rostralis from nostril to eye, and from posterior edge of upper 

 eyelid backward above tj^mpanum, and then obliquely down- 

 ward to middle of side; this stripe seems to be upper margin 

 of broad dark band that extends obliquely downward behind 



tympanum; head-and-body length, 38.7 mm plicata (p. 173)

5. A tarsal fold present in adults, indistinct in young or immature 



individuals 6

 adhesive disks nearly as large as tympanum; toes two-thirds

 on penultimate phalanx of third and fifth toes; the hind limb 

 being carried forward along the body, the tibio-tarsal joint 

 reaches to center or at most to anterior margin of eye; tym- 

 panum less than or slightly more than one-half the diameter 

 of the eye and overhung by an indistinct dermal fold; dis- 

 tance from ej'e to nostril somewhat greater than transverse 

 diameter of eye; vomerine teeth in two elongate clusters, 

 presenting an obtuse angle posteriorly, each group consisting 

 of about four teeth, and situated between the choanae; tongue 

 circular, scarcely notched behind; canthus rostralis indis- 

 tinct; loreal region fiat, oblique; snout prominent, rounded; 

 skin of upperparts fairly smooth; sides rugulose; abdomen 

 and under surface of thighs granulated; a dermal fold across 

 chest; upperparts dark olive (in alcohol), with a short longi-

 tympanum distinct, generally one-half to three-fourths, 

 rarely one-third, diameter of eye; adhesive disks of fingers a 

 little larger than those of toes and often nearly as large as 

 tympanum; the hind limb being carried forward along the 

 body, the tibio-tarsal joint usually reaches to anterior margin 

 of eye, occasionally between eye and tip of snout, and rarely 

 beyond tip of snout; toes one-half webbed (fig. 20, e), with 

 narrow dermal fringe on terminal phalanges; a tarsal fold; 

 tongue broad, notched behind; canthus rostralis indistinct;
