Order Foraminifera EHRENBERG, 1930 Suborder Textulariina DELAGE & HÉROUARD, 1896 Superfamily Textulariacea EHRENBERG, 1838 Family Textulariidae EHRENBERG, 1838 Subfamily Textulariinae EHRENBERG, 1838 Genus Textularia DEFRANCE, 1824 Textularia tuberosus n. sp. (Plate I: 1-2) Name — The specific name tuberosus refers to 20—30 u.m long protuberances on the test. Holotype — Eötvös Loránd University, Collection of the Department of Palaeontology. No. OP-4448. Type locality — Budapest, Mátyás-heg} 7 , western quarry. Type strata — Buda Marl Formation, Bryozoa Marl Member. Stratigraphical range in Hungary — Upper Eocene (Priabonian) Dimensions — Length of the test 500-600 urn. Width of the test at widest point 300-400 u.m. Diagnosis — Test free, wall coarsely agglutinated, biserial, elongate, length about one and half times width, oval and slighdy compressed in cross-section, periphery acute, invisible or hardly visible sutures, circular to elongate 20-30 u.m protuberances on test, aperture is an interiomarginal slit. Remarks — This species is clearly distinguishable from all other Textularia by the long protuberances on the test. Suborder Miliolina DELAGE & HÉROUARD, 1896 Superfamily Miliolacea EHRENBERG, 1839 Family Spiroloculinidae WlESNER. 1920 Subfamily Miliolinellinae VELLA, 1957 Genus Pytgo DEFRANCE, 1824 Pyrgo microstriatus n. sp. (Plate I: 3-1) Name — The specific name microstriatus refers to fine, irregularly oriented, longitudinal costae. Holotype — Eötvös Loránd University, Collection of the Department of Palaeontology. No. OP - 4300. Type locality — Csákberény 89 borehole. Type strata — Figured specimens from Csákberény 89 borehole, 307.6-309. 3 m interval and 315.3 - 318.1 meters (Csolnok Marl Formation). Stratigraphical range in Hungary — Middle Eocene (Lutetian), NP16 Zone. Dimensions — Length of the test 1000 - 1200 urn. Width of the test at widest point 700 - 900 u.m. Diagnosis —Test free, biloculine, two chambers visible in final whorl, strongly inflated, penultimate chamber slightly smaller than final chamber; wall calcareous, porcellaneous, with fine, irregularly oriented, longitudinal costae; margin rounded; aperture is a circular opening at and of the final chamber with thin tooth. Remarks — Pyrgo byramensis CUSHMAN & TODD from the Oligocène has the same shape in lateral view, but it is distinguished by the fine irregularly oriented, longitudinal costae. Pyrgo oligocenica CUSHMAN has the same shape and it has longitudinal costae, but they seem much thicker and stronger.
