The differences Ijetween tlie Pacific coast specimens of the H. alofn and 

 those from the interior regions — tirst [)ointed out in the Iteview of Ameri- 

 can Birds — are very readily appreciahle upon a comi)ari.son of specimens. 

 Tlie present bird is a coast variety, entirely replacing the true cduta (var. 

 cclata) iu the region above indicated.

 the tip. Feimth with the ash of the head less conspicuous ; the under partes more tinged 

 with olive-yellow. Length, 4..")0 ; wing, 2.75 ; tail, 1.8o.

Autumnal specimens and young birds are sometimes so strongly tinged 

 with greenish-yellow as to be scarcely distinguisliable from H. cclata. The 

 wing is, however, always longer, and the obscure whitish patch on the 

 inner edge of the exterior tail-feather, near its tip, is almost always a])- 

 precial)le. In cc/ata this edge is very narrowly and unitbrndy margined 

 with whitish. 



A young bird of the year, from Fort Simpson (27,228), has two distinct 

 greenish-white bands on the wings, and the forehead and cheeks greenish- 

 yellow. A con'esponding age of If. cclata has the wing-bands more reddish- 

 browTi, the wings shorter, and no white patch on the outer tail-feather. 



Habits. Like the Nashville Warbler the present species has received a 

 name inappropriate to one with so northern a distribution. It was first ob- 

 tained on the banks of the Cuml)erland Kiver by Wilson, and has since been 

 known as the Tennessee Warbler. But two siX5cimens were ever obtained 

 by him, and he regarded it as a very rare species. He found them hunting
