THE OCCURRENCE OF CONTRACAECUM TRAVASSOSI (NEMATODA)
IN NORTH AMERICA
Seven specimens of a nematode (5 males and 2 females) of the genus Contracaecum were
collected from the ventriculus of Pandion haliaetu.r carolinensis (Gmelin) (osprey) captured at
Greenville, Ohio. After a comparison with C. travassosi described by Gutierrez (1943. Sobre
la morfologia de una nueva especie de "Contracaecum" (Nematoda: Ascaroidea). Rev. Brasil.
