4. First Nuptial Plumage acquired by wear which produces 

 little 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 Jul}'. Practically indistinguishable from first 

 winter dress, the yellow of the crown rather more conspicuous 

 and the }'ellow below a trifle deeper.

 young bird.

 ocular streak and by very little yellow on the crown. 



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

 H. lazvroicci.

3. First Wixter Plumage acquired by a partial postjuvenal 



moult, beginning early in Jul)-, 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
