largest. Tail considerably graduated and less emarginated, the middle 

 pair being equal to the 2d pair from the outside ; tail-feathers a little 

 shorter than wing. 



Upper surface pure slaty -plumbeons, forehead slightly washed with 

 olivaceous; lores black; also a stripe below the white patch on the under 

 eyelid, assuming the color of the back on the ear-coverts, each feather 

 of which and the above-mentioned stripe having a narrow, well-defined 

 white central streak behind, very faintly washed with brownish. From 

 the base of lower mandible a well-defined malar stripe runs backwards, 

 the anterior third of which is white, while the lower two-thirds have the 

 color of the throat, from which the malar stripe is separated by a narrow, 

 but distinct, black stripe, reaching close to the lower edge of the mandi- 

 ble. Throat and chin chestnut-rufous, the white bases of the feathers 

 on the latter showing somewhat through. Breast and upper sides of 

 abdomen lighter than the back, almost clear ash-gray, becoming gradu- 

 ally lighter towards the abdomen ; remaining underparts of the same 

 color as the throat, only somewhat paler, and assuming a faint oliva- 

 ceous shade on the upper abdomen ; tibia like the back, a few feath- 

 ers being tipped with rufous. Wings blackish, with pale edges on 

 the primaries and two ash-gray bars across the secondaries, leaving 

 between them a deep black patch; wing-coverts, except the primary 

 coverts, broadly edged with gray like the baclv ; innermost secondaries 

 almost entirely so ; inner web of the quills white at the base, forming a 

 broad bar on the under surface of the wing ; edge of wing grayish white. 

 Middle tail-feathers uniform slate-gray ; the following pairs black, the 

 three outmost with a wedge-shaped white spot on the inner web at the 

 end, making on the innermost only one-fifth of the length of the quill, 

 on the middle one about one-half, and on the outerinost about two-thirds, 

 the outer webs being light slate-gray for the same extent from the tip. 

 Bill black ; legs pale brownish yellow. 



The female seem to differ from the male in having the gray color of 

 the breast less pure, this part being somewhat suffused with rufous-olive. 



A young bird in the collection of Mr. Geo. N. Lawrence {Martinique, 

 July, 1877, F. A. Ober), which has begun to assume the adult plumage, 

 has the underparts dull orange-rufous, each feather with blackish edges, 

 except on the throat and under tail- coverts, which are almost unicolor; 

 upper parts and small wing-coverts much darker, with small rufous 

 spots before the black terminal edge; greater and middle wing-coverts 

 edged at the tip with rufous. Wing-feathers elsewhere and tail almost 

 identical with the same parts in the adults.
