superior and five or 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 later- 

 ally 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, con- 

 vex 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 7 to 2 1 on each thigh. 



The color above is dark brownish olive, without any 

 indications of longitudinal lines at any age, but with small, 

 discrete, bluish or yellowish white spots or ocelli on the 

 sides and back of body, thighs and base of tail. These spots 

 cover from one to eight granules, are sometimes edged with 

 black, are more or less equidistant, and sometimes form 

 transverse rows on the sides. The limbs are brownish or 

 grayish olive above, black below; the forelimbs are unicolor, 

 while the hind, both above and below, are spotted in the 

 same manner as the body. The top and sides of the head and 

 neck are olive, unmarked. All the lower surfaces are jet black 

 from the gular region to the tip of the tail, unmarked ex- 

 cept on the hind limbs and base of tail and occasionally the 

 posterior part of the belly, where whitish spots similar to 

 those of the upper surfaces may be seen.
