Kupriyanova assumed that further development of C. truncatus may take place either with an intermediate host or with an intermediate and a reservoir host. In the reservoir host (juveniles ofLeuciscus idus, , Abramis brama, Perca fluviatilis) the larvae settle in the intestine, usually in the anterior part; however, they apparently do not develop there.

The two thickenings form a chitinized ring. mm wide before the esophagus. Tridents strongly chitinized, mm long. Four well-developed sub- median papillae at the anterior end. Esophagus divided into a muscular anterior and a glandular posterior part. The muscular part of the esopha- gus was mm long and the glandular mm in one specimen. Three large nuclei present in the posterior part of the esophagus. Several large cells with distinct nuclei around the rectum. (83). FIGURE 42.
