 the scutes usually in 4, rarely in 6, longitudinal series, those of

Hub. India, Ceylon, Burma, Malay Peninsula and Archipelago. 

 This is the common Crocodile of India, found in rivers, marshes, 

 and ponds, and extending west to Sind and Baluchistan. 



This species is easily distinguished from G. porosus by its 

 shorter snout and by the presence of five teeth in each prae- 

 inaxillary bone, whilst the adult of the latter has but four.
