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 RBCMAbout RBCM ( BCPMAbout BCPM 976-00382-001, BCPMAbout BCPM 976-00383-001, BCPMAbout BCPM 976-00384-001, BCPMAbout BCPM 976-00384-002, BCPMAbout BCPM 976-00385-001). No other type material is known to exist. Hydroids in three of those collections ( BCPMAbout BCPM 976-00382-001, BCPMAbout BCPM 976-00383-001, BCPMAbout BCPM 976-00385-001), formerly in fluid preservative, are now dry and in very poor condition. Those on the two slides ( BCPMAbout BCPM 976-00384-001, BCPMAbout BCPM 976-00384-002) are better, but still only marginally satisfactory. As the lectotype, we selected the colony on one of those slides ( BCPMAbout BCPM 976-00384- 002), with the other ( BCPMAbout 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).
