^0 Laceiiidie. 



31 to 36 * gular scales in a straight line bet^veen the symphysis of 

 the chin-shields and the median collar-plate, juxtaposed in front, 

 larsfer and imbricate near the collar ; no gular fold. Collar free, 

 curved or, more frequently, angular, composed of 7 to 11 plates. 



Scales granular and smooth on the nape, larger, flat, rhombic, 

 obtusely or rather strongly keeled on the body, subimbricate towards 

 the tail, a little smaller on the sides ; 45 to 59 scales across the middle 

 of the body, 2ii to 26 in a transverse series between the hind limbs. 



Ventral plates in regular longitudinal and transverse series, all 

 except the outermost broader than long, but never twice as broad 

 as long, in 10 longitudinal and 30 to 33 transverse series. 3 or 4 

 preanal plates on the median line, usually very feebly enlarged in 

 females, the last 2 to 3 times as broad as long in males. 



23 to 29 femoral pores on each si'.le,-^ the two series meeting in the 

 middle. Digits with 3 series of scales ; toes with moderately strong 

 lateral denticulation, the denticles stronger on the outer side of the 

 fourth toe but shorter than the diameter of the toe ; 21 to 23 strontcly 

 uniearinate lamellae under the fourth toe. 



Upper caudal scales much larger than posterior dorsals, oblique, 

 truncate, and strongly and diagonally keeled, basals as long as broad 

 or a little broader than long, lower smooth or very obtusely keeled 

 in the basal part ; 22 to 28 scales in the fourth or fifth whorl. 



Young streaked with black and white, the black streaks the 

 broader and spotted with white ; -5 or 6 white streaks on the nape, 

 4 or o on the body, 3 on the base of the tail; another white streak 

 on each side, from the tympanum to the groin ; limbs vrith la,rge 

 round white spots. The striation disappears or is reduced to traces 

 in the adult, which are grey above, spotted, speckled or reticulate with 

 blackish, the blackish spots often forming 2 or 4 longitudinal series. 

 A female is remarkable for a black, light-edged vertebral stripe on the 

 body, the sides being spotted with blackish, and a light, black-edyed 

 vertebral streak on the nape. Lcwer parts white.
