anterior nasal, first, second and third labials, loreal, pre- 

 frontal, and frontonasal plates. Loreal in contact with third 

 and fourth labials, first subocular, preocular, first supercili- 

 ary, prefrontal, posterior nasal, and sometimes first supra- 

 ocular, plates. Four supraoculars, first and fourth smaller 

 than others. Second, third and fourth supraoculars separ- 

 ated from superciliaries by small convex granules. Similar 

 granules intrude between third and fourth supraoculars and 

 frontoparietal and parietal. Occipitals represented by from 

 two to four transverse series of small plates behind parietals 

 and interparietal. About five superior and five or six in- 

 ferior labials to a point below middle of eye. Sublabials 

 large, the posterior separated from infralabials by small 

 plates. Anterior gulars largest centrally, becoming gradu- 

 ally smaller laterally and anteriorly, and changing rather 

 abruptly to smaller posterior gulars. Scales on center of 

 collar large, those on its edge largest. Small, smooth, con- 

 vex granules on back. Eight longitudinal rows of ventral 

 plates. Usually two or three large scutes, surrounded by 

 smaller plates and granules, in front of anus. Posterior 

 surface of forearm with a group of enlarged granules or 

 scales. Tail very long and provided with rings of large, 

 obliquely keeled scales. Femoral pores varying from 15 

 to 22. 



There is much variation in coloration, both individual 

 and with age. The color above, in adults, is reddish or 

 blackish brown with three narrow, light longitudinal stripes 

 along each side. These light stripes may be greenish, yel- 

 lowish or light reddish brown. The dark back ground be- 

 tween these light stripes usually is marked with one or two 

 series of small, rounded, light spots. The upper stripe 

 is not continued forward on the head; the other two are 

 continued onto the head and the basal portion of the tail. 

 The upper surface of the head is dark brown or olive. The
