Ad. corpore supra fusees centi-olivaceo vix viridi tincto, uropygio sulfureo lavato : alis et cauda, saturate schis- 

 taceo-fuscis, pluruis extiis anguste viridi marginatis : stria superciliari pallide flavescenti-cervina, : 

 corpore subtus albo, pectore et hypochondriis vix sulfureo tinctis : axillaribus et margine alae lrete 

 sulfureis. 



Adult Female (Piedmont, 20th April). Upper parts much browner than in Ph. sibilatrix, being brownish 

 olive with a greenish tinge, the rump washed with sulphur-yellow ; wings and tail slaty brown, with 

 very narrow dull greenish margins ; streak over the eye light buffy yellow ; underparts white, with a 

 light sulphur-yellow tinge on the breast and flanks; axillaries and edge of the wing bright sidphur- 

 yellow. Total length about 4'75 inches, culmen - 42, wing 2 - 5, tail 1'82, tarsus 0'72; first primary 

 longer than in the Wood- Wren, being 1 - 1 shorter than the second , which is 02 less than the third, and 

 a trifle longer than the sixth, the third and fourth nearly equal, the fifth a trifle shorter. 



Adult Male. Similar in plumage to the female, but a trifle larger, measuring — culmen 0"42, wing 2 - 7, 

 tail 2 - l, tarsus 072. 



Obs. In the series of specimens I have of this bird I find a good deal of difference in coloration, some 

 having the upper parts much browner and the underparts much whiter than in others ; and most of 

 those from Greece and North Africa have the underparts white without any trace of yellow, except on 

 the flanks, and the eye-streak buff. This being the form usually figured, I have deemed it advisable to
