discussion
Remarks. Fraser (1914 a) described Thuiaria distans without designating a type. Nevertheless, a hydroid colony from the type locality in the Fraser Hydroid Collection at the RBCM (BCPM 976 - 00708 - 001), listed above, is certain to be a type specimen. Given that Fraser was not explicit in stating the number of colonies in hand as the species was being described, however, we avoid assuming that the specimen is the holotype by monotypy and designate it as the lectotype (ICZN Recommendation 73 F). The printed catalogue of the Fraser Collection indicates that the specimen was dry at some point but was rehydrated in January 1984. For all that, it is still in fair condition. Other specimens of the species occur in the Fraser Hydroid Collection at the RBCM (BCPM 976 - 00709 - 001: Northwest Bay, 19 June 1914; BCPM 976 - 00709 - 002 and BCPM 976 - 00709 - 003: Northwest Bay; BCPM 976 - 00710 - 001: 14 km S of Marble Island, 26 June 1935, 347 m), but they are not part of the type series.
