FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 165 



greatly outwards. Eye large, prominent, its diameter equal to two- 

 thirds its distance from end of snout; interorbital diameter about 1}^ 

 times that of upper eyelid which is moderately narrow, almost twice 

 as great as distance between nostrils. Tympanum moderate in size 

 but very distinct, equal to one-half the eye diameter, separated from 

 eye by an interval equal to one-half its own diameter. Fingers one- 

 half webbed, fourth considerably longer than second, reaching half- 

 way onto disk of third, which nearly covers the tympanic area; a pro- 

 nounced dermal ridge along outside of forearm, extending along outer 

 finger; a rudiment of a poUex showing as a blunt knob on inside of 

 first finger; toes three-fourths webbed, fifth slightly longer than 

 third, disks of toes much smaller than those of fingers, that of fourth 

 toe covering only about one-half the tympanic area; a blunt inner 

 but no outer metatarsal tubercle; a blunt, low ridge along inside of 

 tarsus, and another slightly more apparent along outside of foot and 

 tarsus, ending on the heel in a dermal tubercle, which suggests a 

 distinct conical dermal appendage; body elongate but rather heavily 

 built, width in postaxillary region somewhat less than greatest width 

 of head; when hitid leg is adpressed, heel reaches to end of snout; 

 when limbs are laid along the body, knee and elbow considerably 

 overlap; when hind legs are bent at right angles to body, heels con- 

 siderably overlap. Skin of upper parts fairly smooth, except for 

 some scattered round spots supposed to be guanine which are slightly 

 raised; a narrow but sharp glandular ridge begmning behind eye, ex- 

 tending over tympanum and straight back along the sides lialfway 

 to groin; a pronounced glandular ridge above anus; skin of throat and 

 chest smooth, of belly and lower part of thighs heavily granular; a 

 skinfold across the chest and another across the throat. (A large 

 internal vocal sac in the male.) 



Dimensions. — Head and body 56 mm.; head length 19 mm., width 

 21 mm.; femur 28 mm.; tibia 30 mm.; foot 22 mm.; hand 16 mm. 



Color in alcohol. — Above, yevj pnle olive-buff; an irregular, wide, 

 drab-gray crossband between the eyes, extending to outer edge of e3'e- 

 lids; a heavy dotting of very fine drab spots over posterior head and 

 back, shghtly less concentrated on upper surfaces of limbs and on 

 snout and upper lip; ventral surfaces very pale olive-buff, immaculate. 



Color in life. — The following color notes were made from a typical 

 example from a series of living frogs from Manguinhos collected on 

 January 23, 1935: Upper surface brilliant yello^vish apple green, with 

 guanine spots appearing lemon-yellow. (According to A. Lutz, the 

 guanine spots are white, being composed of white crystals, but the 

 yellow appearance may be due to the overlying skin.) A narrow 

 dorsolateral stripe of citron yellow. A postfemoral patch of orpiment 

 orange, and a suffusion of this color somewhat faded out on lower
