Second, third, and fourth supraoculars separated from supcr- 

 ciliaries by small convex granules. Similar granules between 

 third and fourth supraoculars and frontoparietal and parietal. 

 One to three transverse series of small occipitals behind 

 parietals and interparietal. About five superior and five, 

 six, or seven inferior labials to a point below pupil. Sub- 

 labials large and, except anteriorly, separated from infra- 

 labials by small granules and plates. Anterior gulars largest 

 centrally, becoming gradually smaller laterally and anter- 

 iorly, and changing rather abruptly to smaller posterior 

 gulars. Scales on center of collar larger than those on its 

 edge. Back covered with small, smooth, convex granules. 

 Ventral plates in eight longitudinal rows. Three or four 

 large plates, surrounded by smaller plates and granules, in 

 front of anus. Posterior surface of forearm covered with 

 small, nearly equal-sized granules. Tail long, provided 

 with rings of large obliquely keeled scales. Femoral pores 

 varying from 17 to 23 on each thigh. 



The color above is yellowish or grayish brown, darker 

 on the neck and anterior half of the body. Along the mid- 

 dorsal region are more or less definite longitudinal mark- 

 ings formed by the ground color and dark brown or black 

 lines, spots or reticulations. On the sides, these black mark- 

 ings tend to form vertical bars more or less separated by 

 narrower bars or series of spots of the ground color, which 

 in some specimens is here pale brownish gray or bluish white. 

 The upper surfaces of the limbs are brown or grayish olive, 

 without markings. The sides of the head and neck are 

 sometimes marbled indefinitely with black. The gular 

 region is grayish or blackish, sometimes nearly unicolor but 

 usually more or less definitely reticulated or marbled with 

 black. The lower surface of the body is bluish or greenish 

 gray, with numerous, irregular black spots on the anterior 

 portions of the plates. These black markings vary much
