plain olive, the two dark stripes on each side of this being 

 nearly equal to each other and to their olive interspace. The 

 scales have no dusky edging behind in the light stripes." 



In a larger specimen "the upper dorsal dark line has dis- 

 appeared, leaving the lower quite distinct (separated from 

 its fellow by four rows of scales). All the dorsal scales are 

 margined behind with dusky. 



"All the other large specimens are entirely without lines. 

 All the scales edged behind with dusky." 



A series of specimens from the Huachuca Mountains, 

 Arizona, is before me. The young are bluish gray above, be- 

 coming olive gray on the head and bright blue on the tail. 

 Two whitish lines run back from the rostral plate across the 

 middle of the prefrontal plates, the outer edges of the 

 frontal, the middles of the frontoparietals, the edges of the 

 interparietal and parietal plates, and the inner part of the 

 occipital, behind which they unite to form a single, obscure, 

 median line on the anterior half of the neck. The super- 

 ciliaries and the outer portions of the supraoculars give 

 origin to a whitish line which is continued back across the 

 outer parts of the parietal and occipital plates and thence 

 back along the neck and anterior half of the body, gradu- 

 ally becoming less distinct. The upper labials are yellowish 

 white, except at their upper margins, and a whitish band 

 extends back from them, through the ear, along the neck 

 and body to the hind limb. A dark lateral stripe, about two 

 scales wide, bordered above and below by the two light lines 

 just described, extends from the nostril to the base of the 

 tail. The lower labials, chin, throat, chest, and limbs are 

 yellowish white. The other lower surfaces are bluish gray, 

 bluer on the tail. 



In larger specimens the upper labials have white centers 

 and dark upper and posterior edges, the supraoculars and the 

 parietal each have a white dot or spot on their outer portions,
