THE SNAKES OF BANGKOK. 101 
Length. Upto1120 mm. The tail is short, measuring about 
one-seventh of the total length. 
Color (in life). Above, very dark olive-green, sometimes almost 
black, with regular cross-bars formed by chains of yellow or brown 
spots, and less well-defined longitudinal lines produced by a median 
spot in each scale. The dark ground-color tapers on the sides into a 
series of transverse bars, which are prolonged to the mid-line on the 
belly, but are continuous beneath the tail. The notches thus formed 
are deep yellow in color, the ventrals, pale yellowish or whitish, 
"Head brown, labials and chin-shields yellow, the scales edged with 
black. 
This description applies to the young and young adults, but as 
age advances the dorsal bars and lines tend to increase in size and 
obscure the ground color, so that in old specimens the pattern is 
seldom apparent. 
The drawing of the head is by Mr. C. L. Groundwater, to whom 
I am also indebted for all the other drawings in connection with this
