Some anthoathecate hydroids and limnopolyps (Cnidaria, Hydrozoa) from the Hawaiian archipelago

  title={Some anthoathecate hydroids and limnopolyps (Cnidaria, Hydrozoa) from the Hawaiian archipelago},
  author={Dale R. Calder},
A systematic account is given of 17 families, 25 genera, and 32 species of anthoathecate hydroids and limnopolyps reported from Hawaii. Applying Reversal of Precedence provisions in zoological nomenclature, the familiar hydrozoan genus names Hydractinia Van Beneden, 1844a, Bimeria Wright, 1859a, and Porpita Lamarck, 1801 are designated as valid and as nomena protecta, while seldom-used older names threatening them (the synonyms Echinochorium Hassall, 1841 and Manicella Allman, 1859a, and the…

The European athecate hydroids and their medusae (Hydrozoa, Cnidaria): Capitata Part 1

A re-examination of the type material of Eudendrium elsaeoswaldae Stechow, 1921 revealed that it is conspecific with E. ramosum and newly collected material from the type locality confirmed this.

Additions to the hydroids (Cnidaria) of the Galápagos, with a list of species reported from the islands

The hydroid fauna of the Galápagos Islands, Ecuador, is known largely from reports of collections made between 1932 and 1938 during several Allan Hancock Pacific Expeditions, but an additional 15 species are added here, based on collections undertaken between 1992 and 2000.
