Description. — Adult male, USNM 97048, Camuiho da Macahyba, 

 Natal, Rio Grande do Norte. Vomerine teeth in two heavy A- 

 shaped, nearly contiguous long patches between and behind the 

 choanae; tongue half as wide as mouth-opening, widely notched on 

 its free posterior border; snout blunt and truncate at the tip when 

 seen from above, bluntly rounded in profile, the upper jaw extending 

 only slightly beyond lower; nostrils superolateral, scarcely projecting, 

 their distance from end of snout less than one-third that from eye, 

 separated from each other by an interval equal to their distance from 

 eye. Canthus rostralis rounded and indistinct; loreal region slightly 

 concave and slanting outwards to the widely flaring upper lip. Eye 

 large and prominent, its diameter equal to its distance from nostril; 

 interorbital diameter equal to width of upper eyelid, slightly less than 

 interval between nostrils. Tympanum very large and distinct, almost 

 as great as eye diameter. Fingers free, not fringed, their tips pointed 

 and without grooves, first much longer than second, which equals 

 fourth; no pronounced poUex, but palmar and subarticular tubercles 

 well developed; toes without webs or fringes, their tips similar to 

 those of fingers, third longer than fifth and reaching beyond base of 

 antepenultimate phalanx of fourth; a small prominent oval inner 

 and a round outer metatarsal tubercle; a blunt, low tarsal ridge from 

 inner tubercle to heel; body fairly stout, in postaxillary region equal 

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

 posterior corner of eye ; when limbs are laid along the sides, knee and 

 elbow are well separated; when hind legs are bent at right angles to 

 body, heels slightly overlap. Skin of upper parts entirely smooth 

 except for a few faint granules on top of snout; a weak supratympanic 

 ridge; ventral surface smooth except for some gi^anules on posterior 

 thighs and below arms. Apparently no discoidal abdominal fold or 

 skinfold across the chest. Male probably with internal vocal sac 

 and without spurs on the hand. 



Dimensions. — Head and body 51 mm.; head length 18 mm., width 

 18 mm.; femur 20 mm.; tibia 21 mm.; foot 18.5 mm.; hand 11 mm. 



Color in alcohol. — Dorsum cinnamon, lightening to fawn on sides 

 and limbs; traces of four or five large irregular squarish spots down 

 middle of back and a few similar dorsolateral spots; dark crossbars 

 on tibia and femur; venter pale drab, immaculate.
