Abstract

Summary

A description is given of the structure and activity of two new cercariae of peculiar type captured free in Lake Erie and Lake St. Clair. They are designated Cercaria anchoroides nov. spec. and C. gorgonocephala nov. spec., and are compared with known European species. Although such an occurrence must be common, these forms are the first to be taken in open fresh waters.
