continuing above the tympanum, encountering the bony knob, and 

 continuing straight back above the shoulder for a short distance, 

 fading out as a loose fold of skin; a slight glandular line above anus; 

 skin of throat and chest very faintly tubercular, that of belly, postanal 

 region, and lower femur coarsely granular, with a pair of more or less 

 regular lines of postanal enlarged glands ending in a large wartlike 

 gland at the ventral surface ; a few enlarged granules on back of lower 

 femur; a heavy skinfold across the chest. (Vocal pouches probably 

 lateral and external in the male.) 



Dimensions. — Head and body 70 mm.; head length 23 mm., width 

 26 mm.; femur 36 mm.; tibia 39 mm.; hind limb 120 mm.; fore limb 

 44 mm. 



Color in alcohol. — Dorsal ground color russet to walnut brown, with 

 a few indistinct dark dots near the base of the tubercles and between 

 the eyes; a narrow black line along can thus rostralis, below this a sepia 

 area cut in two by an irregular wide white stripe; dark dots on upper 

 lip below eye and on side of head; lateral ground color pearl gray, with 

 small scattered dots and numerous, irregular, more or less quadrangu- 

 lar black spots, their upper borders fading out into the ground color 

 of the back, their centers lighter or with small pale dots; a similar dark 

 marking on the front of each shoulder; a slate-gray postanal patch 

 bordered above by a narrow black line and a wider light area; upper 

 surfaces of limbs with wide, chocolate, dark-edged crossbars, some 

 having a border of small dark dots instead of a line; heel ridge bor- 

 dered with slate color, the tubercles light buff; throat and chest drab, 

 suffused with indistinct seal brown reticulations and dots; belly and 

 lower limbs drab gray, indistinctly mottled with darker drab. 



Remarks. — This species superficially resembles Hyla venulosa because 

 of the diagonal dark and light blotches on the sides, the heavy cross- 

 bars on the legs, and the light patch under the eye. The feet are dif- 

 ferent, however, as the fourth toe is relatively longer and the web 

 shorter in G. microdisca.

1939. Gastrotheca viridis Lxttz and Lutz, 1939a, pp. 81-83, 89, pi. 2, figs. 4, 4b, 

 (type locality, Bonito, Serra da Bocaina, Rio de Janeiro). 



Description. — Since no example of this species has been examined by 

 me, the original description is reproduced as follows: 



Gastrotheca viridis is characterized by the partly pitted, but loose, skin over 

 the head, light colour (apple-green) allied to striking markings, very short leg, 

 smooth skin, subcircular, hardly emarginate tongue, and oblique groups of well- 

 separated vomerine teeth, a combination of characters not found in any of the 

 species described.
