Syntypes . BCPM 976-00228-001: Japan , Sagami Bay, Eboshi-iwa, low tide, 19 April 1931 , several colony fragments, up to ca. 2 cm high, in rather poor condition, some with female gonophores, labelled “ type ”; reconstituted from dry, 60% IPA. BCPM 976-00228-002: Japan , Sagami Bay, Eboshi-iwa, 19 April 1931 , several colony fragments, in rather poor condition, some with female gonophores; reconstituted from dry, 60% IPA. Type locality. Japan : “ Eboshi-iwa , near Enoshima , at tide mark” ( Fraser 1935b ). Current status. Valid. Remarks. Specimens listed above as syntypes , from collections made by Emperor Hirohito in Sagami Bay, Japan , were sent to Fraser (1935b) for identification. No name-bearing type designation was made by him in the original account of the species. Notwithstanding the label marked “ type ” in one of the samples (BCPM 976-00228- 001), both collections are taken here to contain syntype material (see ICZN Art. 72.4.7). Hydroids in the two bottles have been dry at some time in the past, and we consider all of them to be unsatisfactory for lectotype designation. A sample of Eudendrium biseriale in the Emperor Shōwa Hydroid Collection at NMNS (NSMT-HyR 971, Japan , Sagami Bay, Eboshiiwa, off Chigasaki, 19 April 1931 ) seems to correspond with collection data accompanying specimens in the RBCM, but we do not know if Fraser examined it in describing the species. It has not been included here as a syntype . Hydroids of E. biseriale were subsequently re-described by Yamada (1954) and Hirohito (1988) . Both authors noted that male gonophores are usually scattered rather than being arranged in two whorls, as emphasized by Fraser (1935b) and as implied by the specific name he applied to it.
