The new exposure of Upper Cenomanian sediments on the lyddite-built hill of Kuchyňka near Brázdim (Bohemian Cretaceous Basin) provided a unique fauna, represented mainly by echinoids, gastropods and bivalves. The gastropod assemblage of this locality is described in this report. Fossils were collected during the spring 1999 and the autumn 2001 and total number of gastropod samples in 201. Gastropod fauna consists of 30 species belonging to 16 genera, of which 4 species are questionably assigned and 2 species have been not determined yet. Also 2 specimens of gastropod operculum were found. Described gastropods consist of archaeo-, meso- and opisthobranch gastropoda which occupy about 45 per cent, 49 per cent and 6 per cent of the total number of species respectively. A brief description of mode of life of some recognised species is presented here.
