Two new species of <em>Bargmannia</em> (Pyrostephidae, Physonectae, Siphonophorae)
No full textTwo new deep-living species of the genus Bargmannia (Siphonophorae, Physonectae, Pyrostephidae) are described based, almost exclusively, on the nectophores of single specimens collected by ROVs off the west coast of California. The nectophores of B. stenotes sp. nov. were relatively small, up to 11.4 mm in length and, in the preserved condition had very narrow nectosacs. There was a marked bend in the distal part of the preserved nectophore, resulting in the ostium opening upwards. The mature nectophores of B. profunda sp. nov. were almost twice as long as those of B. stenotes and were characterised by the fact that the lower lateral ridges did not join, distally, with the meso-lateral ones. This feature also was present in smaller nectophores of B. amoena but those of B. stenotes, at that stage, did not have a mouth-plate
A history of the sub-order Cystonectae (Hydrozoa: Siphonophorae)
No full textThe siphonophore sub-order Cystonectae presently comprises just five species in three genera and two families, and includes Physalia physalis, the Portuguese Man O’War. Despite the smallness of the group its history has been very chequered, particularly for P. physalis, which has been described under more than fifty different names. Haeckel (1888) was one of the worst offenders regarding the description of questionable species, but even Totton (1965) was uncertain as to the validity of some previously described cystonect species. Herein, an attempt has been made to review the history of the sub-order Cystonectae and to clarify its taxonomy. A list of synonyms for each recognised cystonect species is given in an appendix
