Phylloscopus burmanicus, N. Sp. 



The first example of this bird I received from Mr. Oates 

 without any name on the label, about May 1880, and the 

 second example I found in Mr. Hume's museum, labelled P. 

 viridanus. These two accord so perfectly, and differ so decided- 

 ly from all others with which I am acquainted, that I have 

 no hesitation in concluding them to be specifically distinct. 



The upper surface is pale olive as in viridanus ; there is a 

 broad yellowish white supercilium, and the usual brownish band 

 through the eye ; lower surface albescent as in viridanus, and 

 tinged in the same way with dusky or grey on sides of breast 

 and flauks; centre of lower parts faintly tinged with yellow, 

 to the same extent as in viridanus ; upper surface of bill light 

 brown; lower mandible horny white. There is a very conspi- 

 cuous wing bar of the same character as in plumbeitarsus, but 

 no second or upper bar is visible as in that species. 



The first primary is of moderate size as in plumbeitarsus ; 

 second a trifle longer than the 8th. There is a considerable space 

 between 2ud and tip of wing ; in one example *4, and in the 

 other *36 ; this is about one-tenth longer than in viridanus. 



The date of Mr Oates' example is 15th November ; locality, 

 Pegu. Of Mr Hume's, 12th October; locality, 100 miles north 

 of Moulmein, both are marked as males. 



The Pegu bird has the following particulai's on the label : — 

 <f Length, 4*7 ; expanse, 7'5 ; tail, 1*8 ; wing, 2'4 ; tarsus, '78 ; 

 bill from gape, "59. Iris brown ; lower mandible of bill yellow, 

 dusky at extreme tip ; upper one brovin; legs and toes yellow- 

 ish brown ; claws pale brown." 



The Moulmein bird's wing is 2*37; tail, 1*8; bill, at front, 

 •36 ; from gape, "58 ; tarsus, *78. 



It is one of the broad B?/polais~h\\\ed group, like nitidus, poly- 

 glotta, viridanus, magnirostris, lugubris, plumbeitarsus and 

 others. 



From viridanus it may be distinguished as follows : — 



(1.) The wing bar being abruptly separated from the greenish 

 colour of the rest of the feather, while in viridanus the wing bar
