Remarks. No collections of Cryptolaria triserialis Fraser, 1913b, type or otherwise, could be located during this study. The species was not mentioned as part of the Fraser Hydroid Collection by Arai (1977), and it was not found by us during this study in either the online database, or the collections, or a museum catalogue of the collection.

Cairns et al. (2002) followed Fraser (1944a) in assigning the species to Acryptolaria Norman, 1875, as A. triserialis . However, Kramp (1932) included C. triserialis in the synonymy of Grammaria borealis (Levinsen, 1893), a conclusion adopted by Vervoort (1972), Schuchert (2001a), Antsulevich (2015), and WoRMS.
