142 U. S. NATIONAL MUSEUM BULLETIN 2 06 



The pattern is as variable as the bodily proportions. In some 

 there is no dorsal pattern at all, the back being a uniform pale gray 

 (greenish in life) or darker brown. There is often a dark interorbital 

 bar, which in many cases is enlarged to a distinct triangle. Behind 

 this above the shoulders there is usually a dark W, a A, or a )(, 

 sometimes followed by other smaller spots, with quite often a dark 

 transverse A or V at the sacrum, or any combination of these mark- 

 ings may occur. There are not, however, the long, relatively straight 

 dark and light dorsolateral stripes which evidently characterize 

 specimens of the typical H. rubra from the Guianas. 



The tibia, when patterned at all, usually has three fairly wide, 

 dark crossbands, although sometimes these are more numerous and 

 narrower. The femur is nearly always crossbanded on top, while 

 on its posterior surface it possesses heavy, dark reticulations on a 

 light ground, with these light areas often formed into fairly regular 

 circular spots, or sometimes an irregular ellipse extending halfway 

 down the femur. Its anterior surface is a little less heavily reticulated 

 with dark, while the groin and the posterior lateral region often have 

 a large hght spot with more or less irregular dark borders, or this 

 whole area may be reticulated with dark over the light ground. 



Remarks. — The voice is a raucous kraw, kraw, kraw like that of H. 

 rubra. Eggs were laid in the laboratory by captive specimens, but 

 were not allowed to develop. No tadpoles are definitely Imown up to 

 the present time. The adults live in holes high in bamboos and trees, 

 and frequently in bromeliads.
