Here are described 100 species, including the following seven new ones: Verneuilinoi des gorzowiensis n.sp., Quinqueloculina kozlowskii n.sp., Globorotalites polonica n.sp., AnomaHna gorzowiensis n.sp ., Lingulogavelinella pazdroae n.sp., Gavelinella (Berthe linia) lodziensis n.sp ., and Gtroetinetta (Gavelinella) varsoviensis n.sp. The subspecies Lmaiuoaavetineua asterigerinoides arachnoidea n.subsp. has also been erected. Studies on all representatives of the family Anomalinidae Cushman, 1927 has allowed the writer to extend the knowledge of the microstructure of their wall, of the alternation of generations and of the position of proloculus in the test. The results of these studies contributed to, among other things, an accurate determination of the sides of test. Almost all the species of planktonic foraminifers found have been elaborated by studying the relationships of the area discussed to the Mediterranean belt. They permitted also to establish a fine stratigraphy of the Cenomanian deposits. The ag glutinated Ioraminifers enabled the determination of the age of the beds in which the calcareous foraminifers either do not occur at all, or are very rare. Comparisons have also been conducted between the assemblages of foraminifers of Poland under study and other assemblages cited from France, north-western Germany and the platformic part of the U.S.S .R. Lithological characteristics of this area have been presented, with particular attention paid to the dependence of the occurrence of foraminifers on the type of deposits. INTRODUCTION The result of palaeontological and stratigraphic studies on the assem blages of the Upper Albian, Cenomanian and Turonian (mostly Lower) foraminifers in the Szczecin, Mogilno and Lodz Troughs and the fore-Su detic monocline are shown in the present paper. All the species ofi the family Anomalinidae found in these areas are here described, along with the representatives of selected genera of other families. A total of 100 species, including seven new ones and a new subspecies, are described. Many of these species, distributed the world over, occur both in the boreal and Mediterranean regions. Most attention has been paid to the represen tatives of the family Anomalinidae, whose dynamic development starts as late as the Albian, despite its representatives being known since the Triassic. Evolutionary series, started in the Neocomian, terminate on the ALBIAN, CENOMANIAN, TURONIAN FORAMINIFERS 5 boundary between the Lower and Upper Turonian, closing the first phylo genetic cycle of this family's development. The microstructure of wall and the alternation of generations have been studied in the species of this family . The planktonic foraminifers have also been studied almost as a whole in order to find the relationships of the area under study to the Mediterranean region. Due to their stratigraphic importance the agglu tinated foraminifers have been elaborated in the deposits in which a de creased amount of calcareous foraminifers is observed. The distribution of foraminifers has been correlated with macrofaunal horizons on the basis of Cieslinski's (1959, 1960, 1965) and Blaszkiewicz's (1970) works. The results of the writer's stratigraphic studies, here given in an ab breviated form, will be more extensively presented elsewhere. The author's studies were enabled by abundant materials coming from deep borings made in the Polish Lowland by the Geological Institute and the Oil Enterprise in 1955-1964. Altogether, foraminifers from 430 samples were elaborated, coming from the Upper Albian, Cenomanian and mostly Lower Turonian deposits, found in 16 boreholes (Fig. 1). The assemblages of foraminifers from individual tectonic units are made up in Table 1.
