The number of ventrals is less, viz., 135 to 147 ; 



anal divided. Sub-caudals 66 — 82. Hence 



it is considered a different species (Dryophis 



perroteti).* 

 In Burma and Bengal the common Whip Snake 



is replaced by the 



BUFF WHIP SNAKE (Dryophis prasinus).f 



It is very similar to the common Whip Snake, 

 but differs as follows : — 



The snout, though very long, has no flexible 

 appendage. 



There are one or more loreal shields present. 

 The ventrals are more numerous, viz., 203 to 

 234 ; anal divided (very rarely it is entire). 

 Sub-caudals 155—207. 



The colour varies. Sometimes green with a 

 white lateral stripe. But it may be light 

 ochre with white belly and a lateral ochre 

 stripe. Or, it may be pale olive or grey- 

 brown with a yellow stripe along each side of 

 the lower parts. 



It has been known of a pure white. 



The interstitial skin of the neck is black and 

 white.
