2. The snout is less pointed and the convexity of the outhnes of the sides of 
the head as seen from above more marked and more regular. The length 
of the head is usuall}^ less than the breadth. The upper jaw projects very 
little beyond the lower. 
3. The hind hmb is shorter, the length of the tibia being in adult frogs con- 
siderably less than half that of the head and body. The fourth toe is also 
much shorter. 
4. The dark and pale longitudinal stripes and bars conspicuous on the sides of 
the head and fore quarters of the young R. tigrina are totally absent. 
The pale mid-dorsal line, however, is sometimes present. There appears 
to be in the young a pale straight stripe extending from the upper posterior 
border of the tympanum to the lower anterior border of the orbit. The 
upper lip is marked with comparatively long vertical dark bars, while 
the lower lip is white, sometimes with irregular dark bars and bordered 
below with a dark line or row of spots. The throat is spotted with black ' 
and the spots as a rule extend all over the ventral surface ; they are 
always small and frequently tend to be connected together in such a way 
as to form a more or less complete reticulation. 
Larva. From notes that Dr. Boulenger has been kind enough to send me it is 
clear that the tadpole from Bangkok described by Flower as that of R. tigrina was 
really that of R. rugulosa. It differs from the larva of the true R. tigrina in its much 
less flattened body (the abdomen being highly convex), in its strictly terminal mouth 
and lateral eyes. The armature of the mouth is identical. Dr. Boulenger has kindly 
sent me a specimen. 
Distribution. R. rugulosa occurs all over Burma (except perhaps in Arrakan) in 
continental and northern Peninsular Siam, southern China, Formosa and perhaps the 
Philippines. The species was described from south-east China.

In addition to these specimens I have examined an adult from Fokien in the 
Shanghai Museum and one from" Koh Samuie, an island off the north-east coast of 
the Malay Peninsula, which Mr. Boden Kloss has kindly lent me. The latter is 
figured on plate v. Dr. Boulenger has sent me notes on specimens in the British 
Museum. 
1 In one specimen sent me for examination by Dr. Smith, the pigmentation of the throat is rather of the nature 
of a suffusion.
