Description. — Adult male, USNM 96932 (cotype), Campo Bello, 

 Itatiaia, Rio de Janeiro. Vomerine teeth in two short, heavy, 

 narrowly separated transverse groups between the choanae; tongue 

 about two-thirds as wide as mouth-opening, cordiform and elongate, 

 deeply notched and free behind; snout long and pointed when viewed 

 from above, truncate at the tip and then strongly declivous in profile, 

 the upper jaw projecting greatly beyond the lower; nostrils supero- 

 lateral, projecting, their distance from end of snout one-half that from 

 the eye. Canthus rostralis relatively prominent, its outline convex 

 in front of the eye, concave behind the nostril; loreal region corre- 

 spondingly more convex than concave. Eye large and prominent, its 

 diameter two-thirds its distance from end of snout; interorbital diam- 

 eter relatively broad, slightly greater than width of the narrow upper 

 eyelid, IY2 times the distance between nostrils. Tympanum
