The Trematode Parasites of North Queensland. I

Abstract

It is only within the last half-dozen years that any serious attempt has been made to deal systematically with the parasitic worms of Australia. In 1909 Dr T. Harvey Johnston commenced what has proved to be a most extensive and successful survey of the cestode parasites. Dealing at first chiefly with Southern forms, he has latterly (1912) continued his investigations in Queensland and has extended them to include Nematodes and Echinorhynchs. Some years previously (1901) Dr S. J. Johnston of Sydney had started a study of the Trematode parasites, but this did not lead to any outstanding results until last year, when his important paper on the Trematode parasites of Australian frogs appeared. He has followed this up by another important work on Trematodes from North Queensland, which has appeared during the present year.
