 This  Gull  is  an  irregular  winter  visitor  to  the  coasts  
 of  the  British  Islands ;  but, so far  as I  am  able  to  
 ascertain from  the  standard  authorities,  has  not  hitherto  
 been  found  breeding  in  any  part of  Europe.  It  winters  
 in  Iceland ;  but,  according  to  Mr.  H.  Saunders,  it  
 appears  to  be  confined  during  the  breeding-season  to  
 Greenland  and  the  Arctic  regions of  America.  As I  
 have  never  met  with  this  species alive, I  will  merely  add  
 that  it  closely  resembles  the  Glaucous  Gull  in  its different  
 stages of  plumage,  but  is  considerably  smaller  
 and  less  robust  in " make,"  with  proportionately  longer  
 wings  than  that  bird.
