Studies on the biology of Notocotylus attenuatus in the domestic fowl were undertaken with the aim of determining where in the alimentary system the metacercariae excyst and how soon the juvenile worms become established in the caecum of the host. The metacercariae were found to excyst in the lower intestine and juvenile worms were recovered from the caecum after 4 h. Thereafter, as the worms increased in size they changed their position relative to the viii and also moved down the caecum, coming to lie in the blind ending region as the worms approached maturity.
