Range in Great Britain. A specimen of a supposed " Dartford 

 Warbler," was procured in St. Kilda on the i3th of June, 1894, 

 by Mr. J. S. Elliott, who sent it to me for identification, and I 

 was not a little surprised to find that it was an example of the 

 present species. 



Range outside the British Islands. Inhabits the countries of the 

 Mediterranean, probably as far east as Persia. Winters in 

 Senegambia, and in North-eastern Africa. 



Habit. Mr. John Whitehead, who observed this species in 

 Corsica, says that it is plentiful in that island, arriving about 

 the middle of April. The first nest was taken on the 6th of 

 May. He writes : " This little warbler spends nearly all its 

 time in the thick scrub, sometimes mounting high into the air, 

 and uttering a short but pretty song, then diving back into the 

 dense bush, its whereabouts being only discovered by a short 

 chattering note." 



Nest and Eggs. The same observer describes these as 

 follows : "The nest is often frail, about ij inch deep and 2j 

 inches in diameter. It is composed of dry stalks, often 

 with a good many dead thistle-leaves, and lined with fine dry 

 grass, sometimes with long horse-hairs. The eggs, four in 

 number, are of a pale yellowish or greenish- white, speckled all 

 over, but especially at the larger end, with light brown and 

 slate blue."
