Form of the head and body resembling that of Hylorana. Snout moderately long, 
rather pointed, flat above, with distinct canthus rostralis, and with the sides rather high 
and subvertical. Tympanum nearly the size of the eye (females). Vomerine teeth in 
two oblique series between the choane. First finger longer than the second. ‘Toes with 
the ends swollen, ends of the fingers less so. Web reaching to the proximal end of the 
penultimate phalanx, which, however, shows a narrow fringe in its whole length. A 
small inner metatarsal tubercle. Hind limb without tarsus shorter than the body, 
fourth toe (from metatarsal joint) nearly one-half the length of the body. Body 
smooth, with the exception of a rather broad and prominent glandular fold along each 
side of the back. Back greenish, with numerous or few black specks and spots. 
A black stripe runs from the end of the snout along the lower edge of the canthus 
rostralis and of the glandular fold. An oblique black stripe descends from the upper 
corner of the tympanum towards the shoulder-joint. Upper lip with a more or less 
distinct whitish stripe. Hind limbs without cross-bands and with the concealed parts 
unspotted. Lower parts whitish.
