LENGTH thirteen inches. Bill dusky brown ; crown, nape, 

 and all the upper parts of the plumage, wings, and tail, with the 

 edges of the under coverts and thighs, black ; beneath wholly white, 

 the black and white mixing on the sides of the neck ; legs brown, 

 webs yellowish. 



Inhabits the Isle of Man, Saint Kilda, the Orknies, and all the 

 northern coasts of England ; also Ireland ; frequent in Norway and 

 Denmark. Has been met with on the coasts of France, and Holland, 

 but the instances are rare. Said to breed in the holes of rocks, or 

 old rabbit burrows, and to lay a single white egg, about the size of 

 that of a Duck. 



I have for some time been aware of the probability of the birds 

 called Shearwaters forming at least two distinct species, arising 

 from my having received two birds of this kind from Mr. Walcot, in 

 the year 1792 ; one of which was more than sixteen inches in length, 

 and thirty-three in breadth, and weighing seventeen ounces; the bill 

 black, with reddish brown sides ; nostrils swelling, but not distinct, 

 arising out of an eminence, but not bony ; plumage above dusky 

 black ; beneath more or less dirty white, clouded with ash-colour ; 

 tail of twelve feathers, dusky black. The other only twelve inches 

 long, twenty-six broad, and weighed ten ounces and a half; as to 

 plumage it chiefly differed, in the under parts being wholly white; 

 tail as in the other, but the outer feather (on one side only) was 

 wholly white.
