Description. — Adult male, BM 1928-l*12-30, Urucum, near Co- 

 rumbd, Mato Grosso. Vomerine teeth in two short, heavy, /~\-shaped, 

 well-separated series between and behind the posterior borders of the 

 choanae; a row of well-developed maxillary teeth; tongue about 

 three-fifths the width of mouth-opening, an elongate oval in shape, 

 with a slight indentation on its posterior border which is moderately 

 free; snout rather elongate, pointed when viewed from above, rounded 

 in profile, the upper jaw projecting considerably beyond the lower; 

 nostrils lateral, scarcely projecting, their distance from end of snout 

 about two-thirds that to eye, separated from each other by an interval 

 equal to their distance from eye. Canthus rostralis rounded but well 

 defined, loreal region slightly concave, nearly vertical, the upper lip 

 scarcely projecting below it. Eye moderately large, its diameter 

 equal to its distance from the nostril; interorbital diameter equal to 

 that of the very wide upper eyelid, very slightly greater than distance 

 between nostrils. Tympanum large, distinct, about three-fourths 

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

 about one-third its own diameter. Fingers webbed only at the base, 

 fourth much longer than second, reaching to base of disk of third, 

 which covers nearly one-half the tympanic area; a pronounced rudi- 

 ment of a pollex on first finger; a faint low glandular ridge along outer
