[72713. "Ngu nok yung "= peacock snake. Back light brown, 

 with 2 median and 1 lateral dark brown stripes, the median stripes 

 cross-hatched with fine hnes of golden-yellow; belly with black spots, 

 the ground color pink anteriorly, becoming bright red posteriorly,

In the 15 Siamese snakes which I have called by this name there is 

 considerable variation from the distinctive characters given by 

 Boulenger and Smith ^ in their notes on this species compared with 

 S. mouhoti. There are constantly 19 scale rows around the body in 

 our specimens of taeniatus, and in this point our series agrees with 

 Doctor Smith's counts. But the tip of the tongue is black and the 

 remainder grayish instead of the whole organ being red (or bleached 

 white in alcohol) as Doctor Smith had observed. The headmark is 

 approximately arrow shaped, and there are no tail bars, but in every 

 case there is an incomplete collar reaching to well below the corner of 

 the mouth. A subocular is present on both sides of the head in No. 

 70340 from Nong Mong, and on one side of the head in the other 

 Nong Mong specimen. No. 70341. In all my specimens with two 

 exceptions there is one very small anterior temporal followed by one
