CHELONIA. 



serrated fringe on the outer edge of the leg. Adult blackish olive 

 above ; young pale olive, dotted and spotted with black. 



Grows to a length of 15 feet, or more. 



India, Ceylon, Burma, Malay Peninsula and Archipelago. 



The Marsh-Crocodile or Mugger appears to be rare in the 

 Malay Peninsula. It is recorded by Cantor, and a specimen 

 stated to be from Singapore is preserved in the Bi'itish Museum. 



It is, however, rather doubtful if Cantor's remarks really refer 

 to this species, and not to C. iwrosus. No one of the local 

 Museums possesses specimens. 



Older CHELONIA. 



Quadrate bone immovably united to cranial arches. Dorsal 

 ribs single-headed, the anterior attached between two vertebrae. 

 Body encased in a bony shell. A plastron formed of a small 

 number of elements in addition to the clavicles. jN'o sterjium.
