26 SNAKES FROiM DEHl.I. 



36. Bungarus annularis Schl, 



One specimen of this very dangerous snake was found 

 in Mr. Prakke's collection. According to Dr. Hagen this 

 snake is very common in Dehli , often reaches a length of 

 six feet and is generally seen in swampy countries some 

 time before sunrise or after sunset. 



37. OpJiiophagus elaps Schl. 



One very young specimen from Langkat. Dr. Hagen 

 captured specimens of ten and eleven feet and maintains 

 that this most dangerous of all Dehli snakes is very swift 

 in its movements and of such an angry mood that it at- 

 tacks people at the slightest disturbance and sometimes 

 even without any evident reason. 



38. Naja tripudians Merr. 



The local variety of this species in Dehli is of a dark- 

 brown or sometimes black colour, with two black oval 

 spots surrounded with white on the sides of the neck , but 

 without the curved line that unites these spots across the 

 back in the typical specimens of the continent. Dr. Ha- 

 gen maintains this snake to be an animal with nocturnal 

 habits , as it is seldom seen in the daytime. It is very 

 slow in its movements and hardly ever stirs to go out of 

 the way when met with in the dark. It can spit its saliva (?) 

 to a distance of two or three feet and aims at the eyes of 

 the intruder. 



39. Bothrops gramineus Shaw. 



One specimen in Mr. Prakke's collection. Dr. Hagen 

 considers the species of the genus Bothrops, though pro- 

 vided with large fangs, as less dangerous than Bungarus 

 annularis. 



40. Bothrops ery thrums Cantor.
