  <dc:description>&lt;p&gt;Different adductor muscle attachment scar patterns of the three ostracode genera &lt;i&gt;Darwinula&lt;/i&gt; Brady and Robertson, 1885, &lt;i&gt;Gutschickia&lt;/i&gt; Scott, 1944, and &lt;i&gt;Whipplella&lt;/i&gt; Holland, 1934, from Pennsylvanian and Permian rocks of 'West Virginia are illustrated for the first time. &lt;i&gt;Gutschickia&lt;/i&gt; and &lt;i&gt;Whipplella&lt;/i&gt; have been considered as junior synonyms of &lt;i&gt;Carbonita&lt;/i&gt; Strand, 1928, and the oldest darwinulid scar pattern previously known was from the Upper Triassic of Germany. The different patterns document the presence of &lt;i&gt;Darwinula&lt;/i&gt; in the Pennsylvanian of the United States and indicate that &lt;i&gt;Whipplella&lt;/i&gt; and &lt;i&gt;Gutschickia&lt;/i&gt; are valid genera. The use of ostracodes in discriminating between Carboniferous and Permian continental sedimentary rocks should be based on restudy of the species in these genera.&lt;/p&gt;</dc:description>
