Hab. South Atlantic (and Gulf ?) States. 



(No. 3,054.) Fourth quill longest ; 3d, and then 5th little shorter ; 2d inter- 

 mediate between 6th and 7th ; 1st about half the lougest. 



Upper parts rather dark plumbeous-ash, almost inappreciably paler on the 

 upper tail coverts ; beneath dull bluish-white, the sides of body pale plumbe- 

 ous, shading insensibly into the whitish of belly ; the axillars, for the most 

 part, almost as dark plumbeous as the back, the outer webs of tbose nearest 

 the wing whitish (the inner wing coverts dark plumbeous, edged with dusky)A 

 In the specimen described (perhaps female) the feathers of jugulum and 

 breast present very obsolete and indistinct waved transverse lines of pal© 

 plumbeous, and some of the upper tail coverts are tipped with blackish. 

 Bristly feathers at side of upper mandible continuous with a broad stripe 

 through and behind the eye to posterior extremity of ear coverts, black. This 

 stripe extends narrowly above and broadly below the eye, aud is not varied 

 on lower eyelid with white. There is no black frontal line, although the 

 black frontal bristles of opposite sides sometimes almost meet. Forehead 

 and side of crown as far as the eyes somewhat hoary, shading into the ash 

 of the head. Outer webs of scapular feathers also whitish, shading into the 

 color of back. Wings black ; the lesser coverts only like the back ; the tips 

 of secondaries, and a distinct patch at base of primaries, white. This patch 

 crosses the bases of all the primaries (indistinct on tbe outer), extending 

 farthest along the middle ones, where it reaches a point but little beyond the 

 middle of the exposed portion of the outer primary. The inner webs of 

 the secondaries are gray or whitish for about half way from the border to the 

 shaft, but not abruptly defined. The tail is black ; the concealed bases of all 

 the feathers, except perhaps the innermost, are white ; the entire terminal 

 third of the outer feather, and still more of its outer web, with a constantly 

 decreasing amount on the succeeding feathers as far as the fourth, white ; the 

 shafts, however, are dusky almost to their extremities. Bill and feet black. 



(No. 3,054.) Total length, 8.50 ; wing, 3.72 ; tail, 4.10, its graduation, .92; 

 exposed portion of 1st primary, 1.76, of 2d, 2.40, of longest (measured from 

 exposed base of 1st primary), 2.75; leugth of bill from forehead, .82, from 

 nostril, .50, along gape, .98, depth, .36; tarsus, 1.00; middle toe and claw, 

 .82, claw alone, .30 ; hind toe and claw, .65, claw alone, .32. 



Of the ten specimens before me nearly all exhibit, to a greater or 

 less extent, the obsolete wavings on the feathers, described above. 

 In several, also, the lesser wing- and upper tail-coverts are^ tipped 

 occasionally with blackish — features not observed in excuhitoroides. 

 There is some variation in amount of white on the tail in No. 542,
