 are dentated and palmated, like those of African Crocodiles. The 

 Gravials are chiefly remarkable for their long head, its type being 

 the Gavial of the Ganges, or Gavial longirostre. It is of a deep 

 watery green colour, having on the upper part numerous irregidar 

 brown spots ; in the young, the back and limbs are transversely 

 banded with black ; the lower part is of a pale whitish yellow ; 

 the jaws are . marked with brown, the claws are of a clear horn 

 colour. This species is not so carnivorous as the others, and is con- 

 sequently less dreaded. 



The Gavial of the Ganges, G. Gangeticus, is supposed to be the 

 largest of the existing Saurians ; its length, as given by Dumeril, 

 is seventeen feet four inches. .
