This slender and elegant species was discovered on the Cumbraes 
in the Firth of Clyde by Dr. MacDougall of Glasgow, who sent a

it has seldom been observed in any of those localities. On the 
other hand, it is known to have nested recently in Wales, and a few 
pairs have been seen in Norfolk and Suffolk ; while Mr. Oswin Lee 
appears to have identified breeding birds on the Moray Firth, Its 
temporary disappearance may have been due in some measure to 
the increase of the larger and stronger Common Tern, before which, 
as Dr. Bureau informed me of his own knowledge, three colonies 
of the Roseate Tern had successively given way on. the coast 
of Brittany within a few years. Indiscriminate egging on the
