I have never known this snake to bite when handled, or make 
any attempt to escape. It feeds, 1 believe, entirely upon fish. Its 
Siamese name, ‘“ngu krading”, is given to it on account of the stiff, 
unbending attitude which it assumes when caught. I have been in- 
formed by a high authority in the language that the word “ kradang ” 
cannot properly be used in this sense; it is, however, the explanation 
commonly given by the country people, though one would certainly 
have expected, knowing their aptitude for picking out salient features, 
that they would have chosen the “ tentacles” on this occasion. 
Length. 770 mm. 
Color (in life). Above, reddish brown, with a dark, irregu- 
lar, longitudinal stripe on either side of the vertebral line, and a 
broader lateral one commencing at the nose and passing through 
the eye. Below, pale yellowish, with very similar stripes, the two me- 
dian of which border the ventral scales. Anteriorly, some dark dorsal 
cross-bars, and a series of white, dark-edged, ventral spots. 
Distribution. Siam and Indo-China.
