10 HOF Dimension — Length 1 mm (HANTKEN 1875 a-b). Diagnosis — Test is elongate and slightly arcuate. Its chambers are longer than wide. Their number is five only. Proloculus is fusiform, subsequent chambers are differendy sized. Sutures are straight and horizontal. Wall of the test is smooth. Aperture is terminal, close to the apex (after HANTKEN^ description). Remarks — No specimen remained in the Hantken collections in Hungary. Stratigraphical range — The species is very rare in the Kiscell Clay, only in the upper part of the Clavulina Szabói layers (HANTKEN 1875a- b).

XI, fig. 8. Dimension — Length 0.5 mm (HANTKEN 1875a-b). Diagnosis — Test is small, elongate, arcuate and uniserial. Proloculus is rounded. Chambers increased gradually during ontogenesis. Wall is calcareous, hyaline and finely perforated. Sutures are oblique and slighdy depressed. Aperture is terminal and consisting of several radial slits. Remarks — No specimen remained in the Hantken Collections in Hungary. Stratigraphical range —• The species is very rare in the upper part of the Clavulina Szabói layers, Budapest (Újlak) (HANTKEN 1875a-b). SZTRÁKOS (1978, 1979) found a specimen in the Lower Kiscellian of the Farkasrét Cemetery (Budapest). KORECZNÉ LAKY & NAGYNÉ GELLAI (1985) identified L, debilis also in the Oligocène sediments of the Börzsöny Mountains. This species ranges from Middle to Upper Eocene of the Adour basin (SW France, SZTRÁKOS 2000).

Neotype — M.99.56. Type locality — Noszvaj, Síkfőkút. Type level — Upper part of the Buda Marl Formation, Lower Kiscellian. Material — One specimen. Dimension — Length 2-3 mm. Diagnosis — Test is elongate, uniserial, slightly arcuate and it has a rounded proloculus. Sutures are straight and horizontal. Wall is calcareous, hyaline and extreme finely perforate. Aperture is terminal, it consists of a series of radial slits close to the apex. Remarks — SZTRÁKOS (1982) figure differs from the original one in a fatter test and in the number of chambers. Stratigraphical range — L. intermedia occurs only sporadically in the upper part of the Clavulina Szabói layers (HANTKEN 1875a-b) in the Kiscellian (SZTRÁKOS 1979). Ecology — The species ranges from the neritic to the bathyal zone. Laevidentalina simplex (HANTKEN, 1868) (Plate I: 8, Plate II: 8) 1868 Dentalina simplex n. sp. — HANTKEN, p. 87, pl.

Material — One specimen. Dimension — Length 0.8 mm. Diagnosis — Test is elongate, slightly arcuate with rounded proloculus. Younger chambers are uniserial, equal in size. Sutures are straight and slighdy oblique. Wall is calcareous, hyaline and finely perforate. Aperture is composed of a series of radial slits nearby the apex. Remarks — No original specimen has been found. Stratigraphical range — L. simplex is very rare in
