Capt. Flower says it is a true water-frog and appears to occtir 

 only at low elevations. It is most active both on laud and in the 

 water ; it can hop over the surface of a pond, much as R. cyano- 

 plihjctis does in India, and also jump right out of the water. 

 Owing to the vivid green colour of its back exactly matching the 

 colour of the weeds in a pond, it is often difficult to see but for 

 its bright golden eyes.
