Resumo1. An account on the cercariae found in Melanopsis praemorsa common in the River Yarkon (Israel) is given. 2. A new species of Cercaria of the Pleurolophocerca group, Cercaria orospinosa , is described. 3. The development of C. orospinosa to the stage of metacercaria in the tadpole of Bufo viridis shows its affinity to the subfamily Cryptogoniminae (Hetero-phydae). 4. An artificial genus Velocercaria is proposed to comprise cercariae which have common morphology with Cercaria orospinosa and are characterized by the same type of tail-fins.
