Razor-bill. 



Like the Guillemot, the Razor-bill breeds upon high rocks, 

 and, like it^ lays only one egg ; it has, as I have before sta- 

 ted, often been confounded with white varieties of the eggs of 

 the Guillemot, from them it is, however, very readily known, 

 as the plate will show ; it is less, much shorter, and rounded 

 at the smaller end, and is less apt to vary and run into the 

 same curious varieties. The egg figured is of an intermediate 

 size. The Razor-bill breeds abundantly at Flambro' Head, 

 on the Western islands, the Orkneys, and the Shetland is- 

 lands.
