Extract

Some time ago, in a short article on maturation in the liver fluke Fasciola hepatica (L.), Sanderson (1953) suggested that development might be gynogenetic on the grounds that she was unable to find any second maturation division nor any polar bodies. Nevertheless, the presence of two large “pronuclei” seemed to point to normal zygogenesis. Unable to come to any definite conclusion the author decided to investigate maturation in another digenetic trematode, Haplometra cylindracea (Zeder 1800) when ample supplies came to hand from class dissections of frogs.
