Large Gulls are common thronghout the Azores, and we met with them on 

 everj- island, and saw specimens in every intermediate stage of plumage during oni- 

 journeys between the islands. Most of the lakes inside the t'aldeiras were tenanted 

 by one or more pairs of breeding Gulls, and ou the islands of San Jorge and Fayal 

 we met with them at an elevation of at least 3(10(.) ft.] 



"•20. Larus fuscus, i>ale form ! 



? ad. (No. Snfi), Terceira, liOd ft., 4. i v. 1903. "Iris straw-yellow, eyelid 

 vermilion. Bill pale bright yellow, tip of lower mandible carmine-red. Legs 

 bright pale yellow." I have not yet come to a conclusion about the various forms 

 of Larus fuscus, but in any case this example is very pale above. 



[On the Cabras or Goat Islets, off Terceira, we found a large colony of this 

 species, breeding on the ledges near the tops of these curious " stacks."' The nests 

 contained two or three fresh eggs on May 30th. The species was also seen breeding 

 on the rocks between the islands of Pico and Fayal. 



On the Cabras Islets we had an excellent opportunity of observing these birds 

 from above, as they sat on or stood by their nests on the ledges below us. I was 

 at first inclined to believe that the darker-backed birds were examples of /,. fuscus, 

 but I soon satisfied myself that all were of one species, L. carhinniins, and unfor- 

 tunately did not i)rocure specimens.

We saw a flock feeding in company with L. cachinnans on some grass fields 

 above Lameiro on March loth, and observed a certain number of birds on the lake 

 at Furnas, but have no record of having met with the species elsewhere.]
