^ Eight specimens. 



'•^Five specimens. 



^ A nest and eggs, with the female parent, collected at Banff in June, 1898, were sent 

 to me for identification by IMr. Charles E. Doe, of Providence, R. I. 



* All these supposed records from east of the Missouri River are more or less doubt- 

 ful, except that pertaining to Laurel, Maryland, which alone has been seen by me 

 since the present form was differentiated. Some of them — possibly all — may be 

 referable to /. oreganus shufeldti 



■'Many of the records queried above may belong to J. oreganus sJnifeldli, but not 

 having seen the specimens on which they are based, I have thought best to place 

 them under /. viontanus provisionally.
