Zweifel A few minutes collecting at this spot Turned up only one frog, though conditions seemed ideal. This frog has little trace of distinct mark- ing on the dorsal surface of the body, al- though dark bars are evident on the upper surfaces of the tibia and femur. The surface of the back between the dorsolateral lines is bright reddish brown, as are the upper surface of the hind legs. Red marks are present even out on the hind toes. The toe tips are not dark. Throat markings as of the dark, vermiform type.
