FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 339 



anus. A transverse fold of skin across the throat probably denotes 

 the presence of an internal vocal sac. 



Dimensions. — Head and body length 57 mm.; head length 20 mm., 

 width 26 mm.; femur 21 mm.; tibia 20.5 mm.; foot 24 mm.; hand 

 16.5 mm. 



Mathematical analysis (in percentage of total length) : 



Color in alcohol. — Dorsum seal brown, with a short middorsal white 

 line on the sacrum, an irregular white stripe on the sides from behind 

 the tympanic area nearly to groin, and a white bar from eye to pos- 

 terior angle of mouth; a tawny interocular bar, and two indistinct, 

 light, wide blotches on the upper lip, one below and the other in front 

 of the eye; legs and arms with irregular light and dark crossbars, 

 becoming less distinct pro.ximally; venter olive-buff, the throat of the 

 male black; palms of hands and feet sepia, with the tips of the toes 

 and fingers as well as their tubercles pale. The female has practically 

 the same coloration except that the throat is ohve-buff like the rest 

 of the lower surface. 



Remarks. — The voice of the male is a musical, high-pitched, metallic 

 coo-coo twice repeated. Two adults were taken during copulation 

 after dark on March 13, 1935, in wet, marshy ground below a reservoir 

 at the Country Club, near Bello Horizonte, in the vicinity of the type 

 locality. The female deposited a gelatinous mass of eggs the next 

 day, each egg yolk measuring about 2 mm. in diameter. A meta- 

 morphosing froglet with well-developed legs and a 5-mm. tail was 

 taken the same night. 



The adults live in holes in the ground, and can disappear in a moment 

 in soft son by the powerful action of the hind feet in burrowing.
