Ten of these plerocercoids were taken from nine fish during the examination of a lot of forty-one wall-eyes, Stizostedeon vitreum Mitch., sent to me from Lesser Slave Lake. Three plerocercoids of the same species were found in three of twenty-five wall-eyes from Lake Manitoba. One plerocercoid of the same species was found in a single fish in the examination of a lot of twenty-three wall-eyes from Lac la Biche (Alberta) and one plerocercoid was found in one of fifteen pickerel, Esox lucius L., from Lake of the Woods.
