supraoculars and frontoparietal and parietal. Two trans- 

 verse series of small occipitals behind parietals and inter- 

 parietal. Five or six superior and six or seven inferior 

 labials to a point below pupil. Sublabials large and, except 

 anteriorly, usually separated from infralabials by small 

 granules and plates. Anterior gulars little 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, sur- 

 rounded by smaller plates and granules, in front of anus. 

 Posterior surface of forearm covered with small, nearly 

 equal-sized granules, a few rows sometimes more or less 

 enlarged. Tail long, provided with rings of large, obliquely 

 keeled scales. Femoral pores varying from 15 to 1 8 j aver- 

 age of 24 thighs, 1 7. 



The color above is yellowish or grayish brown, paler on 

 the head and tail, with the granular surfaces of the limbs, 

 body and neck, except the nuchal region, finely but obsoletely 

 reticulated with darker brown, and with very numerous 

 small, discrete, yellowish white spots two to five granules 

 in diameter. There are no longitudinal markings. The 

 head and tail are unicolor above and on the sides. The upper 

 surfaces of the hind limbs are more or less obsoletely reticu- 

 lated. The sublabials and the gular region are yellowish 

 gray, more or less suffused with black, as are also the feet 

 and tail. The lower surfaces of the legs, and the chest and 

 belly are more or less intensely black, sometimes sprinkled 

 with yellowish white dots or spots.
