FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 169 



outside of forearm; a pronounced dermal appendage on heel; body 

 elongate but rather heavily built, in postaxillary region only slightly 

 less than greatest width of head; when hind leg is adpressed, heel 

 reaches to just beyond anterior corner of eye; when limbs are laid along 

 the body, knee and elbow fail to meet by a considerable interval; when 

 hind legs are bent at right angles to body, heels considerably overlap. 

 Skin of upper parts very minutely glandular, but without pustules 

 anywhere except in the anal region, where there is a row of about eight 

 pustules more or less confluent below the anus followed by two or 

 three additional rows of pustules extending onto the lower proximal 

 surface of femur; a very pronounced glandular ridge above anus; a 

 very faint, low glandular ridge encircling upper part of tympanum and 

 fading out before the shoulder is reached ; skin of tliroat and chest very 

 minutely shagreened, that of belly and lower and posterior parts of 

 femur minutely granular; no apparent skinfold across the chest, A 

 median external vocal sac. 



Dimensions. — Head and body 45 mm.; head length 15 mm., width 

 15 mm.; femur 20 mm.; tibia 23 mm.; foot 19 mm.; hand 13 mm. 



Color in alcohol. — Above pale cream buff, immaculate except for a 

 powdering of very minute dark dots on snout and anterior half of back, 

 with a slight concentration of these dots on the dermal appendage and 

 outside of foot, as well as on the ridge above the anus; ventral surface 

 also pale cream buff, immaculate. 



Color in life. — From color sketch by Sandig. Parrot green on the 

 back, fading into citron yellow on the extremities, the latter tint 

 particularly apparent on hands and feet. Ventral surface bottle green 

 to grass green. Above the anus a v/hite or yellomsh transverse line. 

 Below the anus a very characteristic group of small yellowish glandular 

 points, 30 to 40 in number and resembling pimples, called milia (little 

 seeds) ; these are grouped in transverse rows which diminish in breadth 

 towards the anus. Tjrmpanum apparently of the same color as the 

 surrounding skin. The most prominent character, by itself sufficient 

 to identify the species, is the color of the iris — cadmium orange in the 

 peripheral half, fading to light gray in the middle. Transverse pupil 

 appears as a black slit in the sleeping state and as a narrow black 

 ellipse when the animal is awake. 



Variations. — Another adult from Alto da Serra, USNM 96782, is 

 practically identical in color and structural characters with the 

 described specimen. A young frog from Bonito, just metamorphosed, 

 has small black dots Avidely scattered over its dorsal surface. A 

 third adult, MP 248, has, in addition to the minute dark dots on the 

 dorsal surface which appear to characterize this species, larger irregular 

 white «pots (presumably guanine) scattered over the back. These
