Studies on larval digenetic trematodes of xiphidiocercariae from some Egyptian fresh water snails.

Six xiphidiocercariae are described from seven Egyptian snails, includes Cleopatra bulimoides, Malanoides tuberculata, Lymnaea cailliaudi, Bulinus truncatus, Biomphlaria alexandrina and Lanistes carinatus collected from Giza (Abou Rawash) and Qualiobyia (Qualiuob). Details are presented on the morphology, behavior of the cercariae, as well as other larval stages within the snails, with discussion and comparison between the previously described cercariae.
