Studies on western Atlantic octocorallia (Coelenterata: Anthozoa).: Part 4:: The genus Paracalyptrophora kinoshita, 1908

Previously undocumented from the western Atlantic, three new species of Paracalyptrophora are described from this region. In order to facilitate comparisons, all six species in the genus are diagnosed, illustrated, included in a dichotomous key, and compared in a table of distinguishing characteristics. P. kerberti is herein designated the type species of Paracalyptrophora. Additional specimens are reported of all six species. Paracalyptrophora is now know to occur in the central and South Pacific and both sides of the North Atlantic at depths of 150-1480 m.
