webs, and more than half of the inner near the shafts from the points, 

 but gradually becoming- less towards the base ; the shafts and interior 

 margin quite white to the tip. In winter the black on the head either 

 disappears or becomes mottled with white ; the tail considerably forked; 

 the outer feathers dashed with cinereous on the exterior webs ; legs 

 dusky, with a tinge of red. 



Young birds, not maturely feathered, are more or less clouded with 

 brown on the upper parts of the body and wings, and the head spotted 

 with white. * " In the month of August," says Temminck, " the young- 

 begin to moult ; then the feathers of a bluish ash-colour, without any 

 spot, begin to be speckled and bordered with brown ; the feathers of 

 the tail become whitish grey with the first spring- moult, and perfectly 

 white with the second autumnal moulting ; the bill becomes of a deep 

 black, the point being yellowish."* 



This bird was first noticed by Mr. Boys, of Sandwich, where it is 

 not uncommon, and communicated to Dr. Latham, who first gave it to 

 the world. It does not appear to be so plentiful as either of the other 

 species ; for in a whole summer's residence on the coast of Sussex and 

 Kent, where the others are in plenty, we were not able to procure 

 more than two specimens ; nor could we ever find where it bred. It 

 comes to us and retires about the same time as the others, and has no 

 doubt been confounded for the common tern, to which it bears very 

 great resemblance, except in size and in the colour of the bill and legs ; 

 the bill of this is also much stronger, the legs much longer, and the 

 tail not so much forked. It has, however, all the manners and habits 

 of the common species, as far as we have been able to collect. We are 

 informed that it breeds on the Sandwich coast, but have never, with cer- 

 tainty, heard of its eggs being found. We were favoured with an egg, 

 said to belong to this bird, from Mr. Lewin, and have seen another 

 from the same gentleman, in the cabinet of Dr. Latham ; both of which 

 appear in size and colour to be that of the common tern.
