finger to elbow; toes webbed very slightly at the base, first shorter 

 than second, disk of third covering nearly the entire tympanic area; 

 a small blunt inner but no outer metatarsal tubercle; no tarsal ridge 

 on inside of foot, but a very distinct one beginning on outside of fifth 

 toe, extending along tarsus to heel; apparently no transverse gland- 

 ular ridge in front of anus. Bod}^ moderately elongate, the width 

 of head contained slightly less than 3 times in distance from tip of 

 snout to coccyx; when hind limb is adpressed, heel reaches to anterior 

 corner of e3^e; when limbs are laid along the sides, knee and elbow 

 overlap considerably; whea hind legs are bent at right angles to the 

 body, heels overlap. Skin of upper parts faintly shagreened, wdth a 

 faint glandular dorsolateral ridge beginning above the shoulders and 

 fading out at the beginning of the sacral region; sldn of throat and 

 chest very minuteh^ granular, that of belly and lower femur a little 

 more heavily granular. A circle of pustules around anal region. 

 Apparently no skinfold across the chest. No externa-l vocal sac. A 

 roughened dark excrescence on callosity at base of first finger. 



Dimensions. — Head and body 35 mm.; head length 10 mm., width 

 11 mm.; femur 16 mm.; tibia 17 mm.; foot 11 mm.; hand 9 mm. 

 The forearm is well developed, the upper arm very weak, hence it 

 becomes difficult to extend the arm properly. 



Color in alcohol. — Upper surface of head and body vinaceous, this 

 color likewise appearing on outer surfaces of forearm and hand be- 

 tween the weak glandular ridges as well as in a thin stripe, along 

 upper part of femur, which widens upon the tibia and extends upon 

 outer tarsus and foot between the faint glandular ridges. Remainder 

 of upper surface, sides, and ventral surface pale olive-buff, immaculate. 



Color in life. — From a painting of the described cotype by Sandig. 

 Upper parts of head, body, and limbs apple green to grass green, 

 with a few minute dark spots sparsely scattered over it ; lateral region 

 as well as front and back of femur cadmium orange to orange-vermilion, 

 invaded by indigo spots. Forearm cream anteriorly, cadmium yellow 

 towards elbow; fingers and toes immaculate chrome yellow. Iris white 

 to light beryl green; pupil a black vertical ellipse. 



Another color sketch by Honorio of an example from Tijuca, 

 collected November 13, 1929, shows the following colors: Upper 

 surfaces apple green, darkening slightly on the head; a number of 

 black ocellated spots scattered on the back and some more numerous 

 minute black dots on the head; sides of body and limbs ochraceous 

 rufous; upper surfaces of feet and hands immaculate ochraceous-buff; 

 nuptial pad at base of first finger black; iris pale cream-buff; pupil 

 a black vertical slit. 



Variations. — Only one partly grown frog from Serra da Bocaina, 

 USNM 96550, is at hand. This specimen shows a decided difference
