(No. 34,676, 9 •) Very similar to A. cyanoleuca, of Brazil, in color and size, 

 although rather smaller, except that the tail is more deeply forked (.60 deep, 

 instead of .45) ; the bill larger, broader, and more depressed (from nostril 

 .18, instead of .16) ; the sides of the body under the wings blackish, with 

 slight steel blue gloss (in true cyanoleuca merely brownish dusky, without 

 gloss). Upper parts glossed with violet, instead of uniform steel blue, having 

 a tinge of greenish. A slight, almost inappreciable wash of rusty yellowish 

 beneath.
