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