THE BRITISH DEVONIAN CRINOIDEA

摘要

In Part 2, we describe the British Devonian crinoids of the subclasses Cladida (15 genera, 29 species) and Disparida (three genera, four species), and morphotaxa based on disarticulated columnals and pluricolumnals (11 morphogenera, 14 morphospecies), including those taxa left in open nomenclature, and other, unnamed fragments (seven species). One new nominal morphospecies is described, namely Sidericrinus (col.) plymouthensis sp. nov., and a new genus of cladid, the poteriocrinine Eopachylocrinus gen. nov.
