to base of disk of third, which nearly covers the tympanum; a well 

 developed poUex equipped with a small but very sharp spur; toes 

 nearly three-fourths webbed, third a little shorter than fifth; toe disks 

 small, that of fourth covering the small tympanum completely; a 

 distinct inner but no outer metatarsal tubercle; a distinct iimer tarsal 

 ridge, and a similar glandular ridge crossing heel above the dark heel 

 patch. Body rather elongate, in postaxillary region much narrower 

 than greatest width of head. When hind leg is adpressed, heel reaches 

 between eye and nostrU; when limbs are laid along the body, knee 

 and elbow overlap; when hind legs are bent at right angles to body, 

 heels overlap. Skin of dorsum uniformly smooth; a glandular ridge 

 encirclmg tympanum, extending diagonally downwards and ending 

 behind arm above axilla; throat fairly smooth, chest and belly and 

 lower femur coarsely granular; no apparent skinfold across chest. 

 A very large vocal sac extending entirely across the throat and almost 

 to the ears. 



Dimensions. — Head and body 41 mm.; head length 14 mm., width 

 15 mm.; femur 16 mm. ; tibia 21 mm. ; foot 22 mm. ; hand 20 mm. 



Color in alcohol. — This specimen has faded badly. There are still 

 visible 3 narrow dark lines crossing the upper femur, whose posterior 

 surface is immaculate, and a few irregular dark patches on upper 

 tibia. 



Color in life. — From original description: Dorsum maize yellow 

 with numerous gi-ay dots. Sides of body, concealed parts of legs, 

 arms, and webs chrome yellow; venter paler; a series of irregular
