Length, 23; wing, 18; tail, 7.50; bill, 24; tarsus, 24. 
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. Onein 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 occidentalis, 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.
