Ectoparasites from birds in Newfoundland.

During an ongoing survey of the ectoparasites of birds in Canada (Bourgeois and Threlfall, 1981, Proc. Entomol. Soc. Wash. 83: 799-800; Eveleigh and Threlfall, 1974a, Proc. Entomol. Soc. Wash. 76: 270-277; Eveleigh and Threlfall, 1974b, Acarologia 16: 621-635; Eveleigh and Threlfall, 1975, Can. J. Zool. 53: 82-86; Eveleigh and Threlfall, 1976, Can. J. Zool. 54: 1694-171 1; Fitzpatrick and Threlfall, 1977, Can. J. Zool. 55: 1205-1209; Threlfall et al., 1979, Proc. Entomol. Soc. Wash. 81: 327-328) we acquired 75 frozen birds, of 46 species, from Newfoundland for examination. Each bird was identified and then examined under a dissecting microscope. Any parasites found were preserved in 70% ethanol and later mounted in Rubin’s solution (Rubin, 1951, Stain Technol. 26: 257-260) to facilitate identification. Voucher specimens of biting lice (Mallophaga) were prepared using 5% potassium hydroxide (55 C, 8-12 hr)/ lO% acetic acid/70/95/100% ethanol/xylene/ Canada balsam, while mites (Acarina) were cleared in lactophenol and mounted in Hoyer’s medium. One complete set of representative specimens has been deposited in the Canadian National Collection (Accession numbers 1985-39 to 1985-64; Biosystematics Research Institute, Ottawa, Ontario K 1 A OC6, Canada). Major taxonomic keys used to identify the parasites included Clay (1969, Bull. Br. Mus. (Nat. Hist.) Entomol. 24: 1-26), Keirans (1967, N.H. Agric. Exp. Sta., Durham,
