Neotype — M.99.69. Type locality — Pilisborosjenő, brickyard. Type level — Kiscell Clay Formation, Upper Kiscellian. Material — Two specimens. Dimensions — Length 0.9-1.2 mm, width 0.4 mm, and thickness 0.1 mm. Diagnosis — Test is elongate, flattened, its early stage is planispirally coiled (microspheric generation) but astacoline in megalospheric generation. Later the arrangement of the chambers becomes uncoiled, rectilinear. The chambers are broad, low and arched. The number of chambers is 12-15. Sutures arc flush. Wall is calcareous, perforate with smooth surface. Aperture is terminal, radiate. Remarks — No specimen remained in the Hantken Collections in Hungary. Stratigraphical range — In Hungary this species occurs mainly in Kiscellian (HANTKEN 1875a-b; NAGYNÉ GELLAI 1973, SZTRAKOS 1978, 1979, 1982; KORECZNÉ LAKY & NAGYNÉ GELLAI 1985). It ranges from the Upper Eocene to and Lower Egerian in the Central Paratethys (ClMERMAN & PAVSIC 1979; ClCHA ctal. 1998). Rare. In Europe this species is known from Middle Eocene (CUVILLIER & SZAKÁLL 1949; SZTRAKOS 2000) and late Eocene (BRAGA & GRÜNIG in BRAGA et al. 1975; SUBBOTINA 1953) to Lower Egerian (REISER 1987). In North Bulgaria it ranges from the end of Middle Eocene to Lower Oligocène (DARAKCHIEVA & JURANOV 1992; DARALCHIEVA 1999). Ecology — There are no ecological data. The species may range from neritic to bathyal zone, in silty

— REISER, Taf. 4, Fig. 10 1998. Amphicoryna tunicata (HANTKEN) — ClCHA et al., p. 80, pl. 25, figs. 2-3. Neotype — M.99.70. Type locality — Budapest, Újlak. Type level — Kiscell Clay, Upper Kiscellian. Material — Two specimens. Dimensions — Length 0.9 mm, width 0.2-0.3 mm. Diagnosis — Test is elongate, the juvenile chambers arc in a compressed whorl in the microspheric generation. The globular final chambers are rectilinear. Sutures are straight and constricted in the rectilinear portion. Wall is calcareous, perforate and commonly ornamented with longitudinal striae or fine ribs. The number of riblets changes between 5 and 8. The terminal, radiate aperture is at the end of a neck with some collar like processes. Remarks — No specimen remained in the Hantken collections. Stratigraphical range — The species is very rare in the upper part of the Clavulina Szabói layers, Buda (Újlak) (HANTKEN 1868, 1875a-b). It ranges from the Kiscellian to the Egerian in the Central Paratethys (ClCHA et al. 1998) and in the Bavaria (REISER 1987). Ecology — This ecological characters of this species are similar to that of Nodosaria, therefore it ranges from neritic to bathyal zone, in normal marine waters.
