NINETEENTH GENUS—H YDROPHID.”. 
Aquatic snakes, found in the China seas and in the Persian 
Gulf and coast of Madagascar. All have flat, two-edged, eel- 
shaped tails, and are exceedingly poisonous. Some varieties 
attain a length of 12 feet or more. Giinther says they most 
abound in the seas between Southern China and Australia. 
They have generally small jaws, and smaller fangs than the 
land snakes. Cases of their bites have produced death in 
from 1 hour 15 minutes to 72 hours. The last was an unusual 
case, and the bitten person was administered alcohol freely 
during the time he remained alive, which undoubtedly pro- 
longed greatly the action of the poison; at the same time, 
other causes (suggested on another page), may have com- 
bined to deprive it of its greatest activity at the time it was 
introduced into the blood.
