On Three Known Trematodes from African Birds, with Notes on the GeneraTyphlocoelum, ParyphostomumandPetasiger

Abstract

In the Summer of 1943 Dr. P. L. leRoux, to whom I am very grateful for the material, madea collection of worm parasites of ducks and waterbirds, shot near the Kalunga River, Chunga Farm, Chinsali District, Northern Rhodesia. Three genera of Trematodes are represented in this material, two of which, as far as records show,viz. TyphlocoelumandParyphostomum, whose members are widely distributed in Asia, Europe and America, are here recorded for the first time from the African Continent.Petasiger variospinosusis recorded from a new host and a new locality.
