 inland. The Cormorants are to be found in all well watered dis- 

 tricts in India and Burma, one species only P. carbo being found 

 commonly on the sea coast. 



The Darter has an inland distribution similar to that of the 

 Cormorants. 



The remaining families, the Gannets, the Tropic-birds and the 

 Frigate-birds are all entirely confined to the sea and ocean.

 fat, that may be thrown overboard. F. I. IV, 352.

 otomach, but blubber of dead animals and scraps thrown over- 

 board ire eagerly swallowed/' E. B. C. N. H., 62.
