Characters of Callophis, except that the poison-glands, instead of 
being confined to the temporal region, extend along each side of the 
body for about one third of its length, gradually thickening and 
terminating in front of the heart with club-shaped ends. The 
presence of these glands may be detected without dissection by feeling 
the thickening and rigidity of the cardiac region in the second third 
of the body, the heart being shifted further back than in other 
snakes owing to the extension of the glands.
