Observations on the Genus Echinococcus Rudolphi, 1801

Abstract

Tænia echinococcus has always been recognised as one of the most important tapeworms of carnivores, both from the human and the economic point of view. Its intermediate stage, or Hydatid, assumes many forms, but most modern workers believe that all these forms—with one possible exception, the alveolar form from Central Europe—are merely the manifestations of a single species.
