from the male described in having the hind neck up to the occiput 

 uniform black. It was killed in January, but is evidently in full 

 summer plumage. 



The female described is an Oaxaca skin from the Sclater collection, 

 and is apparently fully adult, though the overlying yellow on the 

 black throat may be a sign of remains of winter plumage. One 

 killed in January at La Parada, in Mexico, has the whole under 

 surface creamy white, but the throat is washed with yellow like the 

 cheeks. The black on the throat is distinctly traceable, the bases 

 of all the feathers being visible beneath the white or yellow tips. 



In a skin obtained by Mr. Salvin at Alotepeque, in Guatemala 

 (mus. Saluiii and Godman), the plumage is like that of the females 

 above described, but the sides of the body are narrowly streaked 

 with blackish. Dr. Cones speaks of these lateral streaks as being 

 present in the young birds. In the specimen in question the black 

 on the throat is nearly hidden by the whitish edges to the feathers, 

 and the black mottlings on the back are beginning to show, so that 

 the specimen is evidently commencing to acquire its full summer 

 plumage. Another specimen in the Salvin-and-Godman collection, 

 killed on the Volcan de Fuego, in Guatemala, on the 20th of 

 November, is nearly fuU-plumaged, but has some yellow margins 

 still discernible on the feathers of the throat. It would appear 

 from this that, even if the full plumage is ultimately gained by a 

 spring moult, the edges to the black feathers of the throat become 

 abraded as early in the year as November, and many specimens must 

 have the full plumage of the adults by December and January, as the 

 bird above mentioned has also nearly lost the blackish tips to the 

 feathers of the crown. The fuU sequence of plumage is not clear to 

 me, as the series of skins examined has been somewhat limited. 



Tounr/. Upper parts olivaceous ash, and the yellow of the top of 

 the head overlaid with olive ; sides of the head pretty clear yellow, 

 fading gradually into the white of the throat; no black on the 

 latter ; white of the underparts faintly brownish tinged, and sides 

 with obsolete streaks. (Ooues.)
