EXTERNAL PAEASITES 209 (Ooniocotes Jiologaster), the large hen louse (Goniocotes abdomi- 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 Docophorus icterodes and lApewnis temporalis are com- mon; on geese a variety of D. icterodes; on pigeons the slender pigeon louse (Lipeurus hacvius) and the broad pigeon louse (Goni-^ ocotes compar) cause most of the harm from lice. Neumann lists 6 species as occurring on the pheasant as follows: Lipeurus variabilis, Goniodes colcTiicus, G. truncatus, Goniocotes chrysocephalus, Menopon productum^ and M. hiseriatum; on the pea- fowl, Goniodes falcicomis, G. parviceps, Goniocotes rectangidatus and Menopon phwostomum; 8n the guinea-fowl, Lipeuirus numidw, Goniodes nwmidianus, Goniocotes rectangulatus, Menopon numidce and Lipevr rus variabile of the fowl. In addition to the two species listed by Bishopp and Wood as important lice on the pigeon in the United States, Neumann mentions Goniodes minor, ^ ââ â , , , , ^ ,' . __ . , ,/ Kg. 39.

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- s
