Dr. Walker makes a signal contribution in gathering together all available information on the dragonflies of Canada and Alaska. The order as a whole and the zygoptera are covered. The treatment is not confined to taxonomy and geographical distribution, but includes data on habitats, seasons of adult life, and brief notes on habits when these are available.
