THE SNAKES OF BANGNOK. 185 
this part of the treatment was not sufficiently 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 usually 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, 
yellowish 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. 
Distribution. From India to China and the Malay Archipelago. 
This concludes the Snakes of Bangkok. Three other species 
will probably have to be recorded, namely, Dryophis prasinus, Hyp- 
sirhina plumbea, and T'yphlops 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 years 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- 
ately the War broke out before he was able to do so.
