Indian Museum. 
Mr. I. H. Burkill has recently called my attention to certain 
frogs eaten in Burma and represented by specimens in the collec- 
tion of the Reporter on Economic Products to the Government of 
India. Among these specimens are several that appear to represent 
a species hitherto confused with Rana tigrina and here described 
aS a 
Rana burkilli, sp. nov. 
Closely allied to Rana tigrina, Boie, from which it may be dis- 
tinguished by the following characters :— 
(1) The snout is much less strongly pointed and does not 
project so far beyond the mouth, so that the upper 
jaw when viewed from below appears to be of nearly 
the same width throughout instead of being distinctly 
broader in front than at the sides. 
(2) The tibio-tarsal joint falls short of the ear, as a rule by 
a considerable distance. 
(3) The internal metatarsal tubercle is somewhat feebly 
developed. 
(4) The skin of the back and the dorsal surface of the thighs 
is more warty than is usually the case in R. tigrina. 
(5) The dorsal surface is of a dull brownish or greyish colour 
spotted with black, the surface of the longitudinal 
ridges and the tips of the smaller warts being whitish. 
The ventral surface is marked with black, the mark- 
ings sometimes taking on a reticulate character all 
over the belly. There is no pale dorsal stripe. 
Localtttes—Mandalay, Upper Burma (J. Anderson, Indian 
Museum); Tavoy (types) ; Bassein, Pegu. 
Length of type specimen (No. 16569, Indian Museum) gt mm. 
without legs. 
None of the specimens have vocal sacs, but as most of Piet 
have been eviscerated their sex cannot be ascertained. 
Mr. Burkill tells me, on the authority of the Burmese, that 
the new species buries itself in the embankments of rice-fields dur- 
ing the dry weather, while R. tigyina remains active throughout the 
year. The two species occur in the same localities.
