Description. — Adult male, USNM 96765, Bonito, Serra da Bocaina, 

 Rio de Janeiro. Vomerine teeth in two short, heavy, transverse, well- 

 separated patches behind the posterior borders of the choanae; tongue 

 a little more than half as wide as mouth-opening, oval, slightly in- 

 dented on its free posterior border; snout obtusely angular when 

 viewed from above, slanting backwards towards the lip border in 

 profile, the upper jaw consequently extending far beyond the lower; 

 nostrils lateral, not projecting, their distance from end of snout about 

 four-fifths that to eye, separated from each other by an interval about 

 twice as great as their distance from eye. Canthus rostralis sharp and

well defined, forming a right angle with the vertical loreal region, 

 which appears slightly concave because of the curving upper lip 

 beneath it. Eye large and prominent, its diameter very slightly less 

 than its distance from end of snout; interorbital diameter equal to 

 width of the broad upper eyelid, about two-thirds that of distance 

 between nostrils. Tympanum large and very distinct, about one-half 

 the diameter of the eye, separated from eye by an interval equal to 

 one-half its own diameter. Fingers free, their tips dilated with disks 

 only slightly wider than the terminal phalanx, which is equipped (in 

 this specimen) with wide dermal fringes; a pair of distinct pads sepa- 

 rated by a median longitudinal furrow on top of each disk, even the 

 first; fourth finger much longer than second, which reaches only to 

 base of penultimate phalanx of thu'd; first finger very slightly shorter
