les, with a median bluish white line which bifurcates on the 

 neck from one to sixteen millimeters behind the occipital 

 plates. There are two similar lines on each side; the first 

 originating on the superciliaries and with a distinct continua- 

 tion on the tail; the second starting at the nostril and ending 

 on the thigh. The ground color of the sides is largely 

 cinnamon or brick-red. The general tint of the tail is olive 

 brown above, pale blue below. The dark and light stripes 

 of the body are all continued along the tail for about half 

 its length. The back of the thigh is distinctly striped in all 

 specimens. The ventral and sublabial plates, the chin, gu- 

 lar region, and collar, are all pale blue or bluish white.

Distribution. — This lizard is known only from San Jose 

 Island, in the Gulf of California. 



Variation. — The supraoculars are 3-3 in 28 and 4-4 in 

 two specimens. The second supraocular is completely sepa- 

 rated from the median head plates by granules in none, 

 partly separated in eight specimens. The third is com- 

 pletely separated in two, partly separated in nineteen. The 

 scales on the collar are largest at its edge in one specimen, 

 smaller in thirty. The dorsal line in all specimens is single 

 with an anterior fork on the neck. This fork varies in 

 length from two to sixteen millimeters. 



Remarks. — This species differs from V. ccerulea in the
