Abstract: 

84 species belonging to 25 genera are described. They are distributed in the families: Spiroloculinidae (Palaeomiliolina, Quinqueloculina), Milioliporidae (Kamurana, Galeanella, Miliolipora), Ichtyolariidae (Austrocolomia, Pachyphloides, Frondina, Grillina), Robuloidiidae (Falsopalmula, Ichtyolaria), Nodosariidae (Dentalina, Nodosaria, Pseudonodosaria, Lingulina, Lenticulina, Astacolus, Vaginulinopsis, Vaginulina), Polymorphinidae (Eoguttulina), Duostominidae (Diplotremina, Duostomina, Variostoma), and Oberhausereliidae (Oberhauserella, Schmidita). In the article the Loeblich, Tappan’s (1988) classification is applied. The foraminifers here presented derived from 55 boreholes and 30 outcrops from different regions of Bulgaria.
