Remarks — The difference between Vulvulina subflabelliformis (HLANTKEN 1875a) and Vulvulina haeringensis (GÜMBEL, 1868) is proved in the juvenile stage, when the aperture is a split at the base of the ar^rtural face. In the adult forms the aperture becomes an mteriomarginal arch with parallel the side of the test. Stratigraphical range — It is frequent in the Clavulina Szabói layers, in all sections of IdANTKEN (1875a, b). In Hungary it has been found from the Middle Eocene to Oligocène, mainly Upper Eocene and Upper Kiscellian (SZTRÁKOS 1979; HORVÁTH 1998). In Possagno section it occurs in the Lower and Middle Eocene (PROTO DECIMA & De BlASE in BRAGA et al. 1975), and Upper Eocene in Bavaria (HAGN 1960). Ecology — There are no data for its distributions in the Recent seas. In Eocene and Oligocène it occurs together with typical bathyal agglutinated and calcareous forms, such as Reticulophragmium, Planulina.

Lectotype — GELLAI-NAGY (1988) pl. II, figs 3-5. Paralectotype — M.99.44. Budapest, Buda, Vár-hegy, Buda Marl Formation, Upper Eocene. Type locality — Budapest, Buda, Vár-hegy. Type level — Buda Marl Formation, late Eocene. Material — 42 specimens (Table 2). Dimensions — Length: 2-4 mm, width (on the upper part): 1-2 mm. Diagnosis — The test is elongate, stout, its early stage has triserial and triangular cross-section that becomes biserial and rounded later. The size of the chambers increases very slowly therefore the test has nearly parallel sides. The wall finely is agglutinated, solid The arjerture is an arch in the inner margin of the final chamber. Remarks — RÖGL (in ClCHA et al. 1998) has written: "The designated leaotype (GELLAI-NAGY 1988) is comparable with FLANTKEN'S material in the NFLM collection in Vienna, and it is triserial and triangular in section; the triserial stage later becomes biserial." Stratigraphical range — HANTKEN collected this species from Piszke Marl (recently equivalent with Padrag Marl Formation; BERNHARDT B., personal com.) and the Buda Marl Formation (1871,1875a, b). In Hungary it occurs only in the Eocene Padrag and Buda Marl Formations. Rare. La the Central Paratethys this species ranges from Middle Eocene to Upper Oligocène (ClCHA et al. 1998). Ecology — It is a normal marine, epifaunal, suspension feeder form, living on hard substrat. The different Gaudryina species range from 50 to 500 m depth, from shelf to bathyal zone (MURRAY 1973, 1991). In the Kiscell Clay and Buda Marl Gaudryina textilaroides ranges in the bathyal zone.
