series of glands; arms and legs heavily crossbarred, the posterior 

 surface of the femur with several scattered round white spots; a 

 white line beginning on the heel, extending along the outside of the 

 tarsus and along the fifth toe; a similar one from elbow to outer finger; 

 a wide brown streak originating at the tip of the snout, covering the 

 whole of the loreal region, extending across and behind the ear and 

 fading out behind the shoulder; upper and lower lips with a narrow 

 sharply outlined white border; chin below this white border sepia, 

 fading out to wood brown on throat and chest, the remainder of the 

 body and lower limb surfaces being slightly paler and immaculate. 

 Color in life. — From a sketch without data b}'- Sandig. Light 

 phase: Dorsal ground color ochi'e yellow with irregular, very faint, 

 wide, drab-gray crossbars, 3 or 4 across the head, 7 or 8 across the 

 body and sometimes breaking up or anastomosing; similar but more 

 regular pale gray crossbars on upper surfaces of arms and legs; 

 posterior surface of femur campanula blue, with about 10 round black- 

 edged chrome-yellow spots arranged diagonally in pairs, the blue 

 fading out into the pale gray crossbars on upper surface of femur; 

 groin pale dull blue; a narrow seal-brown line beginning at the nostrils, 

 running below the canthus rostralis, continuing over the ear and 

 fading out on the sides; a narrow chrome-yellow line above this dark 

 line; a transverse chrome-yellow line above anus followed by a dark 

 anal patch; outer surface of forearm and tibia suffused with brown, 

 heel also brown; a narrow yellow line along outside of tarsus. Sides 

 of body spotted with yellow. Ventral surface pinkish buff on chin 

 to maize yellow on belly, with suffusions of raw sienna on lower femur 

 and tibia; hands and feet olive-buff, below irmnaculate. A double 

 row of median postanal white spots marking the postanal series of 

 glands. Iris cinnamon to russet, finely dotted with yellow towards 

 the iris, which is black and transversely elliptic. 



Dark phase: Dorsal ground color viuaceous-cionamon, with faint, 

 irregular, transverse darker markings; posterior lateral region, groiu, 

 and anterior and posterior femoral surfaces dark sepia, with round 

 black-edged yellow spots as in the light phase. A wide clove-brown 

 stripe from nostrils along loreal region and continuing part way down 

 the sides of the body. 



Variations. — In the series of 26 examples of this beautiful species, 

 certain features show considerable variation. The adpressed heel, 

 for instance, reaches in two or three instances only midway between 

 eye and nostril, in a majority of cases a little beyond the end of the 

 snout, but in some cases far beyond it. The tibiae of two specimens 

 of equal size may vary in length, and when limbs are laid along the 

 sides, laiee and elbow may or may not meet. The snout is very
