region concave; nostril much nearer to the end of the snout 
than to the eye; interorbital space as broad as the upper 
eyelid ; tympanum very distinct, nearly as large as the eye. 
Fingers and toes rather slender, merely swollen at the ends ; 
first finger extending distinctly beyond second ; foot half as 
long as head and body; toes entirely webbed; subarticular 
tubercles rather feeble; inner metatarsal tubercle feebly 
prominent, oval, about one third the length of the inner toe ; 
no outer tubercle. The tibio-tarsal articulation reaches half- 
way between the eye and the end of the snout. Skin finely 
granulate above ; a prominent glandular lateral fold, about 
half as broad as the upper eyelid; another fold from the eye 
to the shoulder, followed by a prominent gland. Black 
above, uniform or marbled with pale brown, and with five 
whitish stripes, the middle extending from between the nostrils 
to above the vent, the upper pairrunning along the glandular 
lateral fold, the lower pair from the end of the snout along 
the upper lip, which is edged with brown, to the groin; sides 
of upper surface of snout and upper eyelids pale brown; limbs 
pale bronzy brown, with small black spots or marblings, 
which are confluent into longitudinal streaks on the sides of 
the tibiz ; hinder side of thighs black, spotted or marbled 
with white; lower parts white, uniform or spotted with 
brown. Male with a large, blackish, external vocal sac on 
each side below the mandible, extending from below the 
centre of the eye to the fore limb; a humeral gland. 
From snout to vent, g 80, ? 75 millim. 
Several specimens were obtained near Toungoo by Mr. 
Kk. W. Oates. 
This very handsome frog is most nearly allied to R. hume- 
ralis, Blgr., from which it differs in the longer head and the 
still more feebly developed digital expansions. The shorter 
hind limbs, the longer web between the toes, and the longer 
inner finger are characters which differentiate it at once 
from £. macrodaciyla, Gthr., which has a somewhat similar 
coloration.
