FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 267 



other by an interval a little less than their distance from eye. Canthus 

 rostralis curved and evident, due to the very concave, nearly hori- 

 zontal region below it. Eye large, prominent, its diameter 1% its 

 distance from nostril, a little less than its distance from end of snout; 

 interorbital diameter 1% times the vndth of upper eyelid, a little 

 greater than interval between nostrils. Tympanum not visible. 

 Fingers moderate in length, free at the base but with dermal ridges on 

 the sides, their tips ending in ball-like disks which are very slightly 

 wider than the adjoining phalanx; second finger longer than first, 

 shorter than fourth, reaching to base of penultimate phalanx of third; 

 no pronounced pollex, but both palmar tubercles well developed; 

 subarticular tubercles moderate; toes three-fourths webbed, their tips 

 enlarged into small disks, third longer than fifth, reaching to base of 

 penultimate phalanx of fourth, which is fairly long; subarticular 

 tubercles rather prominent; a large blunt oval inner and a triangular 

 outer metatarsal tubercle; a distinct glandular tarsal ridge; body 

 broadly elliptical in shape, in postaxiUary region equal to greatest 

 width of head; when hind leg is adpressed, heel reaches to anterior 

 border of eye; when limbs are laid along the sides, knee and elbow 

 touch; when hind legs are bent at right angles to body, heels fail to 

 meet. Skin of upper part of head and back roughened with fine gran- 

 ules; some irregular larger granules along the dorsolateral region from 

 eye almost to gi-oin; a curving dermal ridge from posterior corner of 

 eye to front of shoulder; a large, flat, semicircular inguinal gland; 

 throat, chest, and lower surface of arms coarsely granidar, belly and 

 postanal region minutely granular; lower surface of legs quite smooth. 

 Traces of a slight skinfold across the chest. No external vocal sac. 



Dimensions. — Head and body 51 mm.; head length 19 mm., width 

 22 mm.; femur 23 mm.; tibia 23 mm.; foot 22 mm.; hand 13 mm. 



Color in alcohol. — Dorsum burnt umber, lightening to cinnamon 

 posteriorly, a wide transverse lighter band between the eyes; traces 

 of darker crossbands on upper sm'face of forearm and tibia, and of 

 small light dots on posterior femur; venter cinnamon, darker on the 

 throat and chest, where many small light spots occur; tips of toes 

 apparently light, with a central dark spot on the upper side of the 

 terminal phalanx. 



Color in life. — Based on my color notes of two adults from Tijuca. 

 The larger, USNAl 97417: Dorsum very dull clove brown mixed with 

 russet and sepia on the limbs; a wood-brown crossband between the 

 eyes; venter close to chocolate brown, spotted with white; inguinal 

 glands the same color; iris mostly Indian purple with very small 

 coppery flecks and dark Ihies. The smaller, USNM 97418: Similar 

 but less russet on back and more russet between crossbars on hind 

 legs; chin clove brown, throat seal brown lightening to olive gray on
