MOURNING WARBLER. 79 



mented with a singular crescent of alternate transverse lines of pure 

 glossy white, and very deep black ; all the rest of the lower parts are 

 of a brilliant yellow ; the tail is rounded at the end ; legs and feet, a 

 pale flesh-coloiu" ; bill brownish- black above, lighter below ; eye hazel.'" 

 This single bird, thus procured and described, was supposed by 

 some to be merely a variety of another species. But several indivi- 

 duals have been found since, and I have in my possession two males, 

 presented to me by Mr Harris, who procured them near Philadelphia, 

 This species I have not represented in my Illustrations, having at first 

 conceived it to be identical with the specimens from the Columbia 

 River ; but its description may here be introduced with propriety.
