Description
Hydractinia laevispina Fraser, 1922a
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).
