Siamese name: ngu khio (applied to all green snakes). 



Seems to be fairly common in the southern parts of the country. In the 

 North, however, it is rather rare and I only remember having seen a single specimen 

 from Koon Tan. Its place is here taken by the preceding species. It is entirely 

 aboreal, though it of ten keeps to low bushes.
