Article: Phyllocarid crustaceans from the Silurian and Devonian of Czechoslovakia
Recent discoveries of phyllocarids in the Silurian and Devonian of the Barrandian area in Bohemia and the Upper Devonian of the Moravian Karst area are described. Nearly complete specimens of Aristozoe parabolica Perner and Pygocaris schuberti Perner have been found, permitting a more detailed diagnosis of the family Aristozoidae, to which the genus Heroldina Broili has also been referred. Ceratiocaris cornwallisensis damesi subsp. nov. from the Czech Silurian and Ceratiocaris (?) coherbaria sp. nov. from the Middle Devonian are described.Concavicaris desiderata (Barrande) from the Czech Middle Devonian and C. incola sp. nov. from the Moravian Upper Devonian are described and assigned to the genus Concavicaris Rolfe (formerly Colpocaris Meek), previously known only from the American Carboniferous. The systematic position of the genus Montecaris Jux is discussed and the description of M. brunnensis Chlupac is amplified.
