 Rio de Janeiro. Tongue elongate, spatulate, over one-third the width 

 of mouth-opening, free behind; snout short, truncate at the tip when 

 viewed from above and in profile, the upper jaw^ extending consider- 

 ably beyond lower; nostrils projecting, about one-third as far from tip 

 of snout as from eye, horizontal, superolateral, separated from each 

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

 rostralis distinct and very concave, giving the end of the snout a 

 curiously pinched appearance; loreal region vertical, nearly flat to 

 upper lip border; a thin, sharp supraocular crest ending in a heavy, 

 raised, jutting bony ridge above tympanum and practically obscuring 

 the small, triangular parotoid; a distinct parietal crest from center of 

 supraocular crest, converging, ending behind the eye on the occiput; 

 eye large and prominent, its diameter equal to its distance from end 

 of snout; interorbital region flat, with the supraocular crests rising 

 above it, twice the width of the upper eyelid at its narrowest (anterior) 

 part. Tympanum moderately large, its greatest diameter equal to two- 

 thirds that of eye, separated from eje onlj'^ by a slight postocular ridge ; a 

 bony triangular projection on corner of upper jaw directly below 

 tympanum. Parotoids merging with the immensely developed supra- 

 tympanic crest, small, diverging posteriorly above the shoulders ; a single 

 row of pronounced conical tubercles beginning on the parotoid and con- 

 tinuing along a heavy lateral skin fold to the groin. Fingers slightly 

 webbed, with lateral ridges, their tips not dilated, fourth longer than 

 second, reaching halfway on antepenultimate phalanx of third; no 

 pollex; an oval tubercle on base of fii'st finger, and a flat round palmar 

 tubercle; subarticular tubercles well developed, single, except below 

 base of penultimate phalanx of third finger, where they are double; 

 toes one-third webbed, fringed, their tips not dilated, third a trifle 

 longer than fifth, reaching to base of antepenifltimate phalanx of 

 fourth; a small oval metatarsal tubercle and a smaller round outer 

 one; subarticular tubercles of toes well developed, all single; a fanly 

 regular row of tubercles marking the outer tarsal border. Body 

 stout, in postaxiUary region slightly greater than width of head 

 measured between tympani; when hind leg is adpressed, heel reaches 

 to center of tympanum; when limbs are laid along the body, knee 

 and elbow touch; when hind legs are bent at right angles to body, 

 heels are separated slightly. Dorsal skin minutely granular, with a
