FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 187 



fifth subequal, disk of fourth as large as that of third finger and also 

 nearly covering the tympanum; a distinct projecting tubercle at base 

 of first toe, but no apparent outer metatarsal tubercle; no dermal 

 appendage on heel; no inner tarsal ridge; a distinct glandular outer 

 tarsal ridge which extends over the heel almost as an appendage and 

 ends on the femur; body rather elongate, in the postaxillary region 

 about equal to the greatest width of head; when hind leg is adpressed, 

 heel reaches anterior comer of eye; when limbs are laid along the 

 sides, knee and elbow greatly overlap; when hind legs are bent at 

 right angles to body, heels considerably overlap. Skin of upper parts 

 very finely glandular, the flesh beneath it almost waxlike in con- 

 sistency; no glandular ridges above the tympanum; skin of throat 

 and chest very finely glandular with minute pustules scattered over 

 it; skin of beUy and lower surface of femur finely granular; a skinfold 

 across the chest. (An external vocal sac in the male.) 



Dimensions. — Head and body 24 mm.; head length 7 mm., width 

 7 mm.; femur 11 mm.; tibia 12 mm.; foot 10.5 mm.; hand 7 mm. 



Mathematical analysis (in percentage of the total length): 



Color in alcohol. — A few days after preservation, this and the other 

 specimens faded to an immaculate pearly olive-buff above and below, 

 with a suffusion of buff on the belly and lower femur. A very close 

 inspection of the dorsal skin under the microscope reveals some scat- 

 tered groups of very minute vinaceous dots which give the slightest sug- 

 gestion of pale pinkish spots when observed closely by the unaided eye. 



Color in life. — A few days after capture, the following color notes 

 were taken on the living specimens: Color of back between emerald 

 and apple green, very intense. Legs and arms above much paler, 

 waxlike, pea green to pale paris green, this green reduced on the thighs 

 to a narrow, median, punctulated line. Ventral surface pale malachite 

 green, the peritoneum opaque white, the rest of the skin translucent. 

 Finger tips olive-yeUow. Bones perfectly visible through the flesh. 

 Iris orange-rufous in center, mixed with gray and oil green at pe- 

 riphera, sometimes brassy. Pupil very narrow, edged with white, 

 notched above and below. Tympanum not at all visible in life, 

 covered by skin of the same color and texture as that on the rest of 

 the head. Its waxy appearance is very striking.
