16 HoRvA bonate and compressed. The relatively broad and low chambers increase slowly in size as added. Sutures are oblique. Wall is calcareous, perforate, but small nodes cover the perforation. Aperture is radiate at the peripheral angle. The periphery itself is angular with a wide rim. Remarks — It is not rare in the lowermost part of the Clavulina Szabói layers, on the south-western part of , M. the Transdanubian Central Range (HANTKEN 1875a-b). Stratigraphical range — Lenticulina granulata ranges from the Upper Eocene to the Lower Oligocène in North Bulgaria (DARAKCHIEVA 1999) and from the Middle to the Upper Eocene in Aquitaine (France) (SZTRÁKOS 2000). Ecology — The species is epifaunal, normal marine, cold water dweller, and bathyal species, typical in clay facies.

XLII(XIV), fig. 11. 1956 Robulus porvaensis (HANTKEN) — HAGN, S. 126. 1982 Lenticulina ci. porvaensis (HANTKEN) — SZTRÁKOS, pl. 10, figs. la-b. Dimension — Diameter is about 1 mm (HANTKEN 1875a-b). Diagnosis — Test is planispirally coiled, only the last ten to twelve chambers can be seen. The test is stretched and lenticular. The younger chambers are more stretched than the older ones. On both sides small bosses cover the umbilicus. The dorsal periphery is angled. The chambers are broad and low, their size increase slowly as following each other. Sutures are distinct and radial. Wall is calcareous, perforate and has no ornamentation. Aperture is radiate and lying at the peripheral angle. Stratigraphical range — It is very rare, only in the lower part of the Clavulina Szabói layers (HANTKEN 1875a-b), in the Padrag Marl Formation, Middle Eocene. There are few data about its occurrence from the Upper Eocene (HAGN 1956; SZTRÁKOS 1982).

Type locality — The top of the Kis-Sváb-hegy. Type level — Buda Marl Formation, Upper Eocene. Paralectotype — M.99.65 (broken). Kis-Sváb-hegy, Buda Marl Formation, Upper Eocene. Material — One specimen (broken). Dimension — Length 2-4 mm, width 1-1.2 mm. Diagnosis — Test is elongate, somewhat flattened, early part coiled. Chambers are broad and low. Sutures are distinct, depressed, oblique and curved. Wall is calcareous, hyaline and perforate, without any ornament. Aperture is radiate, terminal at the dorsal angle, proceed on a small neck. Remarks — In the Hantken Collections, one specimen has been preserved. It differs from Vaginulinopsis species in the smooth wall and peripheral keel. Stratigraphical range — Percultazonaria schwageri occurs mainly in Buda Marl and Kiscell Clay, in Hungary, from the Upper Eocene to the Oligocène (HANTKEN 1875a-b; SZTRÁKOS 1982; NAGYNÉ GELLAI 1973). In other parts of Europe this species is known also in the Eocene (MATHELIN & SZTRÁKOS 1993) and in the Oligocène (LÜHR 1962). Ecology — There are no data about the distribution.
