One of the commonest and most widely distributed of Malayan frogs. 

 Its coloration is very variable, and six or seven different colour- 

 varieties have been described by Captain Flower. It is known to the 

 Malays as " Katak Pisang " (plantain frog), the broad glossy leaves and 

 stems of the plantain affording it a favourite refuge. In almost any 

 verandah where plants are kept these frogs are sure to be found and 

 may be noticed towards sundown crawling about among the pots or 

 trellis work in search of insects. As is the case among many Malayan 

 frogs, the tadpoles are developed and released from the ova very rapid- 

 ly. The spawn is usually deposited in a frothy mass on leaves, twigs 

 or planks just touching, or just above, the surface of water. About 

 houses, tubs of rain water are commonly used as breeding places. I 

 remember a case in which all the tadpoles hatched from one batch of 

 eggs laid under my observation had a most curious kink in the tail ; I 

 never saw this peculiarity in others and am puzzled to account-for it. 



I have found this species common on the hills up to 5,000 feet, as 

 well as throughout the low country. 



Distribution. — Sikhim, Assam, Burma, Southern China, Hongkong, 

 Formosa, Cambodia, Cochin China, Siam, Malay Peninsula, Java, 

 Samba, Borneo, Celebes, Philippines (Flower.)
