resemblance to tlie brown colour of that of the Garden War- 

 bler, which has been frequently called the Greater Petty- 

 chaps, as shown by the synonymes. 



The adult male has the beak dark brown ; the irides 

 brown ; over the eye a light-coloured streak, sometimes ra- 

 ther obscure ; the head, neck, back, wings, and tail-feathers, 

 nearly a uniform ash-brown ; the quill-feathers rather darker 

 than the other parts, the edges of the tertials rather lighter ; 

 the chin, throat, breast, belly, and under tail-coverts, dull 

 brownish Avhite, tinged with yellow ; under wing-coverts 

 primrose-yellow ; under surface of wing and tail-feathers 

 grey ; legs, toes, and claws, dark brown, almost black. 



The whole length of the bird about four inches and three- 

 quarters. From the carpus to the end of the longest primary 

 two inches and three-eighths : the first feather short ; the 

 second about as long as the seventh, and neither of them so 

 long as the fifth or sixth ; the third and fourth nearly equal 

 in length, and the longest in the wing. 



The plumage is similar in the two sexes. Young birds, 

 like the young of the species last described, are more tinted 

 with green and yellow than very adult birds. 



It should be borne in mind, that the British Bird to 

 which the term hippolais has usually been attached in the 

 works of British Naturalists, is not the hippolais of Con- 

 tinental authors ; and before quitting this little group, I 

 may here mention that the Hon. and Rev. W. Herbert, 

 in his notes to a recently published edition of White's 

 Natural History of Selborne, has mentioned two other 

 Warblers ; but as T have never yet been so fortunate as to 

 obtain a specimen of either of them, I only here refer to 

 that gentleman"'s account. I venture respectfully to request 

 to be allowed an opportunity of examining any British War- 

 bler which may be considered to differ from those figured 

 and described in this History of British Birds.
