The pluuuioe of the adult male, which i.s not as often seen as that of the 

 younger stiiges and adult female, is represented in the Sinitli.sonian Collec- 

 tion by fifteen specimens, from various jiarts of North America. Of tliese, 

 an example from Jamaica exhibits the purest shades of color, though agree- 

 ing closely witli some specimens from the interior of tlii' United States ; the 

 cinereous above being very fine, and of a light bluisli cast. The up])er tail- 

 coverts are tipped witli white ; the tail is a quarter of an inch longer tliun 

 in any North American specimen, one half-inch longer than the average ; 

 the wing, however, is tibout the same.
