JAYAN VIRALVE. 17-5 



being dusky for half the length of the feathers : the 

 legs are rufous-black. 



This species is found on the British coasts, and 

 on those of Kent and Sussex only ; in the vicinity 

 of Sandwich and Rye : it also frequents Hungary 

 and the confines of Turkey, and if it be the Marsh 

 Tern of Wilson (which is highly probable) it also 

 inhabits the United States of America and Brazil. 

 It affects those marshes that are well clothed with 

 rushes, and are in the vicinity of great lakes, rarely 

 appearing on the sea or its coasts : it feeds on large 

 insects, such as dragon-flies and moths, which it seizes 

 while flying. According to Wilson it lays three or 

 four olive-green eggs, spotted with brown. As before 

 mentioned, it resembles Sterna Cantiaca, but may be 

 readily distinguished from that bird by its beak, wings, 

 and tail.
