4. First Nuptial Plumage acquired by wear which produces 

 Httle change except to expose the concealed yellow of the crown 

 by loss of the greenish feather tips. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult in July. Practically indistinguishable from first 

 winter dress, the yellow of the crown rather more conspicuous 

 and the yellow below a trifle deeper. 



6. Adult Nuptial Plumage acquired by wear as in the 

 young bird. 



Female. — Indistinguishable from the male in juvenal plumage ; 

 in later plumages distinguished by the duller black of the trans- 

 ocular streak and by very little yellow on the crown. 



I am able to throw little additional light on the supposed hy- 

 brids H. leiicobroitcJiialis and H. lazurencei. Of two specimens 

 in my collection from the same brood and fed by a typical H. 

 pinuson^ (No. 4434, 9 , June 28th, New Jersey) is in the juvenal 

 dress of this species with many new yellow feathers of the first 

 winter plumage appearing, the other (No. 4433, (?), is in similar 

 juvenal dress, but is acquiring on the throat the black feathers of 

 H. lazvrencei. 



Helmmthophila chrysoptera (Linn.). Golden-winged 



Warbler 



1. Natal Dow^n. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult.

 with bluish plumbeous gray, the coverts and tertiaries with olive-green. Below, 

 pale olive-yellow, the throat dusky. Transocular stieak dusky. Bill and feet 

 pinkish buff becoming dusky. 



3. First Winter Plumage acquired by a partial postjuvenal 

 moult, beginning early in July, which involves the body plumage 

 and wing coverts, but not the rest of the wings nor the tail, 

 young and old becoming practically indistinguishable. 



Unlike previous plumage. Above, plumbeous gray veiled with olive-green edg- 

 ings ; the crown bright lemon-yellow veiled posteriorly only. Below, 

 grayish white, with yellow edgings here and there, the chin, jugulum, lores
