 in tinge, the underparts whiter, and the second quill is longer than the fourth ; legs pale flesh-colour 

 with a brownish tinge ; beak as in A. streperus; iris dark brown. Total length about 5'5 inches, 

 culmen 0'62, wing 28, tail 2'3, tarsus O9o.

The Marsh- Warbler inhabits Continental Europe during the summer, migrating southward into 

 North Africa during winter, and is found in Asia as far east as Persia. 



According to Mr. J. E. Harting it has occurred at least six times in Enoland ; but Professor 

 Newton says, in his new edition of Yarrell's ' British Birds,' that, as it is so difficult to distinguish 

 between prepared specimens of the two species, he considers it premature to admit A. palustris
