Resumo1. Six new furcocercous cercariae from the north-western United States are described and comparisons with similar forms are made. 2. On the basis of the structure of Cercaria tuckerensis spec. nov. and three cercariae reported in the recent literature it is possible to characterise more precisely the Elvae group, which now contains eight members. 3. The execretory system of Cercaria elvae Miller, 1923, was re-studied and found to differ from the original description. The bearing of this sort of error on Faust's use of excretory system formulae is touched upon. 4. Cercaria burti Miller, 1923, originally described from northern Michigan, is reported from San Juan Island. 5. Certain features of the morphology and biology of the furcocercous cercariae are discussed in the light of this and other recent studies. 6. Check List II of the furcocercous cercariae, with eighteen larvae, is given.
