in the Sea Terns, while the tail is short and the 

 lateral feathers are slightly rounded, though more 

 pointed than in the Marsh Terns. The hill is re- 

 markably robust and the tarsus proportionately 

 longer than in any other species. Both Selby and 

 Audubon compared specimens of the Marsh Tern of 

 North America, S. arariea, Wilson, with Montagu's 

 type of S. anglica in the British Museum, and 

 agreed in considering them identical. The geo- 

 graphical range of this species, therefore, is very 

 considerable.
