with small keeled scales. The nostril, which is large and laterally 
placed, is surrounded by three shields and soft smooth skin. 
The species is found throughout India, from Bombay to Bengal, 
in Ceylon, Burma, and Siam. It is particularly common in Burma, 
around Rangoon. For walking in the jungle and rice-fields, the 
natives of this region encase their feet and legs in a special kind of 
jack-boots made of coarse jute-cloth, in order to protect themselves 
from the bites of this snake, which cause a large number of fatal 
accidents. 
The Daboia ascends the Himalayas to an altitude of 5,250 feet. 
It lives in thickets, under stones, and in the clefts of rocks. When 
disturbed it makes a terrible hissing, but bites only when attacked 
or irritated- 
It feeds upon small vertebrates, such as mice, rats, birds, and 
frogs, and often enters houses in pursuit of rats. 
“Schrott had the opportunity of observing a Daboia on the

reptile had its neck thrown back and its head in a horizontal 
position ; its bright eyes followed all the movements of the dog, to 
whose barks it replied by shrill hisses. It was only waiting for an 
opportunity to strike. Schrott called off the dog, and the snake 
at once disappeared among the high grass close by. Next day it 
was killed at the same spot” (Brehm). 
The venom of this viper is terribly potent. According to Russell, 
a large dog exhibited symptoms of poisoning five minutes after 
being bitten. At the end of a quarter of an hour it lay down, uttering 
heartrending cries, began to breathe with difficulty and noisily, was 
seized with spasms of the jaws and cramps, and died in frightful 
agony less than half an hour after the wound was inflicted. Fowls
