Abstract

Although cestodes of the genus Echinococcus have been much studied in the past, there is need for an evaluation of these morphological characters used as the basis for species differentiation. The generous cooperation of other investigators in providing necessary foreign material and the results of nearly five years of field work in Alaska make possible such a study. It is the purpose of the paper to evaluate morphological characters used at the species level to differentiate these cestodes, and to review the status of species currently considered valid.
