FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 193 



Color in alcohol. — Dorsum pinkish buff, becoming lighter in a chev- 

 ron-shaped patch between eyes and on top of snout; in front of this 

 patch a wavy slate-gray line from nostril to eye along canthus ros- 

 tralis, and below it another slate-gray line from tip of snout to lower 

 eyelid, slightly less regular in outline; back with numerous olive spots 

 and reticulations which are heavier on the postaxillary region, lighter 

 between the insertion of the arms, and heavier again between the eyes 

 just posterior to the light chevron-shaped interocular patch; femur 

 without crossbars, immaculate posteriorly, with a few light olive spots 

 anteriorly; tibia, foot, and forearm also with pale light olive spots; 

 disks of toes and fingers olive above, paler below; ventral surface 

 immaculate pinkish buff. 



Color in life.- — From a color sketch by Pugas of a female with eggs, 

 USNM 96674, from Bonito. Dorsum pale pinkish buff, deepening to 

 buff on eyelids and top of head; canthus rostralis and loreal region seal 

 brown; a heavy Y-shaped seal-brown marking extending from behind 

 the eyes, its posterior part lightening to olive, bordered by a white 

 stripe, then by a sepia stripe seeming to conform with the glandular 

 supratympanic ridge, then by another pale stripe below this. Many 

 Gne sepia dots all over back and sides, especially concentrating to form 

 pale crossbands on tibia and forearm and darkening the toe and finger 

 disks. Iris apparently yeUow ochre. 



Variations.- — Some newly metamorphosed young from the same 

 series measure 10 mm. in total length. The dark reticulation on the 

 back of adults is often rather prominent, as is also the characteristic 

 pale interocular bar, often with a contrasting dark horseshoe-shaped 

 figure following it. The dark canthal stripe is distinct in some and 

 nearly absent in others. Vomerine teeth may be between the posterior 

 borders of the choanae, or actually behind this level. A number of 

 adult females without eggs show the skin of the dorsolateral region 

 very loose and apparently stretched, so that it can be inflated almost 

 Uke one of the vocal vesicles. 



Remarks. — The female carries on the sides under a fine but distinctly 

 pigmented membrane about nine large eggs which become dark when 

 the tadpoles begin to develop. The latter are born with the posterior 

 extremities already free and develop generally in the water of bro- 

 meliads, where the frog was found in Tijuca. 



The eyes, directed forward, may be very prominent; the pupil is 

 oval, the iris bronzy with black vermiculations. A glandular fold runs 

 back from the small tympanum, covering its upper border. 



Young individuals are recognized by the light frontal and super- 

 orbital spot, which may disappear temporarily at any time.
