Specimens from the Youkon seem to show traces of hybriility with 

 perenrina, one skin cspeeially (2?, 326) in which tlie checks mid 

 foreiiead are as pure gray as in perecjrina, while all the other char- 

 iicters are those of ce lata. This same apparent tendency to iiybrid- 

 isni ill Youkon specimens is seen in other species, as between Junvo 

 hyemalia and oregonu», etc., and may be explained by the fact of tliis 

 region being in the boundary line of the breeding grounds of these 

 closely allied representative species. 



A specimen of celata, from Georgia, shows no trace of orange in 

 the crown, and is much darker in color, and with larger bill than in 

 western ones. 



Mr. Audubon speaks of the K celata as being common and gener- 

 ally distributed through the Eastern States, and breedinii;- abundantly 

 in Maine, New Brunswick, etc. I have myself never seen or heard 

 jf any specimens from east of the Mississippi Valley, excepting a 

 few taken in Georgia and Florida, and near Philadelphia, and these 

 may belong to a different species. The Institution possesses one 

 specimen from Dane Co., Wisconsin. 



Specimens are in the collection from many localities in the Pacific 

 region of the United States up to the northern boundary, and east 

 to the Rocky Mts.
