502 8. TEIID& 



limbs are brown marked with darker, and with longitudinal 

 stripe along the posterior surface of the thigh. The lower 

 surfaces are yellowish or bluish white. 



The young are similarly colored but show no light spots 

 between the lines. The upper line on each side usually is 

 slightly narrower and less distinct than the other two. A 

 few young individuals show, in addition, a distinct, light, 

 median dorsal line. In somewhat larger specimens, the 

 brown ground color becomes a little lighter in places, and 

 presents a faintly mottled appearance. In still larger in- 

 dividuals small whitish spots appear between the light lines, 

 first on the posterior part of the back, and the adult color- 

 ation is assumed. In larger adults these light spots become 

 more numerous and sometimes join the longitudinal light 

 lines. These light lines, however, retain their distinct- 

 ness, although they may become broader with age. Differ- 

 ent individuals of the same size show much variation in the 

 extent to which these markings have been developed, but 

 they are, nevertheless, clearly due to increased age. The very 

 largest specimens (formerly regarded as a distinct species, C. 

 scalaris) show a further change of color pattern. The dark 

 ground is completely broken up by transverse enlargements 

 of the light spots and stripes, the darker brown or blackish 

 areas forming more or less irregular transverse bars or 

 stripes.
