and five or six inferior labials to a point below pupil. Subla- 

 bials large and, except anteriorly, separated from infrala- 

 bials by small granules and plates. Anterior gulars largest 

 centrally, becoming gradually smaller laterally and anter- 

 riorly, 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 1 6 to 22 on each thigh. 



The color above is yellowish or grayish brown, irregu- 

 larly marbled with dark brown or black, which dark mark- 

 ings usually form from seven to nine more or less irregu- 

 larly broken black bands or longitudinal rows of spots. 

 These dark markings may take the form of reticulations on 

 the back and vertical bars on the sides. The upper sur- 

 faces of the limbs are brown or grayish olive, recticulated 

 with black or dark brown. The sides of the head and neck 

 are marked with numerous large, well-defined black 

 blotches. The tail is yellowish, greenish, or olive brown 

 above, darkest along the keels of its scales. The scales of 

 the central series on the lower surface of the tail nearly all 

 are heavily marked with black. The lower surface of the 

 body is bluish, greenish or yellowish, with numerous, irreg- 

 ular black spots or blotches. The gular region is grayish or 

 yellow, usually with large, well defined black markings, 

 which sometimes form cross-bars.
