Some Chondracanthidae (Copepoda) from Fishes of British Columbia

Abstract

This paper redescribes three species of Chondracanthidae (Copepoda) parasitic on the fishes of British Columbia and previously recorded by earlier writers (Chondracanthus irregularis, Ch. pinguis, and Ch. gracilis). Two new species are described (Ch. pusillus and Acanthochoniria holocephalarum). Finer structural details of the chondracanthid appendages are illustrated and the taxonomic status of the previously known species is discussed.
