Cladocarpus vancouverensis Fraser, 1914a

Cladocarpus vancouverensis Fraser, 1914a: 204 , pl. 35, figs. 132Α–D.

Syntypes. BCPM 976-00846-001 : Canada, British Columbia, N of Lasqueti Island , 19 June 1912, 27– 46 m ; 60% IPA.

BCPM 976-00847-001 : Canada, British Columbia, Northumberland Channel, near Dodd Narrows , 12 August 1912, 18– 37 m ; 60% IPA.

BCPM 976-00848-001 : near West Rocks , 17 October 1912, 15– 37 m ; 60% IPA.

Lectotype, by present designation. BCPM 976-00847-001: Canada, British Columbia, Northumberland Channel, near Dodd Narrows, 18–37 m, 12 August 1912, one colony with a broken hydrocaulus, total length ca. 12 cm high, with numerous gonophores, in fair but brittle condition; 60% IPA.

Paralectotypes. BCPM 976-00846-001 : Canada, British Columbia, N of Lasqueti Island , 19 June 1912, 27 – 46 m, several fragments of more than one colony, condition barely fair, brittle, without gonophores; 60% IPA.

BCPM 976-00848-001 : near West Rocks , 17 October 1912, 15 – 37 m, one colony, in poor condition, without gonophores; 60% IPA.

Type locality. Canada, British Columbia: Northumberland Channel, near Dodd Narrows , 18–37 m ( Fraser 1914a).

Current status. Valid.

Remarks. No name-bearing type was designated by Fraser (1914a) in establishing Cladocarpus vancouverensis , but syntypes of the species exist in the Fraser Hydroid Collection at the RBCM (BCPM 976- 00846-001, BCPM 976-00847-001, BCPM 976-00848-001). Of the syntype series, the largest and best colony (12 cm high, with gonophores) was collected in Northumberland Channel, BC (BCPM 976-00847-001) ( Fraser 1914a). That single specimen is designated here as the lectotype. The remaining hydroids of the original syntype series are paralectotypes (BCPM 976-00846-001, BCPM 976-00848-001). Other materials assigned to this species, at the NMNH (USNM 43755: 20 June 1901, no location data) and in the Fraser Hydroid Collection at the RBCM (BCPM 976-00849-001: Virago Sound, 30 July 1936, 110 m; BCPM 976-00850-001: off Masset Inlet, 30 July 1936, 82 m), do not form part of the type series.

Cladocarpus vancouverensis is considered a valid species ( Cairns et al. 2002; WoRMS). As noted by Fraser (1914a), the occurrence of this species in relatively shallow subtidal waters of the northeastern North Pacific is noteworthy, given the preponderance of congeners that occur in deeper waters and at lower latitudes. The species is reported to range from the Queen Charlotte Islands (=Haida Gwaii) southward to Baja California ( Fraser 1948; Hochberg & Ljubenkov 1998).
