Type locality. Canada, British Columbia: near Round Island in Dodd Narrows (Fraser 1914a).
Current status. Invalid.
Remarks. Fraser did not designate a name-bearing type of Clytia longitheca in his original description of the species. In choosing a lectotype, we examined several syntypes of this hydroid in the Fraser Hydroid Collection at the RBCM (BCPM 976-00382-001, BCPM 976-00383-001, BCPM 976-00384-001, BCPM 976-00384-002, BCPM 976-00385-001). No other type material is known to exist. Hydroids in three of those collections (BCPM 976-00382-001, BCPM 976-00383-001, BCPM 976-00385-001), formerly in fluid preservative, are now dry and in very poor condition. Those on the two slides (BCPM 976-00384-001, BCPM 976-00384-002) are better, but still only marginally satisfactory. As the lectotype, we selected the colony on one of those slides (BCPM 976-00384- 002), with the other (BCPM 976-00384-001) assigned paralectotype status. Dry samples of the species, mentioned above, are included as paralectotypes.
Fraser (1914a) intended at first to assign this species to Campanularia Lamarck, 1816, as C. longitheca. After the manuscript had gone to press, he discovered material with gonothecae bearing nascent medusae, and in a footnote of the published paper correctly assigned it instead to Clytia Lamouroux, 1812, as C. longitheca.
Calder (1971) and Cairns et al. (2002) regarded Clytia longitheca Fraser, 1914a as a probable synonym of C. paulensis (Vänhoffen, 1910). Peña Cantero & García Carrascosa (2002) treated the two as conspecific, an opinion currently upheld in WoRMS. An extensive synonymy of C. paulensis was given by Medel & Vervoort (2000).
