largest of which, at its edge, are somewhat larger than the 

 scales on the chest. Back and sides covered with small smooth 

 round granules, much larger medially than laterally. Tail 

 conical except where depressed at base, covered with whorls 

 of weakly keeled scales, a little smaller than those of belly. 

 Scales of chest and belly smooth, those on limbs with dis- 

 tinct keels. Femoral pores 15 to 21. 



Most of the large specimens have lost their original 

 tails, and are now provided with regrowths. 



There is considerable variation in the intensity, and some 

 in the distribution, of color in the large series at hand, but 

 the general pattern is the same in all the specimens. Very 

 young individuals are fully as brightly colored as older 

 ones, and females as brightly as males. The largest speci- 

 mens, however, appear somewhat duller than others, espe- 

 cially on the posterior part of the back. One of the brightest 

 individuals, which has been in alcohol little more than a 

 month, may be described thus: On the anterior half of the 

 back are three transverse bands of intense black, bordered 

 posteriorly by others of olivaceous yellow (orange in life). 

 The first of these bars connects the shoulders. The second 

 is the shortest and narrowest j near its anterior edge are two 

 round yellow spots, about half the size of the tympanum. 

 The third is the largest and best defined. It is bordered in 

 front by a narrow band of plumbeous, which separates it 

 from another of olivaceous yellow. The remaining space 

 between these black bands is finely dotted and reticulated 

 with black, sepia, and azure. The posterior half of the back 

 is similarly banded, but the colors are here so dull as to 

 appear as if viewed through a thick and discolored epidermis. 

 In front of each shoulder is an azure spot about the size 

 of the tympanum. Half-way between the upper edges of 

 these spots and the tympana are smaller spots of the same 

 color, and others may be seen on the dorsal median line of
