NOTE 



ON THE 



FOSSIL CROCODILE, 



OF THE 



SIVALIK HILLS.

Superintendent, Doab Canal. 



Of the skulls of the existing Crocodile from which the measurements 

 accompanying this note have been taken, one belongs to an animal 7 feet 

 long of which we have the perfect skeleton ; and the other was stated by 

 the person from whom it was procured, to have belonged to an animal of 

 12 feet : we have a correction however in the smaller specimen, which 

 was carefully measured ; and taking this as a type, the animals being of the 

 same species ( C. Biporcatus, Cuvier), a mean of four measurements gives 

 us a length of 132.09 inches, or 11 feet .09 inches, for the latter. In fixing 

 this specimen as belonging to an animal of 1 1 feet, we shall not therefore 

 be far from the truth. 



There is so much difference in the few comparative measurements that 

 we have been able to obtain of the fossil, with these two skulls, that it is 

 hardly possible to take any proportion of the existing animal as a guide to 

 that of the fossil : the measurements taken separately would in some cases 

 reduce our fossil to that of an animal of 1 1 feet, with distinct ocular proof 

 to the contrary ; in others the fossil animal would be 17 feet long, which
