external metatarsal tubercle (the digging ‘spade’) on inner (ventral) 
border of foot just distal to tarsus ; free cutting edge of spade directed 
lateroventrally ; toes in order of decreasing length, 4, 3, 5, 2, 1 ; web 
but slightly scalloped; one phalanx free on all toes but fourth, on 
which two phalanges extend beyond web. 
Tongue broad, width more than half that of mouth at angles of 
jaws, attached to floor of mouth by slightly more than half its length ; 
internal nares large, close to anterior border of upper jaw ; vomerine 
teeth in two oval transverse groups between internal nares. 
Back relatively smooth; dorsal surface with many small, low, 
rounded tubercles, more numerous, larger and higher on sides of body ; 
ventral surface of body smooth or with but few low rounded areolae ; 
buttocks slightly rugose. 
Color (in life) above dark green, with scattered spots of dusky; 
four (or two) incomplete longitudinal stripes of dull white, inner pair 
in line with inner margins of orbits, the outer in line with tops of 
tympanic membranes ; tubercles on back and sides tipped with red or 
orange in young individuals; ventral surface plain white; throat 
region (vocal sac) blackish in males, dusky in females. Females lack 
the conspicuous longitudinal dorsal streaking of white, this being 
broken and much less extensive.
