 the absence of the suboccipital scutes. 



It is typically an inhabitant of tidal waters and 

 is sometimes found swimming at sea, out of sight 

 of land ; it seldom goes inland to any great distance 

 from the sea. It is a man-eating species and many 

 human lives are said to be destroyed by it in India 

 and surrounding countries. A British "blue book" 

 states that in British India 244 deaths were caused 

 by Crocodilia in the year 1910.

This animal, which inhabits the Ganges and 

 other rivers of northern India, is, with the possible 

 exception of the preceding species, the largest of 

 the Crocodilia ; it is said to reach a length of thirty 

 feet, which is twice that of a very large Florida

It is a timid animal and, in spite of its huge size, 

 dashes quickly into the water on the approach of
