TjTjJ. Larus melanocephalns. Natt. his, 181S, p. 8 16. Adriatic 

 Gull. 



The Adriatic Gull flits about the coast all winter, but appears to retire 

 to Asia Minor for nidification. 



This bird is almost confined to the Mediterranean and Black Seas. 



338. Larus ichthyaetus. Pall. Reis. Russ. Reichs. ii., App., p. 713. 

 Great Black-headed Gull. 



This royal Sea Gull is to be found on the coast in winter plumage, 

 and later on is frequent on the Sea of Galilee in its full nuptial dress. It 

 is indeed the Eagle of the Gull tribe. But it leaves the lake in May, and 

 where it breeds I know not. 



The Caspian appears to be the headquarters of this Gull, which ranges 

 through Egypt and Nubia, and is found on most of the rivers of 

 India. 



339. Larus canus. Linn. Syst. Nat. i., p. 224. Common Gull. 



Frequent on the coast in winter. 



It ranges through Europe and Asia, as far south as Northern 

 China.

 Slender-billed Gull. 



Occurs on the coast in winter. 



It inhabits South Europe, North Africa, and South-western Asia. 



341. Lams leucop/imis. ((Licht) Bruch., J. F. O., 1853, p. loi, 

 No. 18.) Yellow-legged Herring Gull. 



Common on the coasts. 



This bird is almost confined to the Eastern Mediterranean. 



342. Larus argentahts. Gmel. Syst. Nat. i., p. 600. Herring 

 Gull. 



I obtained this bird off Tyre. It appears to be not rare in winter, 

 but not so common as the yellow-legged species.
