Late Famennian brachiopods are described for the first time from the Holy Cross Mts. (Góry Świętokrzyskie), Poland. Six taxa belong to two families, the Rhynchonellidae and the Cranaenidae; the new genus Pugnaria and three new
species (Rozmanaria magna, Pugnaria plana and Cranaena lgaviensis) are proposed. The brachiopods are dominated by the smooth and comparatively large sulcatt R. magna and the uniplicate P. plana. This macrobenthic assemblage, called Rozmanaria magna assemblage, is interpreted here as having successfully colonized deep-water habitats typical of the Chęciny-Zbrza intrashelf basin on the rising slope of the submarine ridge in the Kielce region.

Key words: Brachiopoda, Articulata, Rhynchonellida, morphology, taxa, paleoecology, Famennian, Poland.
