SYLVICOLID.E — THE WARBLERS. 205 



a brownish tinge above ; middle and secondary coverts tipped with dull fulvous, furry, in- 

 conspicuous bands. No trace of orange on the crown. 



IIab. Paeilic Province of North America, from Alaska to Cape St. Lucas. Straggling 

 eastward to about the 116th meridian. Not found in Mexico? 



The differences between the Pacific coast specimens of tlie H. celata and 

 those from tlie interior regions — first pointed out in tlie Review of Ameri- 

 can Birds — are very readily appreciable upon a comparison of specimens. 

 The |)resent bird is a coast variety, entirely replacing the true cdata (var. 

 celata) in the region above indicated.

Sp. Char. Top and sides of the head and neck ash-gray ; rest of upper parts olive- 

 green, brightest on the rump. Beneath dull white, faintly tinged in places, especially on 

 the sides, with yellowish-olive. Eyelids and a stripe over the eye whitish ; a dusky lino 

 from the eye to the bill. Outer tail-feather with a white spot along the inner edge near 

 the tip. Female with the ash of the head less conspicuous ; the under parts more tinged 

 with olive-yellow. Length, 4.50; wing, 2.75; tail, 1.85.

Autumnal specimens and young birds are sometimes so strongly tinged 

 with greenish-yellow as to be scarcely distinguishable from IT. celata. The 

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

 inner edge of the exterior tail-feather, near its tip, is almost always ap- 

 preciable. In celata this edge is very narrowly and uniforndy 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 corresponding age of If. celata has the wing-bands more reddish- 

 brown, 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 Cumberland liiver by Wilson, and has since been 

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

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