FROGS OF SOUTHEASTERN BRAZIL COCHRAN 3 



carpal tubercle ; no pronounced rudiment of a poUex or ridge on fore- 

 arm ; toes webbed at the base and distinctly fringed laterally, the tips 

 not dilated, third and fifth subequal and reaching to base of penulti- 

 mate phalanx of third ; subarticular tubercles on toes small and numer- 

 ous; outer and inner metatarsal tubercles weak and undifferentiated; 

 apparently no tarsal ridge. Body rather stout and toadlike, in post- 

 axillary region equal to greatest width of head; when hind leg is ad- 

 pressed, heel reaches to axilla ; when limbs are laid along the sides, knee 

 and elbow are slightly separated; when hind legs are bent at right 

 angles to body, heels barely touch. Skin above set with flat, coarse, 

 tubercular swellings extending onto the upper surfaces of the limbs and 

 forming apparently a double row on the snout, becoming more evident 

 on sides of head behind corner of mouth and along sides of body; 

 ventral siu-faces minutely shagreened anteriorly, with coarse granules 

 on throat and a few on chest and anterior belly; posterior belly nearly 

 smooth; a few indistinct tubercles on posterior femur, and a few 

 smaller, sharper ones around the anus; no supratympanic or dorso- 

 lateral glandular ridges; no skinfold across the chest. (No external 

 vocal sac apparent in the male.) 



Dimensions. — Head and body length 22 mm.; head length 7 mm., 

 width 7.5 mm.; femur 8 mm.; tibia 8 mm.; foot 8.5 mm.; hand 5 mm. 



Mathematical analysis (in percentage of the total length): 



Color in alcohol. — Dorsum vandyke brown to clove brown, with a 

 pale drab line along posterior part of upper arm ending on the elbow; 

 a pale buff spot below eye extending on the edge of lip to corner of 

 mouth; ventral region pale buff, with a median seal brown spot on 

 center of chin, a paler brown marking across the throat extending 

 behind on the middle of the chest, the adjoining lower surfaces of 

 arm and palm of hand being pale buff except for a brown extension of 

 the dorsal color around the wrists; posterior part of beUy and lower 

 surface of femur pale buff, the lower tibia and tarsus colored like the 

 back, the sole of the foot pale buff. The line of demarcation between 

 the dark dorsal and light ventral color is strong on the posterior femur, 

 but less distinct on the sides, owing to the light pigment on the 

 tubercles there.
