THE SNAKES OF BANGKOK. 185 



this part of the treatment was not sufficient!}' deep to be of any 

 value. 



Length. Up to 870 mm. 



Color (in life). Above verdant green, below pale green, yellow- 

 ish green, bluish green or light blue. There is usualh^ a well-marked 

 flank line, upon the last row of the costal scales beginning at the neck 

 and running the entire length of the body and tail. It may be white, 

 3'ellowish or pale blue in colour. Dorsum of tail and tip, reddish brown. 

 Interstitial skin blackish, the colour often extending on to the adjacent 

 scales and forming indistinct dark cross bars. Iris golden yellow with 

 vertical pupil. 



This snake is well known to the Siamese, and its local name 

 may be relied upon. 



Disfrihidion. From India to China and the Mala}'- Archipelago. 



This concludes the Snakes of Bangkok. Three other species 

 will probablv have to be recorded, namely, Dri/ophis prashias, Tlyp- 

 sirhina plumbea, and Ti/phlops siamensis. The two former are fairly com- 

 mon in the country districts outside the city, and there appears no reason 

 why they should not be found in Bangkok. Of the earth snake, 7'. 

 siamensis, only one specimen is so far known, obtained by M. Mouhot 

 many j'ears ago. Last year, however, Major Sprater was given a snake, 

 caught at Bangsue. which I considered to be this species, in spite of 

 some slight differences in lepidosis. He took it home with him to 

 compare with the type specimen in the British Museum but unfortun- 

 atelv the War broke out before he was able to do so.
