For assistance in the field, we are especially grateful to the students
who were enrolled in the Field Course in Vertebrate Zoology at The
University of Kansas in the summers of 1961, 1965, and 1970, and to M.
A. Levy, R. R. Patterson, and T. H. Swearingen. In 1965 and 1970, the
summer field course was supported in part by grants (GE-7739 and
GZ-1512, respectively) from the National Science Foundation; Andersen
was supported in the field in 1968 by a grant from the Kansas City
Council for Higher Education. Personnel of the U.S. Forest Service
(Sioux Division, Custer National Forest), particularly District Ranger
Timothy S. Burns, were most helpful to us in the field, as were Wardens
Wesley Broer and Merritt Paukarbek of the South Dakota Department of
Game, Fish and Parks. Robert Kriege, Federal predator control agent
stationed in Buffalo, was most generous in sharing with us his knowledge
of rodents and carnivores in the area, and many present or former
residents, particularly Carl Cornell and Spike Jorgensen, also provided
useful information and were helpful in other ways.
Ectoparasites reported here were identified by Cluff E. Hopla (fleas),
Richard B. Loomis (chiggers), and Glen M. Kohls (ticks). Other than
mammals housed in the Museum of Natural History, we examined only three,
two in the U.S. National Museum (USNM) and one in the collection at
South Dakota State University, Brookings (SDSU).
