Vomerine teeth in two slightly oblique series commencing close 
to the inner front edge of the choane. Head moderate, rather de- 
pressed ; snout long, pointed ; interorbital space as broad as, or 
broader than, the upper eyelid; tympanum very distinct, nearly as 
large as the eye. Fingers rather long, first extending beyond 
second; toes moderate, nearly entirely webbed; fingers and toes 
with slightly swollen tips and strong subarticular tubercles ; inner 
metatarsal tubercle small, oval; a small rounded tubercle at the 
base of the fourth toe. The hind limb being carried forwards along - 
the body, the tibio-tarsal articulation reaches nearly the tip of the 
snout. A prominent, rather broad, glandular lateral fold ; another 
from beneath the eye to beyond the shoulder. Reddish brown 
above, sides of head and body darker ; a light line on the upper lip, 
sometimes missing ; flanks and hinder side of thighs marbled with 
dark brown; beneath immaculate, or brown-spotted on the throat
