A SYSTEMATIC REVIEW OF THE GREAT BASIN REPTILES IN THE COLLECTIONS OF BRIGHAM YOUNC; UNIVERSITY AND THE UNIVERSriY OF UTAH Wilmer W. Tanner and Benjamin H. Banta' Introduction This report is one of a planned series of analyses of reptile speci-mens taken from the Great Basin and now deposited in the major institutional repositories of the western United States. We hope and anticipate that such reports will provide a more adequate systematic and distributional picture of the Great Basin reptile fauna. At present we are concerned mainly with the species occurring in this region and specimen locality data If such can be completed we would then perhaps have a nearly complete list of species and subspecies occurring in the basin as well as the distribution limits of each. The general physical environment and historical aspects of the Great Basin have been treated in recent works by Banta (1963a) and Banta and Tanner (1964). The general physical delimitation of the Great Basin in this account is based largely upon the 1953 edition of the map "Water Resources Development of the United States." by the United States Geological Survey. We have made one correction in southern Nevada and perhaps other minor details should be adjusted. However, we find the map to be useful and generally ac-curate even in most details. Figure 1 illustrates the physical defini-tion of the Great Basin in addition to the political subdivisions of and within the area as used herein. The following is a check list of the counties of the states making up the (jreat Basin. An asterisk ( * ) preceding a county name indi-cates that this particular county is located on the border and is thus not located in its entirety within the Great Basin. 1 Portion^ of this study were supported by a grant-in-aid from the Society of the Sigma Xi and the Research Society of .ierira (19f>2) and a faiully travel grant from Colorado College, Colorado Springs. Publication was made possible by a grant-in-aid from the Society of the Sigma Xi and the Research Society of America (1963).
