Description. — Adult female, USNM 96440, Estrella, Rio de Janeiro. 

 Vomerine teeth in two short, heavy, posteriorly converging, widely 

 separated series between the choanae; tongue oval, slightly more 

 than one-third as wide as mouth-opening, with a small but distinct 

 indentation in its very free posterior border; snout moderate in 

 length and bluntly pointed when viewed from above, flat and sloping 

 forwards and do\ATiwards in profile, the upper jaw not projecting 

 beyond the lower; nostrils lateral, scarcely projecting, located almost 

 at the tip of the snout, separated from each other by an interval equal 

 to their distance from eye. Canthus rostralis prominent though 

 rounded; loreal region concave and nearly vertical. Eye moderate in 

 size, not very prominently projecting; its diameter about three-fourths 

 its distance from end of snout; interorbital diameter about 1% times 

 the width of upper eyelid, much greater than distance between nostrils. 

 Tympanum distinct though covered by skin, its greatest (vertical) 

 diameter equal to three-fifths the eye diameter, separated from the 

 eye by an interval equal to one-half its diameter. A very heavy, low 

 parotoid gland extending back from posterior corner of eyelid to a 

 point about a head length from its origin where it merges abruptly 

 with the rather glandular dorsolateral skin. Fingers long and slender, 

 unwebbed, first shorter than second and apparently easily opposable; 

 fourth shorter than third, disk of third covering about one-half the 

 t5anpanic area; a distinct semicircular thin projection at base of 

 first finger; a glandular ridge from base of fourth finger to elbow; 

 toes webbed only at the base, first longer than second and opposable 

 to it; disk of third covering about one-half the tympanic area; no 

 inner or outer metatarsal tubercles; no tarsal ridge on inside, but a 

 rather indistinct one beginning on outside of fifth toe, extending along 

 tarsus and becoming much more apparent across the heel; no dermal 

 appendage on heel; a distinct transverse glandular ridge in front of 

 the anus. Body quite elongate, the width of head contained 3 times 

 in distance from tip of snout to coccyx well anterior to anus; when 

 hind leg is adpressed, heel reaches to center of tympanum; when limbs 

 are laid along the sides, knee and elbow are separated by a considerable 

 interval; when hind legs are bent at right angles to the body, heels 

 slightly overlap. Skin of upper parts thick and glandular or somewhat 

 pustular, depending on the preservation. Skin of throat and chest 

 smooth; of belly, lower surface of thighs, forearm, tarsus, and region
