as long as broad or slightly longer; canthus rostralis distinct, 
slightly angular; loreal region sloping obliquely, some^vhat con- 
cave behind nostril; diameter of eye slightly less than length of 
snout, reaching slightly beyond nostril ; nostril one and one-third 
times farther from eye than tip of snout; tympanum small, cir- 
cular, distinct, two-fifths to one-half diameter of eye, separated 
from eye by a distance equal to three-fourths its diameter ; inter- 
orbital region less than the width of a single eyelid; eyelids 
bounded above by slight grooves; a slight, shallow, longitudinal 
groove on snout, continued to between nostrils; skin of back 
smooth; sides somewhat granular, or with short longitudinal

and disk of second finger ; second finger very slightly shorter than 
fourth, neither reaching base of disk of third ; diameter of largest 
finger disks greater than tympanum ; subarticular tubercles large, 
rather flattened; toes slightly webbed at base, the membranes 
not reaching first subarticular tubercles; toes with small disks,
