Description. — Adult, Lutz coll., Serra das Orgaos, Rio de Janeiro. 

 Vomerine teeth in two small, round, well-separated groups far behind 

 and well within the inner borders of the choanae. Maxillary teeth 

 well developed; apparently no transverse row of odontoids on the 

 palatine bone; tongue covered with very small glandules, medium 

 sized, its width equaling about one-half the mouth-opening, notched 

 and free posteriorly; a small toothlike process in front of lower jaw; 

 snout obtusely pointed when seen from above, rounding in profile, 

 the upper jaw projecting beyond the lower; nostrils lateral, nearer to 

 tip of snout than to eye, separated from each other by a distance 

 slightly less than their distance from eye. Canthus rostralis promi- 

 nent, the loreal region concave, and the upper lip flaring out below it. 

 Eye large, its diameter nearly equal to its distance from end of snout; 

 mterorbital diameter equal to width of upper eyelid. Pupil trans- 

 versely elliptical. Tympanum distinct, small, the encircling rim not 

 very apparent posteriorly, its diameter equal to one-half that of eye, 

 separated from eye by an interval equal to two-thirds its own diameter. 

 Fingers free, without lateral ridges, the tips of the third and fourth 

 dilated into moderately large disks which are heart-shaped (notched 

 on top), that of the third finger covering slightly more than one-half 

 the tympanic area; tips of first and second fingers only a little en- 

 larged, ball-like; fourth finger longer than second, reaching to base of 

 disk of third; no rudiment of a pollex; subarticular tubercles single, 

 strongly developed, but carpal callosities scarcely evident; toes free, 

 with distinct lateral ridges, all their disks somewhat enlarged and 

 notched, the disk of the fourth toe about equal to that of third finger; 

 fifth toe considerably longer than third; a small, oval, prominent inner 

 metatarsal tubercle and a smaller round outer one; subarticular tu- 

 bercles of toes well developed ; no plantar tubercles ; a prominent trans- 

 verse tubercle on the heel; no tarsal ridge. Body slender, in post-
