Remarlcs. — The only species with which it seems necessary to 

 make comparison is, 0. gratiosa, Sclater. The wings are shorter 

 and the tail is longer than in that species, the hill is larger and 

 the under mandible is pale in color, instead of brown ; in their 

 upper plumage they are somewhat alike, but gratiosa has the 

 back ruddy-brown, in the other it is greenish-olive ; the under 

 plumage of gratiosa has a general yellowish cast, huffy on the 

 abdomen, whereas in the new species, the yellow is restricted to 

 the abdomen, and is a clear pale yellow ; the tail of the new 

 species is light brown, that of gratiosa blackish-brown.
