Abstract
THE most difficult group of helminth parasites to deal with from the morphological point of view is the Cestoda. They have superficially a very considerable resemblance to each other and an elaborate technique is necessary before their internal anatomy can be satisfactorily studied. The older naturalists in their classifications based their systems largely on the external characters—characters which in a colourless animal such as a tapeworm are unsatisfactory, and are rendered even more unsatisfactory by the extremely muscular nature of the parasite and the absence of any supporting skeleton to retain a permanent shape. Moreover, the complicated life-cycle of these animals has made confusion worse confounded and our knowledge of the whole group is in a very chaotic condition indeed.
