17 species of the ostracod genus Monoceratina Roth (including 9 new species and 1 new subspecies) are described. The new subfamily Monoceratininae, placed tentatively in the family Bythocytheridae, is erected, and taxonomic features of the genus Monoceratina are discussed. The variability, ontogenetic development and the geographical distribution of the described species are studied.

nr 1-4

Middle and Late Miocene (Late Badenian and Sarmatian) foraminifera of the epicontinental deposits of SE Poland (Roztocze area) have been examined. These deposits, referred to the Late Badenian are correlated with N13—N14 standard biostratigraphic zones, based on planktonic foraminifera. Sarmatian, therefore, especially its deeper water deposits, appears to represent younger zones. Changes in water depth appeared to control distribution of benthonic forms, whereas climatic changes and water depth controlled distribution of planktonic forms. The Middle/Late Badenian boundary probably represents an ecostratigraphic event. A correlation is suggested relating the Middle Miocene deposits of the Roztocze area with those of the Polish Fore-Carpathian Depression. Bolboforma badenensis sp. n., a planktonic form of uncertain taxonomic affinity is described.

Two lineages are distinguished in the Cenozoic anascan family Bicorniferidae, in which groups of zooecia are arranged in internodes, presumably connected by uncalcified joints. The lineage of Bicornifera is represented in the Paleocene by a species with internodes composed of four zooecia. During subsequent evolution the number of zooecia per internode was reduced to three, and the shape of the unit became more and more compact. Possibly also the size of the whole zoarium underwent reduction; in the end-member of the lineage, Bifissurinella, it was represented by a single triangular unit of three zooecia. In the second lineage of Voorthuyseniella connections between zooecia of particular branches were very fragile; consequently only isolated zooecia are found in the fossil record.

Paired, cup-like calcitic structures from the Paleocene of Pomerania, Poland, are interpreted as complete zoaria or zoarial segments of an unknown group of cheilostomatous Bryozoa. Each of the cups in the twinned unit resembles the alleged Eocene tintinnid Pseudarcella. These fossil organisms may thus represent a connecting link between the more complex segmented bryozoan of bicorniferids and the extremely simplified pseudarcellids. Geminella polonica gen. et sp. n. is proposed.

Bifissurinella cornifera sp.n. and Bifissurinella cf. triangularis Poignant et Ubaldo, 1973, are described from the Middle Miocene of the Central Paratethys. New morphological features are reported in the two species which may support the assignment of Bifissurinella to the Bryoza. The generic assignment of the described species is discussed.

Middle Miocene (Badenian) microproblematics, known as Bolboforma Daniels et Spiegler, 1974 and Bachmayerella Rögl et Franz, 1979, from the Central Paratethys (Poland, Czechoslovakia, Austria, Bulgaria and Romania) have been examined here. It has been stated that they are important for biostratigraphy, especially for distinguishing the Upper Badenian deposits from the older ones. Bolboforma taenifera sp.n. is described.

A new problematic microfossil named Aubertianella keiji gen. et sp.n. is described from the Lower Eocene (Ilerdian) of Spain and Lower Eocene (Ypresian) of Belgium. It is compared with other problematics, often considered as tintinnids; the systematic position of the discussed forms is revised.

Observations are made on the distribution and variability in the Globigerinoldes-Orbulina group in the Middle Miocene (Badenian) of Central Paratethys. The analysis of distribution and morphological diversity of planktic foraminifera versus environmental conditions prevailing in the Badenian of the studied area suggests that regional differentiation of the microfauna was controlled by bathymetric (or bathymetry-related) conditions and the stratigraphic — by climatic and, on a smaller scale, bathymetry-related ones. The differentiation is found within systematic groups (genera and species) of the analysed microfauna. In the case of foraminifera most sensitive to the above changes (representatives of Globigerinoides), it is also traceable in their final, adult morphology. The phenotypic nature is ascribed to the bioseries Globigerinoides-Praeorbulina and Orbulina or Velapertina, i.e. Globigerinoides-Orbulina group.

Ostracods of the superfamily Cytheracea from the Uppermost Cretaceous and Lowermost Tertiary of central and north Poland are studied. Of the 63 species and subspecies described, 23 species and 2 subspecies are new. One new genus, Pulaviella, is erected. The variability, ontogenetic development and sexual dimorphism of the described species are analysed. The geographical and stratigraphical distribution of studied Ostracoda and their comparison with those of Foraminifera are discussed.

The geographical range of the Montian Meridional Province in non- Alpine Europe and its foraminiferal fauna are discussed as a continuation of the authors' previous studies (Pożaryska & Szczechura, 1968 a, b; 1970). The foraminiferal fauna from the Upper Montian of the Crimea is taken as an example and compared with that of other parts of Europe. Most of the 33 species distinguished, including 3 new ones, represent stenothermal forms, analogous to those occurring in the Montian stratotype of Belgium (Puits Goffin). The geographical range of the Meridional Province, which stretches from the Pyrenees up to the Crimea in the form of an arc parallel to the northern margin of the Alpes and Carpathians, has been traced more accurately. The directions of the migration of foraminiferal faunas, within the Meridional Province whose cradle should be looked for as early as in the Upper Maastrichtian in the Belgian-Dutch basin, have been determined. These faunas reached France and West Germany in the early Montian, East Germany and Poland in the somewhat later Montian and the Crimea in the uppermost Montian. That was also the region in which the duration of a warm sea with tropical fauna was the shortest.

The taxonomic position of the genus Cardobairdia van den Bold, 1960 and its importance to the systematics of Ostracoda are analyzed. The assignment of Cardobairdia to the order Podocopida Müller, 1894 (within the superfamily Healdiaoea Harlton, 1933) is confirmed. Cardobairdia inflata n.sp. from the Middle Jurassic of Central Poland is described.

The microfauna described here come from the marine sediments of the Miocene Hommath Formation, from the west coast of the Gulf of Suez. Fifty five ostracod species have been distinguished including five new ones. The co-occurring foraminifera served as stratigraphical 'and ecological indicators. The age of the fauna has been determined as Middle Miocene though with hesitation. A similar assemblage of microfauna, especially ostracodes has been found in Miocene sediments from the Sirte Basin of Central Libya.

In this paper the authors give a summary of the Paleocene sedimentation in Poland, its facies, paleoclimatic conditions and add a description of 3 species of warm-water foraminifers, belonging to the genera Boldia van Bellen, Glabratella Dorreen and Baggatella Howe, of which Glabratella polonica and Baggatella aenigmatica are new. These species were found by the present authors in the Pamiętowo boring (Pomerania, northern Poland), in the tuffeau-type sediments of Montian age. The species described here, especially Boldia reinholdi Marie, also occur in the Montian sediments of the western European Province, the so-called Meridional (not Mediterranean) Province, including the Mons Basin, the Paris Basin and the Limbourg Province.
