Hab. — Northwest Europe; Baltic; western coasts down to North Af- 

 rica; Azores; Madeira; Canaries; Greenland; Hudson's Bay; Labrador; 

 down the coast as far as Texas ; Cuba ; Bermuda. (Saunders.) 



These Gulls occur frequently, not regularly, and many specimens 

 have been obtained. One in my collection was shot in Devonshire Bay 

 on the 4th November, and they have been seen as late as the 19th 

 March. They were numerous in the autumn of 1875, and Lieutenant 

 Denison obtained several specimens, all immature. 



Larus occidentalism Aud., has been included in the Bermuda lists by 

 Colonel Wedderburn (Nat. in B., -p. 54), but I think the geographical 

 distribution of this species [Pacific Coast of North America (Saunders), 

 (Coues)] precludes all possibility of its having occurred in the islands.
