R. Zweifel Sept. 19, 1951 295 Cnemidophorus Tigris Cape, Kern Co., Calif. 1635 R. Zweifel A hatchling (51.36mm) captured when it tried to hide in a shallow hole by the river bank. Color pattern Four distinct yellow lines reach to the base of the tail. These are the paravertebral and dorso-lateral lines. The middorsal and dorso-lateral fields are black with a very few yellow spots appearing on the posterior half. The sides below the dorso-lateral line are black, spotted with yellow. The basal third of the tail is essentially a faded extension of the body pattern, which gradually alters to the bright blue of the distal two thirds of the tail. The chin and ventral body surface are white without distinct markings. Dec. 14, 1951 The lizard was kept alive until this date, when it was accidentally killed. S-V 42mm, tail 92.3mm. Some changes in color pattern had taken place. Faint indications of yellow spots are now visible as far forward as the fore leg insertion on the vertebral and left dorso-lateral fields.
