Townsend's Warbler. Somewhat similar to virens; upper jiarts olive- 

 green, much black-streaked, crowu mostly black with olive edgings of the 

 feathers, chin and throat not perfectly black? Perfect plumage probably 

 not known, and changes not well understood. Rocky Mountains to the 

 Pacific; said to have once occurred near Philadelphia. Nutt., 2d ed., i,

Golden - cheehed Warbler. Prevailing color of the upper jiarts black, 

 pure on the rump, elsewhere mixed with olive-green ; sides of the head 

 yellow, with narrow black stripe through the eye ; below, with the wings 

 and tail, as in virens; size of this species. Guatemala (JSalvin) to Texas 

 (San Antonio, Heennarm). A species I have never seen ; the description is 

 abridged from Baied, Eev., 183, 267, who took it from the tyjie of the 

 species. Scl. and Salv., Proc. Zool. Soc. London, 1860, 298, and Ibis, 

 1860, 273. * ^* This and the two preceding species require further investi- 

 gation to place their relationship to each other and to virens upon firm 



footing CHUYSOPAEEIA. 



ij"* Blaeh-ilircated Gray Warbler. $, in spring: back bluish-ash, with 

 black streaks ; head and neck all round pure black, with a white stripe over 

 and behind eye, another, broader and longer, from the corner of the bill 

 on each side of the chin and throat, and a little yellow spot just before and 

 above the eye (no other j'ellow anywhere) ; below 

 frcmi the throat white, the sides with numerous black 

 streaks ; wings and tail blackish, former with two 

 white bars and much whitish edging, latter wath outer 

 feathers almost entirely white ; bill and feet black. 

 Young, and 9 , differ chiefly in having the black of 

 the head and throat clouded with ashy, and the black 

 streaks of the back obsolete : the curious yellow loral 

 spot seems to be persistent and diagnostic of the species. Size of virens, 

 and much the same pattern of coloration, bluish-ash replacing the olive ; 

 stands between virens and coirulescens ; the western aualogue of the latter.

 wardly edged with bluish, the inner ones mostly white on their inner webs; 

 tail with the ordinary white blotches, the central feathers edged with
