Mr. "Wray sent me the following- note about this specimen, 

 which has been identified by Mr. Bouleuger. 



"Flying Frog collected in Piah A' alley. Upper Perak : above, it 

 is a lovely bright green, with hands and feet tinted yellow and a 

 white patch on each thigh. Below, it is pink dotted over with 

 yellow. The sides of the body are chrome-yellow, and its webbed 

 hands and feet are yellow and black." 



In answer to further enquiries Mr. Wray tells me he did not 

 see it fly, but caught it sitting on a tree. The name " Flying 

 Frog" seems to be taken from A. E. Wallace ('The Malay Archi- 

 pelago,' edition 1S94, fig. on p. 30).
