with grey; the edges of the feathers being yellowish- 
white. Wing-coverts, rump, and tail, deep grey. Base 
of the bill reddish-brown. Feet and toes bluish-grey, 
tinged with flesh-red. In this state the present species 
appears to be Variety A. of the Sandwich Tern, in La- 
tHam’s Index Ornithologicus, the Sterna Nevia of 
GMELIN, and the Guifette of Burron.

been confounded with the Sterna Boysit of Dr Laruam), we 
owe to the discrimination of Monracu, who has pointed out 
its distinguishing characters, and given a figure of it in the 
Supplement to his Ornithological Dictionary. From the 
specific name of Anglica (rather inappropriately imposed by 
this author), it might be supposed a common and generally 
distributed bird throughout this country ; but it is, on the 
contrary, one of our rarest species, and has hitherto been 
only occasionally met with on the southern coast of the king- 
dom, and never in any number together. In its habits it 
approaches nearer to the Black Tern than to the oceanic 
species previously described, preferring the lakes and rivers
