Lectotype — GELLAI-NAGY (1988) pl. VIII, figs. 1-3. Type locality — Budapest, Újlak. Type level — Kiscell Clay Formation, Late Kiscellian. Paralectotype — M.01.18. Budapest, Újlak, Kiscell Clay Formation, Late Kiscellian. Material — 30 specimens remained in the Hantken collections in Hungary. Dimension — Diameter 2.5—4 mm. Diagnosis — Test is enrolled, planispiral, lenticular, biumbonate and having an umbonal boss. Periphery is angular and bears a keel. Chambers are rather broad and low, their dimensions increase with low rate. Sutures incline to the proloculus. Wall is calcareous, hyaline and perforate. Aperture is radiate. Remarks — There is no significant difference between L arcuata and L cultrata in the figures of SZTRÁKOS (1978, 1979). Stratigraphical range — Lenticulina arcuatostriata ranges from the Middle Eocene to the Lower Miocene in Hungary (HANTKEN 1868, 1975a-b; NAGYNÉ GELLAI 1973; SZTRÁKOS 1978, 1979, 1982; HORVÁTH 1980), and from the Middle Eocene to end of the Eggenburgian elsewhere in the Central Paratethys (BRESTENSKA & LEHOTAYOVÁ 1983, ClCHA et al. 1998). It is frequent also in other parts of Europe [for example Middle Eocene in Aquitanian basin (CUVILLIER & SZAKÁLL 1949); Priabonian in North Italy (HAGN 1956; BRAGA & GRÜNIG in BRAGA et al. 1975); Oligocène (Rupclian) in Croatia (SlKIC 1985, ClMERMAN & PAVSIC 1979), in Bavaria (HAGN in HAGN & MARTINI, 1981); Lower Oligocène in Lower Inn valley (SCHERBACHER et al. 2001)]. Ecology — This species is an epifaunal, probably detritivore, normal, cold marine, bathyal taxon. It is a typical and frequent element of the bathyal sediments in Upper Eocene and Oligocène. Lenticulina baconica (HANTKEN, 1875) (Plate V: 7) 1875a Robulina baconica n. sp. — HANTKEN, S. 58, Taf. XIV, Fig. 9. 1875b Robulina baconica — HANTKEN, p. 49, pl.XIV, fig. 9. 1949 Robulus baconicus (HANTKEN) — CuviLLiER & SZAKÁLL, p. 57, pi. 21, fig. 22. 1962 Robulus baconicus (HANTKEN) — MAJZON, pi. XLII(XIV), fig. 9. Dimension — Diameter is about 1 mm (HANTKEN 1875a-b). Diagnosis — Test is planispirally coiled, lenticular and biumbonate. The broad and low chambers increase in low rate, the final ones are stretched. The number of the chambers is eight in the last whorl. Sutures are distinct, curved, elevated, and narrowing toward the margin. Wall is calcareous, perforate and smooth. Umbos are covered and ornamented by nodes. Aperture is radiate at the peripheral angle. Remarks — No specimen were prserved in the Hantken collections in Hungary. Stratigraphical range — This species is very rare in the lower part of the Clavulina Szabói layers, at Porva (= Padrag Marl Formation) (HANTKEN 1875a, b). CUVILLIER & SZAKÁLL (1949) had written the species in the Aquitaine basin, from Lutetian to Miocene.
