Hub. 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 

 m the Pans 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 lono- its 

 bill is slender, its flight is Tern-like, and its eggs are sing'ularl/'like 

 those of Sterna cantiaca and S. media. I locate it here because I 

 do not know of any better position for it.

 Hab. 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 neighbour- 

 hood 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 (A'og. Griech. p. 177) so particularly 

 indicates. Even in the Red Sea it is, according to Von Heu<*lin, 

 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 Hume mention it as occurring 

 along the Mekran coast ; and its range is therefore much less exten- 

 sive than that of the allied species L. hemprichi.
