Var. feathers of the throat white. 



We are much inclined to believe that this is no other 

 than the razor-bill, in its different dresses : we have re- 

 ceived them from Orkney at different seasons, and have 

 had them exhibiting every variety which black and white 

 could produce. It is a curious circumstance, that the black 

 feathers of most northern birds change more or less to 

 white in winter, and again assume their original black as 

 spring approaches.

A. rostro compresso-ancipiti sulcato sulcis quatuor, 

 oculorum orbita temporibusque albis 9 palpebra 

 superiors mucronata* 



The bill is compressed, triangular, sharp-pointed, 

 red, at the base grey ; crossed by furrows ; the nos- 

 trils are narrow ; the corners of the mouth are 

 puckered ; the eye-lids are callous, edges crimson; 

 the irides are grey ; the whole upper parts and collar 

 black ; the chin, chest and belly are white ; the legs 



are orange. 



The puffin is migratory and arrives about April 

 on the coast. 



She deposits her egg in a hole in the sand, and is 

 assisted by her mate in the hatching.
