The following report deals with the systematics and distribution of molluscs collected in and around certain lakes in Jasper National Park, Alberta, Canada. For the sake of completeness some records published by Baker (2) are also included. The investigations of which this forms a part were made under the direction of Professor Charles H. O'Donoghue at the request of the Biological Board of Canada, and I desire to thank him for his encouragement and help throughout.
