BLACK GUILLEMOT. Crass II. 
land ; in the isle of St. Kilda; and, as Mr. Ray 
imagines, in the Farn islands off the coast of 
Northumberland; we have also seen it on the 
rocks of Llandudno in Caernarvonshire, and on 
islets S. W. of Anglesey, near Lilanddwyn, 
where it breeds. Except at breeding time, it 
keeps always at sea; and is very difficult to be 
shot, diving at the flash of the pan. The Welsh 
call this bird cas gan longwr, or the sailor’s 
hatred, from a notion that its appearance fore- 
bodes a storm. It visits St. Kilda’s in March; 
makes its nest far under ground, and lays a grey 
egg, or, as Steller says, whitish spotted. with 
rust, and speckled with ash-color.
