Abstract

A key is presented for the identification of the species of North American freshwater triclads or planarians known at present. Introductory chapters deal with the collecting, culturing, preservation, study, and general organization and life cycle of planarians. The key is followed by a listing of the species and subspecies, giving their distinguishing characteristics, ecological requirements, and geographical ranges. Illustrations depict the external appearance and diagrams of the reproductive organs of the individual taxa. The principal literature for each species is indicated and listed in the appended bibliography of 65 items. An index of the generic and specific names and synonyms concludes the report. One new subspecies, Polycelis coronata brevipenis is established for L. H. Hyman's Polycelis coronata.
