ResumoIn the summer of 1949, Harold C. Hanson of the Illinois State Natural History Survey took part in the Perry Expedition which was carried out under the auspices of the Arctic Institute of North America with funds furnished by the Office of Naval Research. The Perry River opens onto Queen Maud Gulf in the Arctic Ocean close to the dividing line between the districts of Mackenzie and Keewatin in the Canadian Northwest Territories, at approximately 102? W. longitude and 680 N. latitude. During this trip Mr. Hanson collected fecal samples or intestinal contents from 49 wild birds of 21 species. The results of the study of this material are presented herein. In order to determine the taxonomic position of the coccidia found in these birds, a critical review of the literature was found necessary. Many species have been described since Becker's (1934) book and Boughton and Volk's (1938) review. While Hardcastle's (1943) checklist includes many of these, it does not give morphological data, nor does it give the presently accepted scientific names of the hosts. Furthermore, since many workers named new species without adequate reference to previous or contemporary work, the validity of some species may be open to question. Finally, it is hoped that a summary of the data on morphology and host-parasite relationships may serve as a starting-point for and guide to future work. All bird names in this paper have been checked with the American Ornithologists' Union Check-list of North American birds (1931 and subsequent supplements) or with Peters' (1931-1948) Check-list of the birds of the world. I should like to thank Dr. Harvey I. Fisher, Department of Zoology, University of Illinois, and Dr. Ernst Mayr, American Museum of Natural History, New York, for information on certain points of nomenclature. Since all of the expedition's supplies had to be flown in, weight and bulk were important factors in determining the collecting methods used for fecal material. Most of the fecal samples were threefore collected in 15-25 nmI. screwcap vials. Before the vials were packed for the trip a line was marked on them to indicate 3/4 of their capacity.
