Upon studying the tapeworms of cattle and sheep we became con- vinced that Moniezia expansa contained more than one species, and diagnosing the proper M. expansa by a few segments and the scolex of Rudolphi’s original material, we separated from it Moniezia planissima. Stiles found this species at Paris, and Hassall and Stiles found it at Washington, D. C. We have also found several segments of this worm in the material collected by Hr. Curtice, under the label u Tcenia expansa,” and Dr. Norgaard has recently found it in Virginia. Two of the best known medical zoologists of France (Railliet and Neumann) have also sent us specimens of this species under the label “ Tcenia expansa The only publications on this worm, as a distinct species, are the short preliminary notes by Stiles (1,2). The present account of the anatomy is the paper anticipated by those preliminary iiapers.
