Diseases of domesticated birds (1920) Diseases of domesticated birds diseasesofdomest00ward Year: 1920 EXTERNAL PARASITES 209 (Ooniocoies holocjaster), the large hen louse (Goniocotes ahdomi- nalis), the brown chicken louse (Goniodes dissimilis); on turkeys, the large turkey louse (Goniodes stylifer) and the slender tur- key louse (Lipeurus meleagridis). The common body louse and the shaft louse of chickens sometimes are found on the turkey. On ducks Docopfiorus icterodes and Lipeurus temporalis are com- mon; on geese a variety of D. icterodes; on pigeons the slender pigeon louse (Lipeurus haculus) and the broad pigeon louse (Goni- ocotes coynpar) cause most of the harm from lice. Keumann lists 6 species as occurring on the pheasant as follows: Lipeurus variabilis, Goniodes colcliicus, G. truncatus, Goniocotes chrysoceplialus, Menopon productum, and M. hiseriatum; on the pea- fowl, Goniodes falcicornis, G. parviceps, Goniocotes rectangulatus and Menopon phceostomum; on the guinea-fowl, Lipeurus numidce, Goniodes nwnidianus, Goniocotes rectayigulatus, Menopon numidce and Lipeu- rus variahile of the fowl. In addition to the two species listed by Bishopp and Wood as important lice on the pigeon in the United States, ISTeumann mentions Goniodes minor, G. damicomis, Menopon gigantemn, M. longicephaJum, Liotheum longicaudum and M. hiseriatum of fowls as occurring on pigeons; on geese, Lipeurus crassicomis, L. anseris, Trinoton anseris and T. lituratum; on ducks, L. anatis, T. luridum and Menopon ohscurum; on swans, Ornithonomus cygiii, Philopterus cygni and Trinoton anseris of the goose. The terms head louse, body louse, wing louse, etc., as applied to the lice of fowls indicate where the various species are found in greatest numbers and where their structure best adapts them to live. Thus the head louse exhibits a preference for the head but is occa- sionally found on the feathers of the wings. Some lice are adapted to live on the skin only, while others occur on the f
