This Rana is unlike any other in form, suggesting Lepto- 

 hrachium hasseltii. It might as well be placed in the subgenus 

 Rana, with which some specimens agree entirely in the shape of the 

 toes, whilst others show a groove on the terminal discs, thus con- 

 stituting a connecting link between the subgenera Rana and Hylo- 

 rana. The presence of a parotoid gland in the larva and young is 

 peculiar to some of the species included in the latter subgenus, e.g. 

 R. alticola, and this consideration has determined its allocation. The 

 coloration is also unique in the genus Rana in the upper parts being 

 lighter than the lower, and in the temporal region being some- 

 times lighter than the sides, thus standing in comparison to R. 

 temporalis like positive and negative in photography. 



[The young frog of this species frequently attains a relatively 

 large size before losing the vestiges of its tail. N. A.'\
