sides and crissum ; the breast and sides of the abdomen thickly marked 

 with rounded spots of clear brown. 



The series of adults is a very full one and includes several interest- 

 ing styles of plumage. Some of the males have the brown of the 

 back mixed with ashy, which has a tendency to form a collar on the 

 nape, and gives the interscapular region a patched appearance. In others 

 the red of the under parts as well as that of the crown is replaced 

 by orange ; while one specimen has a large patch of lemon-yellow on the 

 right side of the breast, which shows in striking contrast with the other- 

 wise clear carmine of the lower surface. These variations present a 

 curious analogy to certain similar ones which occur in the Scarlet 

 Tanager and Summer Red-bird.
