E.\cei)t for some difTerences in colouration, examples from Bang- 

 kok agree entirely with A'an Ivam|)eu's description of thosefrom Batavia. 



My specimens were greenish brown or brown above, speckled 

 with darker, and with a dark mark running through tiio eye and along 

 the flank to the base of the tail. Sides below marbled with olive, 

 muscular portion of tail light brown, crests colourless except for a dap- 

 pling of reddish. Belly yellowish white, speckled with red, throat 

 brown. A light vertebral lino and another along the lateral fold on 

 either side may be present in the fully grown tadpole. The vivid 

 green of the back of adult is not seen until the frog is at least one- 

 third grown.
