Probolitrema tomalis sp. nov. (Trematoda) from Dasyatis dipterura and Brachylaemus virginianus (Dickerson) (Trematoda) from Didelphys virginiana
<p>The genus Probolitrema was established by Looss (1901) in recognition of the location of vitellaria and multiple testes entirely outside the extra caecal field in Anaporrhutum richardii Lopez (1888) which differentiated it from A.albidum Ofenheim (1900) with the vitellaria within and the testes …

Taxonomic studies on the genus Podocotyle (Trematoda: opecoelidae)
The original intent of this study was to reinvestigate and confirm the validity of thirteen species of Podocotyle reported from Dillon Beach, California. Eight species were described by Park (1937) and five described by Johnson (1949-unpublished). Among these species basic similarities were evident …

Studies on the biology of Plagiorchis elegans (Rudolphi, 1802), (Trematoda: Digenea) in its mammalian and molluscan hosts
The taxonomy of the genus Plagiorchis Luhe, 1899 is reviewed with particular reference to the species P.elegans (Rud. 1802) and a list of Plagiorchia species previously recorded in Britain is given. The life cycle was initially established using Lymnaea stagnalis, Chironomus sp.larvae and LACA …
