Hydractinia laevispina Fraser, 1922a: 97 , pl. 1, figs. 1–6.

Syntypes. BCPM 976-00220-001 : Canada, British Columbia, Gabriola Passage , 29 June 1921, 18 m; dry.

Type locality. Canada, British Columbia: Gabriola Pass , western end ( Fraser 1922a).

Current status. Valid.

Remarks. Collection data accompanying material in the Fraser Hydroid Collection at the RBCM (BCPM 976- 00220-001) accord with those given in the original description of Hydractinia laevispina by Fraser (1922a). In the absence of a type designation of the species by Fraser (1922a), those specimens are syntypes. We have not designated a lectotype from the available material because it is now dry and in very poor condition.

Both male and female colonies of the species, found growing on shells of a barnacle (“ Balanus aquilla ” = Menesiniella aquila ), were observed and described in Fraser’s (1922a) original account. Hydractinia laevispina is considered a valid species (Brinckmann-Voss 1996; Cairns et al. 2002; Mills et al. 2007; Miglietta et al. 2009).
