Abstract

An account and description are given of Salmincola salvelini sp. nov., a parasitic copepod (Lernaeopodidae) infesting the speckled trout (Salvelinus fontinatis Mitchill) at Gaspé, P.Q., and also taken from arctic charr (Salvelinus alpinus) collected at Sugluk Bay, northern Labrador. S. salvelini is found in the mouth of both hosts where it is firmly attached to the tissues of the roof and sides of the mouth and tongue. It does not occur on the gills, and in this respect is distinct from Salmincola edwardsii commonly found on speckled trout in North America. S. salvelini has a marked superficial similarity to S. gibber, from which it can be distinguished by the presence of a spine on the terminal segment and a papilla on the penultimate segment of the maxillipeds.
