HABITS OF geace's wakbler 293 



the color of the back, and streaked with black in continuation of the chain 

 of shorter streaks along the side of the neck. Wings dusky, with very nar- 

 row whitish edging, and crossed with two white bars along the ends of the 

 greater and median coverts. Tail like the wings ; the lateral feather mostly 

 white, excepting the outer web ; the next two or three with white blotches, 

 decreasing in size. Eyes, bill, and feet black ; soles dirty yellowish. Length, 

 4iV5i ; extent about 8 ; wing, 2f ; tail, 2i. 



$ , in autumn : Color of the upper parts obscured with a shade of brown- 

 ish-olive, the dorsal streaks obscure. The head-markings as in summer, and 

 the yellow parts quite as bright. 



$ : Quite similar to the male, and in fact scarcely distinguishable from the 

 male in autumn, though the yellow is not quite so strong. 



Young : The slate-gray of th« upper parts much shaded with brownish- 

 olive, the black streaks wanting on the back, those on the crown obsolete. 

 Yellow much as in the adult but paler, and not bordered along the sides of 

 the neck with black streaks. The black lores are poorly defined. The wing- 

 bars are grayish or obsolete. The white of the under parts has an ochrey 

 tinge, and the lateral streaks are not so heavy in color nor so well defined. 



Since this species was originally described, a slight variety {decora) has 

 been noted from Honduras, in which the superciliary stripe is wholly yellow 

 and does not pass beyond the eye, and there are some other slight charac- 

 ters. Among United States species, the present is most like D. dominica, but 

 this is much larger, with a much longer and stouter bill, the long white su- 

 perciliary line prolonged to the side of the neck, where it enlarges into a 

 spot, and the sides of the head and neck broadly black, isolating the white 

 lower eyelid, and otherwise different. 



GRACE'S Warbler is to me a bird of particular and not 

 unpardonable interest, being the only species of this 

 beautiful genus that it has fallen to my lot to discover, and 

 bearing the name of one for whom my affection and respect 

 keep pace with my appreciation of true loveliness of character. 



It is one of the latest additions to the long and varied list of 

 Wood- Warblers, and the only species with which the genus has 

 been enriched during the last ten or twelve years — a near rela- 

 tive of Adelaide's Warbler* from Porto Eico, described at the 

 same time by Professor Baird, and next most closely related to 

 the very old species now usually called Dendrceca dominica. 



In my original notice of this bird, I referred to certain speci- 

 mens collected by Mr. 0. Wood, at Belize, British Honduras, 



* A near relative of D. graciw is the following Porto Eican species, described 

 at the same time by Baird : —
