. SZTRÁKOS (1978, 1979, 1982) figured variable forms as Marginulina splendens, which differ from the original in the number of chambers and the shape of test. Stratigraphical range — This species is very rare in the upper part of the Clavulina Szabói layers, Buda (Újlak) (HANTKEN 1875a-b). In Europe this species is rare, it occurs in the Middle and Upper Eocene in the Adour basin (SW France) only (SZTRÁKOS 2000). Ecology — Hemirobulina splendens is rare, it may range from neritic to bathyal zone. Genus Vaginulinopsis SlLVESTRI, 1904 Vaginulinopsis elegáns (HANTKEN, 1875) (Plate V: 19) 1875a Cristellaria elegáns n. sp. — HANTKEN, S. 88, Taf.

XIV, fig. 4. 1961 Vaginulinopsis elegáns (HANTKEN) — PAPP, S. 218. 1961 Marginulinopsis elegáns (HANTKEN) — PAPP, Abb. 6, Fig. 7. 1962 Marginulina (Marginulinopsis) elegáns (HANTKEN) — MAJZON, pi. XLII(XIV), fig. 4. 1987 Vaginulinopsis elegáns (HANTKEN) — WENGER, S. 257, Taf. 4, Fig. 11,12. Dimensions — Length about 1 mm, width about 0.2 mm (HANTKEN 1875a-b). Diagnosis — Test is elongate, earliest four or five chambers are planispirally coiled. The subsequent ones are uncoiled and uniserial, rectilinear. The test is laterally compressed, lenticular in section. Dorsal and ventral periphery is angled. Sutures are radial in the early stage, later they become nearly straight and horizontal. Wall is perforate, calcareous. Aperture is terminal, radiate, it is developed at the dorsal angle. Remarks — HANTKEN had described this species on the basis of only one specimen from the upper part of the Clavulina Szabói layers, Buda (Újlak) (HANTKEN 1875a-b). Stratigraphical range — The Vaginulinopsis elegáns occurs in the Bavarian molasse (WENGER 1987) in the Michelstettener Formation, Lower Egerian, and one specimen in the Middle Ottnangian. Vaginulinopsis minutus (HANTKEN, 1875) (Plate III: 13, Plate IV: 13) 1875a Cristellaria minuta n. sp. — HANTKEN, S. 50, Taf. XIV, Fig. 7. 1875a Cristellaria minuta — HANTKEN, p. 43, pl.

Neotype — M.99.76. Type locality — Pilisborosjenő, brickyard. Type level — Kiscell Clay Formation, Upper Kiscellian. Material — One specimen. Dimensions — length 0.6 mm, width 0.1 mm. Diagnosis — The small test is elongate, planispirally coiled in the early growth stage, involute. Later it is uncoiled, uniserial, and rectilinear. Size of the chambers gradually increases during the growth of the test. The last chamber is the largest and slightly inflated. The complete test is laterally compressed, lenticular in section. Sutures are radial in early stage, later straight and nearly horizontal. The smooth wall is calcareous and perforate. Aperture is terminal, its position is at the dorsal angle. Remarks — HANTKEN described this species on the basis of one specimen from Porva Marl (that is equivalent of the Padrag Marl Formation, Middle Eocene). No specimen remained in the Hantken collections in Hungary. Stratigraphical range — The species is known from the Middle Eocene to the Kiscellian in Hungary (HANTKEN 1875a-b; SZTRÁKOS 1978, 1979, 1982). In the Central Paratethys it occurs in the Kiscellian (ClCHA et al. 1998). This species is known in the Middle Eocene in Aquitaine (SZTRÁKOS & CASTELLTORT 2001). Ecology — The species is rare, it may range from the neritic to the bathyal depth.
