Additional Records and Extensions of Known Ranges of Mammals from Utah

The Museum of Zoology, University of Utah, contains approximately 5000 specimens in addition to those available to Durrant (1952) when he prepared his account of the Mammals of Utah, Taxonomy and Distribution. Study of this material discloses two kinds of mammals not heretofore known to occur in Utah and extends the known limits of occurrence of many others as is set forth below in what may be thought of as a supplement to the aforementioned report of 1952.
