Lingulina seminuda HANTKEN, 1875 (Plate I: 13, Plate II: 13) 1875a IJngulina costata d'ORB. var. seminuda — HANTKEN, S. 41. 1875a Lingulina costata d'ORB. var. subglabra — HANTKEN, Taf. IV, Fig. 8a-b. 1875b Lingulina costata d'ORB. var. seminuda — HANTKEN, p. 35. 1876b IJngulina costata d'ORB. var. subglabra — HANTKEN, pl. IV, figs. 8a-b. 1962 IJngulina seminuda HANTKEN — MAJZON, pi. XXXII(IV), fig. 8. 1979 Lingulina seminuda HANTKEN — SZTRÁKOS, pl. 16, fig. 2. 1982 IJngulina seminuda HANTKEN — FORAMINIFERI PADANI, Tav. XV, Fig. 4. 1998 Lingulina seminuda HANTKEN — ClCHA et al., p. 111, pl. 22, fig. 2. Neotype —M.99.60. Type locality — Budapest, Újlak. Type level — Kiscell Clay Formation, late Kiscellian. Material — Two specimens. Dimensions — Length 1.5-2 mm, width 1.2-1.6 mm. Diagnosis — Test is elongate, robust and lenticular. Chambers are uniserial, rectilinear, strongly overlapping; the final one almost reaches one-third of the test length. Number of the chambers is 3 or 4. Sutures are distinct, horizontal, slightly depressed. Wall calcareous and finely perforate. Its surface is almost smooth, two or three longitudinal costae are visible on the peripheral side. Aperture is an oval, terminal slit. Remarks — No specimen remained in the Hantken collections in Hungary. Stratigraphical range — Lingulina seminuda is rare, it occurs from the Upper Priabonian to the Upper Kiscellian in Hungary (HANTKEN 1875a-b, SZTRÁKOS 1979). It is known from the Lower Kiscellian to the Upper Eggenburgian in other areas of the Central Paratethys (ClCHA et al. 1998) and in Burdigallan in Aquitaine (CAHUZAC & POIGNANT 2002). Ecology — There are no data on the distribution of Lingulina species. Subfamily Plectofrondiculariinae CUSHMAN, 1955 Genus Plectofrondicularia LlEBUS, 1902 Plectofrondicularia striata (HANTKEN, 1875) (Plate I: 14, Plate II: 14) \%15zFlabellina striata n. sp. — HANTKEN, S. 43, Taf.

Neotype — M.99.61. Type locality — Noszvaj, Síkfőkút quarry. Type level — Buda Marl Formation, Upper Priabonian. Material — Two specimens. Dimensions — length 1.1-1.4 mm, width 0.2-0.3 mm. Diagnosis — Test is straight, lanceolate, flattened, and ovate in section. The early chambers are biserial, succeding ones are uniserial, chevron shaped. Sutures are distinct, slighdy depressed and U-shaped. Wall is calcareous, finely perforate and ornamented by 10-12 fine, longitudinal costellae. The aperture is terminal and radiate. Remarks — REISSER (1987) discussed how to distinguish P. striata from Fwndicularia égitalis NEUGEBOREN, 1850, P. muMneata CUSHMAN & SlMONSON, 1944, P. incompFRAN ZEN AU, 1888 and F. semiornata KARRER, 1877. No specimen remained in the Hantken collections in Hungary. Stratigraphical range — A few specimens occurred in the Kiscell Clay Formation in Hungary (HANTKEN 1875a-b; NAGYNÉ GELLAI 1973; SZTRÁKOS 1978, 1979, 1982). In futher parts of the Central Paratethys Plectofrondicularia striata ranges from the end of Eocene to the Late Egerian (ClCHA et al. 1975; LINDENBERG et al. in HAGN, 1981, ClCHA et al. 1998). In Aquitaine (SW France) it can be found also in Eocene (SZTRÁKOS 2000) and Chattian sediments (CAHUZAC & POIGNANT 2002). Ecology — There are no data on the distributions of the Plectofrondicularia species. Some specimens occur in the uppermost part of Buda Marl, and lower part of Tard Clay, where the O2 content has been low.
