42 VENOMS 



Total length, 640 millimetres ; tail 50. 

 Habitat : Malabar. 



All the snakes belonging to the genus Callophis are remarkable 

 for their bright and varied colours, whence the generic name, which 

 signifies " beautiful snakes." 



They feed exclusively on other snakes belonging to the Family 

 Galamaridoi ; consequently they are not found in regions where 

 Calamaridfe do not occur, as, for instance, in Ceylon. 



They are essentially terrestrial, and live in old tree-trunks, or 

 clefts in rocks. They are sluggish, slow-moving, and chiefly 

 nocturnal. 



As a rule they do not seek either to defend themselves or to bite; 

 consequently fatal accidents caused by them are scarcely known in 

 the case of human beings. Their venom, however, is very toxic 

 to animals. 



(e) Doliophis. 



This genus exhibits the same characters as Callophis, except 

 that the poison-glands, instead of being confined to the temporal 

 region, extend a very long way on each side of the body, to about 

 one-third of its length, gradually growing thicker and terminating 

 at the base of the heart.

 or lighter longitudinal streaks ; tail red beneath ; belly red, crossed
