This water snake is very common in Bangkok according to Dr. 

 M. A. Smith's account of The Snakes of Bangkok. In Dr. Hugh M. 

 Smith's collection, all but one of the specimens were caught at that 

 city. It is called "ngu pla," meaning "fish snake." 



In all cases the scales around the body are in 19 rows, the two 

 outer being smooth. The only noteworthy feature of the head 

 scalation is that No. 70320 has but one anterior temporal; this is 

 rarely the case, two being the rule.
