Although only one of the samples listed above at the RBCM is marked “ type” (BCPM 976-00818-001), both are taken here to represent syntypematerial (see ICZN Art. 72.4.7) and are likely from the same collection. No name-bearing typewas designated by Fraser in the original account of the species, and none has subsequently been made to our knowledge. While Fraser labelled a fluid specimen (BCPM 976-00818-001) as the “ type”, it comprises fragments of one or more colonies, and is included here as a paralectotype. A single colony fragment apparently from the same sample on a microscope slide (BCPM 976-00818-002), in excellent condition and with gonothecae, is designated here as the lectotype.   Severaldozen records of  Antennella paucinoda, from Sagami Bay, Japan, also exist in the Emperor Shōwa Hydroid Collectionat the NMNS.  Threeof them are from the same locality as those at the RBCM(NSMT-HyR 147, NSMT-HyR 148, NSMT-HyR 149).  Hirohito (1995)noted the resemblance of  A. paucinodato several other species of  AntennellaAllman, 1877, but treated it as distinct. The validity of the species has been questioned in several subsequent works. Authors including Schuchert (1997)and Vervoort & Watson (2003)included it in the synonymy of  A. secundaria( Gmelin, 1791). In more recent accounts ( Schuchert 2015; WoRMS),  A. paucinodais listed as a synonym of  A. quadriaurita Ritchie, 1909, a species it more closely resembles in having two lateral nematothecae of unequal size on either side of each hydrotheca. Given the present irresolution of its relationships, together with its Japanese typelocality and the remote South Atlantic typelocality of  A. quadriaurita(Gough Island), we follow Hirohito in recognizing it as valid. The species is common in Sagami Bay ( Hirohito 1995). 1915526009 1931-08-04 BCPM Japan 75 Sagami Bay Arasaki 53 54 BCPM 976-00818-002 1 1915525995 1931-08-04 BCPM Japan 75 Sagami Bay Arasaki 53 54 BCPM 976-00818-002 1 lectotype 1915526004 [199,1027,1572,1597] Japan 75 Sagami Bay Hayama 53 54 1 holotype 1915525987 NMNS Japan Emperor Showa Hydroid Collection Several Sagami Bay 53 54 1 1915526027 RBCM Japan Emperor Showa Hydroid Collection Three Sagami Bay 53 54 1
