Of sixty-four bobcats, Lynx rufus rufus, collected in Virginia end North Carolina, twenty-five percent were found to be infected with an unidentified lungworm. As the literature showed no record of lungworm parasites from Lynx rufus rufus, a study was made of the lungworms of the cat family, Felidae. A new metastrongylid genus and species is here described, named and classified. The name is designated as Lynxrufus wilsoni. Lynxrufus wilsoni is placed tentatively in the subfamily Skrjabingylinae due to the similarity of its male reproductive organs to the male reproductive organs of the other members of that subfamily. / Ph.
