 ture; three parietals; four supraoculars ; seven supercil- 

 iaries; two frontoparietal^; scales on middle of eyelid 

 enlarged; nasal in contact with second upper labial, the 

 postnasal and first upper labial being separated; posterior 

 gular scales small, abruptly smaller than the anterior, the 

 line of demarkation between them being emphasized by 

 the two rows nearest the latter being slightly smaller 

 than the rest of the posterior ones; plates of collar rather 

 large, in several rows, the marginal largest; dorsal gran- 

 ules smooth, rather large; ventral plates in eight longitu- 

 dinal and thirty -one transverse rows; three large pre- 

 anals, the posterior two widest; four rows of brachials, 

 the posterior much the smallest; antebrachials continuous 

 with brachials, in two rows, the outer a little the larger; 

 granules along posterior edge of lower surface of forearm 

 very slightly enlarged; lateral caudal scales oblique, rather 

 strongly keeled, pointed posteriorly. 



The color above is pale brown with three longitudinal 

 bluish white lines on each side, and one equally distinct, 

 narrow and well-defined line along the middle of the 

 back. The limbs are a little paler than the ground-color

 faint light line along the back of the thigh. Under parts 

 whitish, tinged with blue. Tail unicolor, grayish.
