18. CNEMIDOPHORUS 507 



Anterior gulars largest centrally, becoming gradually smaller 

 laterally and anteriorly, and changing abruptly to smaller 

 posterior gulars. Scales on center of collar quite large, those 

 on its edge usually smaller but sometimes larger. Back 

 covered with small, smooth, convex granules. Eight longi- 

 tudinal and about 37 transverse rows of ventral plates. About 

 four series of large preanals. Posterior surface of forearm 

 covered with small, nearly equal-sized granules. Number 

 of plates on limbs very variable sometimes seven rows of 

 brachials, three of antebrachials, seven of femorals, and 

 four of tibials. Tail very long and provided with rings 

 of large, obliquely keeled scales. Femoral pores varying 

 from 18 to 28. 



The color above is gray or grayish sepia fading to olive 

 gray laterally, with three longitudinal dark chestnut bands 

 on each side, which (bands) are twice as wide as the intervals 

 between them, and are so invaded by spots of the ground 

 color, as to resemble series of confluent brown maculations. 

 These dark markings often are more or less obsolete, par- 

 ticularly on the anterior part of the body. The limbs are 

 reticulated with coarse chestnut lines. The upper surface 

 of the head is olive, palest on the snout. The gular region 

 and the sides of the head are blotched with walnut brown. 

 Many of the ventral plates have black basal markings. The 

 tail is tawny olive, tinged and spotted with dark chestnut. 



Young individuals have five bluish white longitudinal 

 lines on a black ground which is more or less broken by 

 spots of the same color as the lines. Their tails and hind 

 limbs are suffused with bright flesh color. In one there are 

 six instead of five pale lines.
