  • 摘要:Three new species of the genus Spathacalymene Tillman are described and figured on the basis of a rich material from the Goldap,Mielnik and Terespol boreholes,situated in Cucullograptus hemiaversus,C. aversus and Saetograptus leintwardinensis zones of the platform area. Furthermore,Calymene nodulosa Shirley,1933 and Calymene pompeckji Kummerow,1928 are assigned by the present writer to the genus Spathacalymene Tillman,1960. The relationships of Spathacalymene to other genera within the Calymeninae are discussed. The stratigraphic range of the trilobites described is very narrow and they are considered to be important index fossils of the uppermost part of the Lower Ludlovian.
