Lectotype, by present designation. RBCM 976-00948-003: Canada, British Columbia, Queen Charlotte Islands (= Haida Gwaii), Moresby Island , Kaison Bank , 201 m, 28 July 1936, one colony, 3.3 cm high, with one gonotheca, in good condition; 70% ethanol. 

Paralectotypes. BCPMAbout BCPM 976-00948-001: Canada, British Columbia, Queen Charlotte Islands (=Haida Gwaii), Moresby Island, Kaison Bank, 201 m, 28 July 1936, one colony, 2.1 cm high, without gonothecae, in fair condition; labelled " type "; 60% IPAAbout IPA.

BCPM 976-00948-002: Canada, British Columbia, Queen Charlotte Islands (= Haida Gwaii), Moresby Island , Kaison Bank , 28 July 1936, one colony, 1.3 cm high, with one gonotheca, in good condition; slide. 

Type locality. Canada, British Columbia: Queen Charlotte Islands (= Haida Gwaii), west coast of Moresby Island , Kaison Bank ( Fraser 1937a). 

Current status. Valid, as Astrolabia furcata ( Fraser, 1937a)  .

Remarks. Although Fraser (1937a) designated no name-bearing type for Tetranema furcata  , syntype material of the species exists at the RBCMAbout RBCM. Two colonies were represented in fluid ( BCPMAbout BCPM 976-00948-001), with the larger one, in better condition and with a gonotheca, being designated here as the lectotype of the species. It was removed to a new bottle and assigned a new catalogue number ( RBCMAbout RBCM 976-00948-003). The smaller colony, sterile and in poorer condition, was returned to the original bottle as a paralectotype ( BCPMAbout BCPM 976-00948-001). A second paralectotype specimen occurs on a microscope slide ( BCPMAbout BCPM 976-00948-002). Although the slide is broken lateral to the mount, the hydroid colony is in good condition and bears a gonotheca.
