1866, "Our Summer Migrants," 1875, pp. 97-99, 

 and Seebohm, " Field Notes on the Reed and Marsh 

 Warblers," Zool, 1880, p. 377. It has been 

 identified, and even found nesting, in Cambridge- 

 shire, Oxfordshire {Zool, 1892, p. 303; 1893, 

 p. 308), Middlesex, Somersetshire {ZooL, 1875, 

 p. 4713; 1882, p. 265; 1889, p. 450), and Notting- 

 hamshire (Zool, 1892, p. 332). Blyth detected this 

 bird in several localities near London, and distin- 

 guished the song of the two species (Field, May 13, 

 1871). His observations have been confirmed by 

 Bond, Mitford, and myself. (See Yarrell, " Brit. 

 Birds," 4th ed., vol. i. pp. 373-374.)

 nest also difi'ers in being less deep, not entirely 

 suspended, and -svith no support at the bottom, as 

 is the case with the Reed Warbler.

A summer migrant, generally distributed. May 

 be known at a glance from the Reed and Marsh 

 Warblers by its having the top of the head and 

 wing coverts streaked instead of plain, while the 

 Aquatic Warbler, to be noticed in Part II., which 

 also has a streaked head, has the distinguishing 

 mark of a white central stripe between the two 

 white ear-stripes. The nest, instead of being sus-
