Classification The disused mixed group Gephyrea was created by Quatrefages (1847: 340) for the sub-group Siponculae (=Sipuncula) in which Quatrefages then included genera Priapule (now Priapulida) and 'Siponculides' and sub-group Echiurea (now Echiura) in which Quatrefages included genera Echiurus (now Echiuridae) and Sternaspis (now Sternaspidae). Later Quatrefages (1866: 563) treated Gephyrea as a separate group alongside Annelida. The name was widely used at varying ranks, with varying taxa membership. Baird (1868) treated it as a subclass, Parker & Haswell (1910: 491) treated it as a class in their phylum Annulata (class Chaetopoda included the polychaetes and oligochaetes). It was a well-known grouping, but Sipuncula, Echiura and Priapulida became separate phyla. Hyman (1959: 611) expressed the opinion that "the name and concept of Gephyrea must be obliterated from zoology." This seems somewhat over-emphatic, given the modest original intention of Quatrefages to find a position for what were just genera at the time . [details]

Etymology Quatrefages considered the taxa he placed in Gephyrea as intermediate in characteristics between Holothuria and Annelida. Therefore the name Géphyriens (Gephyrea) came from Greek feminine 'Gephyra, a bridge. [details]
