Toung Male. Similar, not so black, tlie yellowisli-green edges of the feathers of the back 

 broader and extending to the crown of head ; lower parts pale lemon-yellow ; a small 

 elongated shaft-spot on the two longest under tail-coverts. 



Female. Above dull blackish-brown ; darker on the chin and throat, the feathers of back 

 more or less broadly edged with yellowish-green ; margins of tertials, speculum and centre 

 of abdomen very pale yellow, inclioing to white ; rest of under-parts and rump pale lemon- 

 yellow ; two blackish elongated shaft-spots on the under tail-coverts : bill and legs as in 

 the male. 



Ohserv. The very young birds are almost green above, the forehead and chin blackish ; 

 the broad yellow margins of the tertials and secondaries in many specimens of various 

 are completely frayed away. 



This very interesting species, which is so closely allied to Chrysoniitris 

 atraia^ was first made known to science by Dr. P. L. Sclater in his 

 ' Catalogue of American Birds' published in 1862, although well known 

 to ornithologists prior to this date, it was not recognized as different 

 from the young birds or females of Ch. atrata. 



I have a specimen from Mr. Eyton's collection which must have been 

 procured long before 1856, this example (an adult male) was still 

 undetermined when it passed into my collection, and without doubt is one 

 of Mr. T. Bridge's specimens obtained in Chili, as I have one of his skins 

 of Chrysoniitris atrata which is prepared in the same manner. 



Mr. J. Cassin also places this species (which was collected during 

 ' Gilliss's Expedition') under Ch. atrata, he says — " This httle bird is stated 

 to appear occasionally in flocks, though it probably visits Chili only in the 

 season of migration : " but in the ' Proc. Acad. Philad.' 1865, he remarks 

 that the "specimens from ' Gilliss's Exped. to Chili,' now in the National 

 Museum, were mistaken by me for the preceding fC. atratus,) having at 

 that time only the young specimen from D'Orbigny's collection, to which 

 I above alluded, and relying on it for my determination of the species." 



Dr. E. A. Philippi tells us that it " is known in the province of 

 Santiago by the name of Jilguero de la Cordillera, and lives in the central 

 Mountainous provinces extending its range into Peru."
