South coast of Spain, the Mediterranean and Black Sea (breeding); the Red Sea, Persian Gulf, and the coasts as far as Kurrachi; also West Africa to Senegal, whence there is a specimen in the Paris Museum. This species seems to have no very near allies. It never has a hood ; yet its structure and wing-pattern remind us of L. ridibundus. In appearance it is like L. scopulinus; but its wings are very long, its bill is slender, its flight is Tern-like, and its eggs are singularly like those of Sterna cantiaca and S. media. I locate it here because I do not know of any better position for it. 31. LARUS LEUCOPHTHALMUS, Licht. Larus leucophthalmus, Licht.; Temm. Pl. Col. liv. 62, pl. 366 (1825); id.

Temminck states that this species visits Greece and the shores of the Bosphorus; but no recent travellers in those parts have ever met with it; and although two energetic naturalists, Dr. Kriiper and M . Alleon, have for years been resident in the neighbourhood and have thoroughly explored the Greek Archipelago and the Bosphorus, they have never met with it, either there or in the Eubcean channel, which Lindermayer (Vog. Griech. p. 177) so particularly indicates. Even in the Red Sea it is, according to Von Heuglin, very scarce north of the tropic, though frequent more to the_south ; it does not, however, appear to go beyond the Gulf of Aden and the Somali coast; for neither Blanford nor H u m e mention it as occurring along the Mekran coast; and its range is therefore much less extensive than that of the allied species L. hemprichi. 32.
