Transcript2079: A specimen of Distoma (Distoma clavatum) to show the two suctorious discs or cavities: of these the anterior alone is subservient to the imbibation of nutriment, the posterior and larger sucker being merely an organ of adhesion. A longitudinal section has been carried through it and the body posterior to it, showing that it is separated by an investment of muscular fibres from the parenchyma beneath. The membranous sac which occupies the clavate extremity of the worm is well displayed and a bristle is passed through its excretory outlet. Mounted with No. 416.
