 dorsal than lateral, projecting slightly, their distance from end of 

 snout two-thirds their distance from eye. Canthus rostralis not

 snout; interorbital diameter a little greater than that of upper eyelid, 

 equal to inteval between nostrils. Tympanum distinct, its greatest 

 diameter five-sixths that of eye, separated from eye by an inteval equal 

 to one-third its own diameter. Fingers moderate, with faint lateral 

 ridges, slightly webbed at base, first finger a little longer than second 

 and fourth, reaching to base of ultimate phalanx of third; a pair of 

 heavy black-tipped thumb spurs in the male; a small palmar callus; 

 metacarpal tubercles well developed. Toes long, fringed, webbed at

 and an outer one nearly the same in size; a heavy tarsal ridge, ending
