The objectives of this study were: (1) to make a detailed study of the distribution of the genus Parognathus in Utah; (2) to determine if any species or races not now recorded occur in the state; (3) to bring together notes on life histories of this genus, both from the literature and field studies; and (4) to determine habitat preferences of the species represented. This paper lists 14 subspecies belonging to 7 species of Perognathus occurring in Utah. One species is a new occurrence record, Perognathus fasciatus callistus, from northeastern Utah east of the Green River. The ranges of Perognathus longimembris, P. parvus, and P. formosus have been extended in Utah. Most of the pocket mice in Utah are found at an elevation of 6,000 feet or less. Perognathus parvus is the most widely distributed of any of the species and may be found at elevations as high as 10,000 feet. The other species appear to prefer special habitats. One group of P. parvus from the east slope of the Henry Mountains is believed to contain sufficient taxonomic traits to warrant separation into a new race. The reproductive cycle of the Utah species appears to be from April to July reaching its peak in June. There is little evidence that pocket mice have more than one litter per year. As a rule pocket mice are relatively free of ectoparasites. However, ticks, mites, lice, and fleas were taken from some of the Utah specimens.

Systematic ornithology has been woefully neglected in Utah. While this state has a number of men who know her birds and who have aroused interest in them, they have produced no published record of what we have. So far as the writer knows there is no adequate, representative, or systematic collection of Utah species within the state. Utah has, however, been fortunate in having a nuraber of expert ornithologists collect and study the bird life of different sections of bar territory.

The Uninta ground squirrel, Spermophilus armatus Kennicott, is the most abundant diurnal rodent in the Wasatch Mountains at the 7,000-9,000 foot level particularly in the campgrounds and picnic areas. Contact between man and the Uninta ground squirrel may be hazardous inasmuch as the causative agent of plague has been isolated from S. armatus and its flea parasites (Public Health Reports, 1937, 1938a, 1938b; Meyer, 1938; Byington, 1940; Allred, 1951; and Beck, 1955). Since these fleas are vectors of sylvatic plague and potential vectors of human plague, detailed knowledge about their population dynamics is desirable.

Fleas of the genus Foxella Wagner, commonly known as "gopher fleas," have various species of the mammal genus Thomomys Weid Neuweid in the Western United States as their hosts. Some workers maintain there are at least two species of fleas while others consider that all gopher fleas are of one species.
