Pinang. Individuals 15 ft. in length are not uncommon ; some 

 attaining to 20 it. and upwards are reported to occur. In rivers 

 a single one will often appropriate to himself a limited district, 

 which, if it happens to be in the vicinity of a village, will soon be 

 perceived in the loss of the grazing cattle. Instances of Malays, 

 who, to avenge the loss of a relative, have watched the crocodile, 

 and by diving from below plunged a kris into its heart, are on 

 record. The eggs are white, the shell hard, of a cylindrical form, 

 upwards of 3 in. in length, and about 1| in. in diameter."

 Burma, Malay Peninsula and Archipelago.
