Hydractinia carolinae Fraser, 1912c: 351  , figs. 9Α–C.

Syntypes. BCPMAbout BCPM 976-00215-001: USA, North Carolina, off Beaufort, 14–15 May 1911, dredged by R/V Fish Hawk, on legs of crab; 60% IPAAbout IPA.

Lectotype, by present designation. RBCM 976-00215-003: USA, North Carolina, about 37 km SW of Beaufort , depth 24–26 m, 14–15 May 1911, on leg of crab, dredge, R/ V Fish Hawk, one colony, in fair condition, with gonophores; 70% ethanol. 

Paralectotypes. BCPMAbout BCPM 976-00215-001: USA, North Carolina, off Beaufort, 14–15 May 1911, dredge, R/V Fish Hawk, several colonies or colony parts on legs of crab, some with gonophores; 60% IPAAbout IPA.

BCPM 976-00215-002: USA, North Carolina, one colony or colony part, Beaufort ; slide. 

Type locality. USA, North Carolina: about 37 km SW of Beaufort , depth 24–26 m, on a crab ( Fraser 1912c). 

Current status. Valid.

Remarks. According to Fraser (1912c), Hydractinia carolinae  was described from hydroids occurring on the legs of a single crab, and all were female. Materials at the RBCMAbout RBCM listed above ( BCPMAbout BCPM 976-00215-001; BCPMAbout BCPM 976-00215-002) represent the original collection and constitute syntypes because the species was found in the type locality only once ( Fraser 1944a). Indeed, all specimens may have originated from a single colony and represent parts of a holotype by monotypy ( ICZN Art. 73.1.2). However, we have considered the fragments, on different legs, as syntypes and have designated a lectotype from one of them ( ICZN Recommendation 73F). The best colony, or colony fragment, from BCPMAbout BCPM 976-00215-001, has been selected as the lectotype ( RBCMAbout RBCM 976-00215-003). Other material assigned to the species in the Fraser Hydroid Collection at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00216-001, Puerto Rico, Culebra, 25 February 1934, 8-10 fm) (Arai 1977) is not part of the type series.

Hydractinia carolinae  is held to be valid ( Cairns et al. 2002; WoRMS).
