In describing Meganema claviformis , Fraser (1939b) reported that the hydroid was “attached to sponges, barnacle shells, etc.” No name-bearing type was designated by him. The only type material of the species in existence is mounted on a slide (BCPM 976-00302-001) in the Fraser Hydroid Collection at the RBCM. Two specimens occur on the slide, both of them fragmentary. While the fragments may be part of a single colony, we have not assumed so for nomenclatural purposes (ICZN Recommendation 73F). The specimen on the left side of the slide has been designated here as the lectotype (RBCM 976-00302-002) to objectively define the species and ensure stability of nomenclature. The specimen ...
