Abstract
The life cycle of Echinoparyphium dunni, a new 43-spined species is described. The first intermediate host is the freshwater snail, Lymnaea rubiginosa (Michelin). The same and other freshwater snails such as Gyraulus convexiusculus (Hutton), Indoplanorbis exustus (Deshayes), and Bellamya ingallsiana (Lea) serve as second intermediate hosts. Adult worms have been obtained under experimental conditions from pigeons; ducklings; black-headed or chestnut munias, Lonchura ferruginosa (Sparrman); spotted munias, Lonchura punctulata (Linnaeus); and Java sparrows, Padda oryzivora (Linnaeus); but not from rats, mice, and hamsters.
