usually first supraocular plates. Four supraoculars, fourth

 oculars and frontoparietal and parietal. Two or three trans- 

 verse series of small occipitals behind parietals and inter- 

 parietal. About five superior and six inferior labials to a 

 point below pupil. Sublabials large and, except anteriorly, 

 separated from infralabials by small granules and plates. 

 Anterior gulars largest centrally, becoming gradually smaller 

 laterally and anteriorly, 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

 upper surfaces of the limbs are orange-brown or grayish 

 olive, coarsely reticulated with black. The sides of the 

 head and neck are marked with numerous large, well defined 

 black blotches. The gular region is grayish or yellow, 

 sometimes more or less suffused, dotted or spotted with 

 brick red and usually with large, well defined black mark- 

 ings, which sometimes form cross-bars. The lower surface 

 of the body is bluish, greenish or yellowish, with some 

 irregular black spots or blotches about the edges of the 

 plates. The tail is yellowish, greenish, olive, or orange-
