Abstract (in english)
   Echinosphaerites Wahlenberg, 1818, is one of the most geographically and stratigraphically wide-ranging Ordovician cystoids. It is abundant in the greywacke-rich Záhořany Formation (Caradocian) in the Barrandian region of Central Bohemia. The predominant Bohemian species E. infaustus Barrande 1887 has been placed by some workers in separate genus. Arachnocystites Neumayr, 1889. Restudy of the Bohemian material indicates that Arachnocystites is congeneric with Echinosphaerites, as is Deutocystites Barrande, 1887, a juvenile form. Echinosphaerites infaustus is part of a tiered echinoderm community at Záhořany. The community from +5 to 20+ cm above the sea bottom is dominated by brachiole-bearing taxa. Scanning Electron Microscope examination of E. infaustus plates clearly indicates that the respiratory structures (fistulipores) originated in the fine-mesh stereom on the sides and outer surface of the plates
