"Two genera of redfieldiid fishes, Redfieldius (Redfield) and Dictyopyge Lyell, are completely described and adequately diagnosed for the first time since their discovery more than a century ago. The number of Redfieldius species is reduced from seven to one -- R. gracilis. Two species of Dictyopyge are recognized, D. macrurus (Redfield) and a new species, D. meekeri, on the basis of meristic characters. According to recent palynological and paleobotanical evidence, the rocks of the Newark Supergroup containing Redfieldius are Liassic in age and those including Dictyopyge are Upper Triassic. The presence of other redfieldiids in the Newark Supergroup, first described from rocks of similar age in the western United States, is briefly mentioned. The geologic occurrence of fishes in the Newark Supergroup is discussed and a correlation chart for the major basins is included"--P. 133.
