One species of Apharyngeal Brevifurcate Distome Cercariae was obtained by the author from fresh water snails, Semisulcospira libertina (could) in Shizuoka Prefecture. This. furcocercous cercaria was identifiable with that reported by Yoshida (1917) who obtained it from the same species of snail in Tokushima Prefecture. A tentative name “Cercaria G” had been given for this cercaria by Yoshida, and then it renamed as Cercaria scripta by Faust (1924) .
According to my present experiment this cercaria proved to be infective for the chicken of Gallus gallus domesticus by the injection method, and a number of worms were discovered from their mesenteric vessels. The worms apparently belonged to the genus. Pseudobilharziella Ejsmont, 1929, and were identifiable with P. corvi Yamaguti, 1941. The detailed morphology and life cycle of this species are presented in the present paper.
