 and a roundish spot of the same on each side of the rump. Lores, suiierciliary stripe extending 

 back nearly to the occiput, with lateral and under parts of the head generally, bright sulphury- 

 buff, cros.sed by a wide stripe of blackish l)rowu extending from the occiput forward to the eye ; 

 remaining lower parts dingy white, the sides brownish, this crossed on the flanks by an indistinct 

 whitish bur.* 



^ There is in this species a very strange and probalily altogetlier peculiar arrangement of the tertials, 

 longer scapulars, and inner secondaries, both as to form and colors. Tlie exposed surface of the first 

 appears continuously Intense black, as described above ; but upon lifting the feathers it is seen that 

 between each two there is a concealed one of different form and color — narrow and pointed, instead of 

 broad and nearly truncated, and dull bronzy, instead of deep black. Of these bronzy feathers, only tlie 

 last (or the longest scapular) has its tip exposed ; the innermost secondary is tlie longest, and is entirely 

 intense black to the tip ; the next is very nuicli (nearly an inch) shorter, entirely concealed, and also 

 wholly black ; the third is little, if any, shorter than the first, but is marked at the end by a broad bar of 

 pure white ; the fourth is a little shorter, without any white at the tip, and the outer web cliiefly reiklish 

 purple ; this, like the third, has the outer web much widened terminally.
