 to nearly so great an extent as in the Indian Cobra. 



The Hamadryad feeds exclusively on snakes, small 

 pythons, kraits, rat-snakes, and the common cobra 

 entering into its bill of fare. 



Captain G. H. Evans, in the Journal of the Bombay 

 Natural History Society, tells the following story, told him

The bite of the Hamadryad produces death in man 

 in from one to two hours. According to Nicholson, an 

 elephant which he saw bitten by this snake died within 

 three hours. 



N. melanoleuca and iV. nigricollis, both of Tropical 

 Africa, are remarkable for their power of ejecting their 

 poison at a considerable distance, and are consequently 

 both known to the natives as " spitting snakes." 



In the RiNGHALS, Sepedon hcemachateSy of South Africa, 

 the only representative of the genus, which is separated 

 from the true cobras by its keeled dorsal scales, the " spit- 

 ting " habit is highly developed, for, when disturbed, the 

 snake invariably sits up, dilates a very large hood, and ejects
