Studies on the fresh water cercariae in Leyte Island, Philippines. 4. Cercariae from Viviparidae and Pilidae.
During the period of 1975 and 1976, about two thousand snails of Viviparidae and two hundred snails of Pilidae were examined for cercarial fauna on Leyte Island, Philippines. From the snails of Viviparidae, 8 species of cercariae were found. These species consisted of two furcocercous cercariae, one monostome cercaria, three echinostome cercariae and two xiphidiocercariae. From the snails of Pilidae three species of cercariae were found; namely, one echinostome cercaria, one xiphidiocercaria, and one unknown cercaria. Among these species, one echinostome cercaria and one xiphidiocercaria were found to be common to snails of both families. In this paper these nine species of cercariae were described and illustrated with some remarks on their presumptive life cycles.
