 BRUNNICH'S GUILLEMOT. 



THE THICK-BILLED GUILLEMOT. 



Uria Brimnichii. 



Brunnich's Guillemot is at once distinguished, at any 

 season of the year, from the Common Guillemot by the 

 shortness, stoutness, angularity, and greater dejith of its 

 bill, and in reference to this peculiarity it has been called 

 the Thick-billed Guillemot : it is also of a much blacker 

 colour on the upper parts. It was first described by Briin- 

 nich, in his ' Ornithologia Borealis ' (p. 27), under the name 

 of Uria troille, and an alteration of the specific term being 

 necessary, the late Sir Edward Sabine named this Guillemot
