BCPM 976-00454-002: Canada, Nunavut, Dease Strait, 40 fm ( 73 m), 25 July 1937, RCMP Vessel St.Roch, dredge, one colony fragment, attached to hydrocaulus of a sertulariid, 3 mmhigh, in good condition, without gonophores, coll.

Typelocality. Canada, Nunavut: Dease Strait, 68°58’N, 106°20’W, 40 fm ( 73 m) ( Fraser 1939b). Current status.Valid, but see Remarks below.
Remarks.In the absence of a typedesignation of Bonneviella gracilisby Fraser (1939b), a name-bearing typehas been selected from syntypematerial of the species in the Fraser Hydroid Collection at the RBCM (BCPM 976- 00454-001; BCPM 976-00454-002). The two samples are part of the same collection, obtained by Sgt. H.A. Larsen aboard the Royal Canadian Mounted Police vessel St. Rochwhile stuck in the ice in Dease Strait, Nunavut, Canada( Fraser 1939b). The best of the available specimens, designated here as the lectotype, is one of two colony fragments on a microscope slide (BCPM 976-00454-002). Occurring on the right side of the slide, it is attached to the stolon of another hydroid species. This specimen (RBCM 976-00454-003) consists of a hydrotheca with a largely intact hydranth, together with a hydrothecal pedicel and part of a stolon. The other colony fragment of B. gracilis, attached to a sertulariid on the same slide, is a paralectotype(BCPM 976-00454-002). While also in good condition overall, its hydranth is more deteriorated than that of the lectotype. Additional paralectotypesare fragments of the species in fluid preservative (BCPM 976-00454-001). Although labelled “ type”, they are now in unsatisfactory condition. Noother typematerial is known to exist. Fraser (1939b)described this species from sterile specimens overgrowing colonies of a hydroid identified by him as Thuiaria similis( Sertularia similis Clark, 1877). Although currently accepted as valid in WoRMS, studies are needed to confirm the identity of Fraser’s Bonneviella gracilisat the ranks of family, genus, and species.
