On a New Species of the Nematode Genus Oswaldocruzia from the Newt

The following description of a new species of the genus Oswaldocruzia is based on the examination of a considerable number of specimens collected from the intestines of 80 newts caught at Aberystwyth. They were found to be equally common in the Smooth Newt ( Molge vulgaris Linn.) and the Palmate Newt ( Molge palmata Dum. and Bibr.).
