Hydractinia armata Fraser, 1940b: 39  , figs. 1a–f.

Syntypes. BCPM 976-00213-001: USA, California, San Mateo County, Montara , 8 June 1939, coll. T. Bullock and R  . Fernald; 60% IPA.

BCPM 976-00214-001: USA, California, San Mateo County, Pillar Point , 15 June 1939, under ledge, coll. T. Bullock  ; 60% IPA.

Lectotype, by present designation. RBCM 976-00213-002: USA, California, San Mateo County, Montara , in tidepools, on coralline algae, 8 June 1939, one colony, with gonophores, in fairly good condition, coll. T. Bullock and R. Fernald; 70% ethanol. 

Paralectotypes. BCPMAbout BCPM 976-00213-001: USA, California, San Mateo County, Montara, in tidepools, 8 June 1939, coll. T. Bullock & R. Fernald, two fragments, with gonophores, in fair condition; 60% IPAAbout IPA.

BCPM 976-00214-001: USA, California, San Mateo County, Pillar Point , 15 June 1939, intertidal ledge ( Fraser 1940b), in poor condition, coll. T. Bullock  ; 60% IPA.

Type locality. USA, California: San Mateo County, Montara (misspelled as Mantara ), encrusting corallines in tidepools ( Fraser 1940b). 

Current status. Valid.

Remarks. In establishing Hydractinia armata, Fraser (1940b)  failed to designate name-bearing types. Specimens located at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00213-001; BCPMAbout BCPM 976-00214-001) during this study, from the two original type localities near Moss Beach, California, are considered syntypes here. We designate the best of the available syntype colonies as the lectotype herewith ( RBCMAbout RBCM 976-00213-002).

Hydractinia armata  , taken to be valid ( Cairns et al. 2002; Mills et al. 2007; WoRMS), has been reported southwards to San Nicolas Island, California ( Fraser 1948), and northwards to a tidepool at Race Rocks, British Columbia, in the Strait of Juan de Fuca (Brinckmann-Voss 1996). Its spines, very numerous, are noteworthy in being long, smooth, and nearly cylindrical up to a tapered point, with a series of internal annular thickenings ( Fraser 1940b).
