title: Studies on the fresh water cercariae in Leyte Island, Philippines. 6. Cercariae from Lymnaeidae and Bulinidae.
abstract: In the previous paper of this series, the cercariae from Oncomelania quadrasi (Part 2), from the snails of Thiaridae (Part 3), from the snails of Viviparidae and Pilidae (Part 4), and from Planorbidae (Part 5) were reported continuously. In this paper the crecariae from Lymnaeidae and Bulinidae were dealt with. These studies were all carried on during the period of 1975 and 1976 in Leyte Island, Philippines. From the lymnaeid snails seven species of cercariae, comprising two echinostome cercariae, one fasciolid cercaria, and four xiphidiocercariae were detected. From the bulinid snails, only two xiphidiocercariae were found, both of which were identifiable with those from the lymnaeid snails. These seven species of cercariae are described and illustrated with a tentative name from Cercaria leyteensis no. 37 to Cercaria leyteensis no. 43, in addition with some remarks on their presumptive life histories.
