title: Studies on the life-cycle of Ganeo tigrinus Mehra & Negi, 1928 (Digenea).
abstract: The life-history stages of Ganeo tigrinus Mehra & Negi, 1928 infecting the Indian bull frog Hoplobatrachus tigerinus (Daudin) are described, those from cercaria to egg-producing adult having been established in the laboratory. Non-virgulate xiphidiocercariae are released by the planorbid snail Indoplanorbis exustus (Deshayes). Metacercariae occur in the haemocoel of dragonfly nymphs and become infective to the frog H. tigerinus within 15 days. The pre-patent period is 45 days. Growth and development of both metacercariae and adults are described in detail. Comments on the systematic position of Ganeo Klein, 1905 are included.
