ANOTHER EXTENSION TO THE RANGE OF Xantusia arizonae.-On May 28, 1939, Charles Shaw succeeded in securing a specimen of this form at Valentine, Mohave County, Arizona, thus extending the range some 80 miles to the northwest. X. arizonae now has a total range, diagonally across central Arizona, of nearly 200 miles (see COPEIA, 1938: 193). On a trip last year, past Valentine and Hackberry, some likely looking rocks had induced the resolve to return for a Xantusia hunt at the earliest opportunity, and the new record is the result. The rocks, however, were found too hard to flake easily and therefore our efforts produced only one specimen. It is my opinion that X. arizonae will eventually be found to have a considerably greater range than is now known, since suitable rocky areas are widespread through Arizona. However, only where the boulders exfoliate in weathering is capture simplified; elsewhere the lizards can seek diurnal refuge in crevices from which they cannot be extricated, or even their presence demonstrated.
