choane. Habit stout. Head short, snout rounded ; canthus ros- 
tralis indistinct ; interorbital space two thirds the width of the 
upper eyelid; tympanum nearly as large as the eye. Fingers 
pointed, first not extending beyond second ; toes broadly webbed ; 
subarticular tubercles of fingers and toes small; a small, blunt, 
inner metatarsal tubercle. ‘The hind limb being carried forwards 
along the body, the tibio-tarsal articulation reaches hardly the 
tympanum. A narrow glandular lateral fold, sometimes quite 
indistinct, especially on the hinder half of the back ; sides of body 
with small, pearl-like tubercles. Brown above, more or less 
distinctly speckled with grey ; small, rounded, dark-brown spots on 
the back, transverse ones on the limbs; beneath yellowish or light
