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.
