Four females, three bearing eggs, taken from the gills, gill covers and base of the pectoral fins of a brown trout (Salmo trutta L.) captured in the Haupiri River near Kopara, Greymouth, South Island on 2 November 1963, and forwarded by the Chief Field Officer of the Wildlife Branch, Department of Internal Affairs to the Fisheries Laboratory, Marine Department, Wellington. The parasites were dissected out, and passed on to me by Mr. C. L. Hopkins of the Fisheries Laboratory who reports that the parasites had their heads and necks buried in the host tissue, causing a lession at the site of attachment.
