SER 1987). In Croatia and in Italy it occurs in the Oligo- (SW France) (SZTRAKOS 2000) and the Lower Oligocène cene (Rupelian) (SlKIC 1985; FORAMINIFERI PADANI in the Lower Inn valley (SCHERBACHER et al. 2001). 1982). It was found in the Eocene in the Adour basin Hemirobulina ornata (HANTKEN, 1875) (Plate V: 16) 1875a Cristellaria ornata n. sp. — HANTKEN, S. 54, Taf. XIII, Fig. 19. 1875b Cristellaria ornata — HANTKEN, p. 77, pl. XIII, fig. 19. non 1949 Marginulina aff. ornata (HANTKEN) — CUVILLIER & SZAKÁLL, p. 65, pi. 25, figs. 22-23. 1962 Marginulina (Marginulinopsis) ornata (HANTKEN) — MAJZON, pl. XLI(XIIL), fig. 19. 1985 Marginulina ornata HANTKEN — KORECZNÉ LAKY & NAGYNÉ GELLAI, pl. XCVIII, figs. 6, 12. Dimension — About 0.5 mm (HANTKEN 1875a-b). Diagnosis — The small test is flattened, elongate lenticular in section. The six chambers are added along a slight curve. The chambers are broad and low, slightly increase as added. Suture is oblique, depressed, distinct. The dorsal periphery is angular. Wall is calcareous, perforate. Aperture is terminal, radiate, its position is at the dorsal angle. Remarks — This species differs from Vaginulinopsis because the early part of the test is not coiled. It differs from Marginulina in lack of the longitudinal costae and the ovate section. It is similar to Astacolus, but differs in the arrangement of the chambers. Stratigraphical range — Hemirobulina ornata is rare, some specimens have occurred in the Clavulina Szabói layers (HANTKEN 1875a-b) at Buda. KORECZNÉ LAKY & NAGYNÉ GELLAI (1985) mentioned this species also from the Lower Badenian, Börzsöny Mountains (North Hungary). Hemirobulina pauciloculata (HANTKEN, 1875) (Plate V: 17) 1875a Marginulina pauciloculata n. sp. — HANTKEN, S. 47, Taf. XIV, Fig. 10. 1875b Marginulinapauci-loculata — HANTKEN, p. 76, pl. XIV, fig. 10. 1949 Marginulina pauciloculata HANTKEN — CUVILLIER & SZAKÁLL, p. 67, pi. 25, fig. 36. 1962 Marginulina pauciloculata HANTKEN — MAJZON, pi. XLII(XIV), fig. 10. 1982 Marginulina pauciloculata HANTKEN — SZTRÁKOS, pl. 11, figs. 11 a-b. Dimensions — Length 1.5 mm, width 0.6 mm. Diagnosis — Test is elongate, flattened, and lenticular in section. The six chambers are added in a slight curve. The chambers are as wide as high, slighdy increase, as added. Sutures are oblique, depressed, distinct. The dorsal periphery is angular. Wall is calcareous, perforate. Aperture is terminal, radiate, placed at the dorsal angle. Remarks — HANTKEN described this species on the basis of a single specimen but no specimen was found in the Hantken collections in Hungary. Stratigraphical range — This species occurred in the upper part of the Clavulina Szabói layers, Buda (Újlak) (HANTKEN, 1875a-b). CUVILLIER & SZAKÁLL (1949) identified it also from the Aquitaine basin, Middle Eocene. Hemirobulina recta (HANTKEN, 1875) (Plate V: 18) 1875a Marginulina recta n. sp. — HANTKEN, S. 47, Taf. IV, Fig. 15. 1875b Marginulina recta — HANTKEN, p. 39, pl. IV, fig. 15. 1962 Marginulina recta HANTKEN — MAJZON, pi. XXXII(IV), fig. 15. 1973 Marginulina recta HANTKEN — NAGYNÉ GELLAI, p. 453. Dimensions — Length 1 mm, width 0.3 mm (HANTKEN 1875a-b). Diagnosis — Test is elongate, circular in section. The four chambers are inflated, added along a slight curve at the base, later becoming rectilinear. Sutures are slighdy curved, and depressed. Wall is calcareous, finely perforate, smooth. Aperture is terminal and placed at the dorsal angle. Remarks — No specimen remained in the Hantken collections in Hungary. HANTKEN established this species on a single specimen from Buda (Újlak), from the upper part of the Clavulina Szabói layers. Stratigraphical range — The species occurs in the Kiscell Clay Formation, Upper Kiscellian, only.
