Abstract
The radiate structures in the shell of Paleozoic ostracodes are interpreted to be epigenetic in origin. On the basis of this interpretation, the genus Radiicypridina Bless, 1973, is a junior synonym of Eocypridina Kesling and Ploch, 1960. The type-series of Eocypridina radiata (Jones, Kirkby, and Brady, 1874), from the Coal Measures of Scotland, is illustrated, and a lectotype is designated. Eocypridina aciculata, (Scott and Summerson, 1943) is a valid species, but the more elongated specimens they identified as Cypridina radiata Jones, Kirkby, and Brady, 1874, from the same collection, belong in E. aciculata. The variation in lateral outline of specimens in the Hance Formation of Kentucky is due to the orientation of the valves in the rock.
