Remarks.—Scalopus aquaticus reaches the western limits of its range in eastern Colorado and southeastern Wyoming; specimens from this area are, on the average, smaller and paler in color than those from anywhere else in the range of the species. Jones (1964:75) noted that the pale color of S. a. caryi generally is consistent throughout the range of the sub- species in Nebraska, but that specimens from the western part of the state are smaller in size than those from the vicinity of the type locality in Antelope County. Coloradan speci- mens agree in cranial dimensions with speci- mens reported by Jones (op. ) from Dundy County, Nebraska. Maximum external measurements of Coloradan specimens re- ported herein are misleadingly large; the values were converted to millimeters from original data recorded in inches and hun- dredths of inches. Records of occurrence.—Specimens examined, 15, distributed as follows: LOGAN COUNTY: sec. 34, T. 9 N, R. 50 W, 1 (CSU); Merino, 2 (CSU). WASHINGTON COUNTY: Eastern Colorado Range Experiment Station, 14 mi. N Akron, 1 (UU). YUMA COUNTY: Dry Willow, 4 (DMNH); Wray, 7 (6 DMNH, 1USNM). Additional records: MORGAN COUNTY: no precise locality (Lechleitner, 1969:35). SEDGWICK COUNTY: near Julesburg (Burnett, 1924a:264).
