124 TERN. 



quills, but the exterior feather on each side white on the outer web, 

 margined with ash; shape of the tail a little forked ; legs dull red; 

 claws black. — Said to inhabit various parts of Europe. 



It is most likely a Variety of the last, as we have observed more 

 or less white between the legs of some specimens. Colonel Montagu 

 supposes this to be the Black Species, in immature plumage,* and 

 that the black on the under parts does not appear till after the first 

 moult; also that both sexes are black beneath in the breeding season.
