Two nematodes, Acuaria anthuris (Rudolphi, 1819), Diplotriaena tricuspis (Fedtschenko, 1874); two cestodes, Anomotaenia constricta (Molin, 1858), Hymenolepis corvi (Mayhew, 1925); and one acanthocephalan, Mediorhynchus grandis (Van Cleave, 1916) were recovered from the white-necked raven (Corvus cryptoleucus Couch). All represent new host and distribution records. A relationship appears to exist between corvid host percentages and extent of zoogeographical distributions.
