...romydis (Osborn). The writer collected Hoplopleura acanthopus from Microtus californicus at Calaveras Dam, Alameda County, California, and from M. pennsylvanicus at Ithaca, Tompkins County, New York. Elton,[Pg 142] Ford, Baker, and Gardner (1931) recorded this same species from M. argestis in England. Lice on the prairie vole are the same species as those found on other species of Microtus in other areas, but since Anoplura of the prairie vole do not parasitize the cotton rat, the white-footed mouse, and the deer mouse, this host specificity of lice makes it unlikely that lice would carry blood parasites from the prairie vole to any of the latter named rodents. Mites (Acarina except Ixodoidea) Many of the small mammals examined in this study had mites, some of which were collected and identified. Mites were collected from other species of voles in several localities in the United States and in one locality in Canada; as voles in widely separated regions are sometimes hosts to the same species of mites, these records will be presented here. The frequency of some kinds of mites in the identified material suggests that they are more abundant than other kinds. The occurrence of mites on small mammals from Lawrence, Kansas, is presented in table 7. The following comments can be made concerning the specificity and geographic ranges of several species of mites: Liponyssus occidentalis Ewing was found only on Cryptotis parva. Eulaelaps stabularis (Koch) was one of the more common kinds found on the prairie vole. This mite is rather large (about 1 mm. long) and is frequently (with the following species) seen running through the pelage of its host. In addition to the records for this species in table 1, it was found to be a common parasite on Pitymys pinetorum at Point Abino, Welland County, Ontario. Elton, Ford, Baker and Gardner (1931) found this same mite on Apodemus sylvaticus and Clethrionomys glareolus in England. A...
