The life-cycle of Echinostoma trivolvis (Cort, 1914) has been completed experimentally and the validity and identity of this species are discussed. Synonyms for cercariae and adults of E. trivolvis are as follows: Cercaria trivolvis Cort, 1914, C. trisolenata Faust, 1917, C. acanthostoma Faust, 1918, C. complexa Faust, 1919; Distoma echinatum Zeder, 1803, of Leidy (1888, 1904) and Hassall (1896); E. echinatum (Zeder, 1803) of Hassall (1896), Stiles & Hassall (1895), Barker & Laughlin (1911), Barker (1916) and Swales (1933); E. revolutum (Frölich, 1802) Dietz, 1909 of Johnson (1920), Fallis (1934), Beaver (1937) and Fried & co-workers (1968–1989); E. armigerum Barker & Irvine, 1915; E. coalitum Barker & Beaver, 1915; E. callawayensis Barker & Noll, 1915; E. paraulum Dietz, 1909 of Miller (1937); E. multispinosum Vigueras, 1944; and Echinoparyphium contiguum Barker & Bastron, 1915. The first intermediate host is the planorbid snail Helisoma trivolvis. Second intermediate hosts are various pulmonate and prosobranch snails, mussels, planarians, fishes, frogs, tadpoles and freshwater turtles. Final hosts are various birds and mammals. E. trivolvis occurs only in North America.
