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 RBCM (BCPM 976-00213-001; 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 (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 ).
