摘要:
A trematode, widely distributed in Canada, and occurring in man and other fish-eating mammals, is described and its taxonomy discussed. Its life cycle has been worked out and it is shown to involve a snail,Amnicola limosa porataas first intermediate host and a fish, the common sucker (Catostomus commersonii) as the second intermediate host. The larval stages are described.
