of the United States, and less regularly on the Great Lakes and 

 larger rivers of the interior ; south to Mexico and Lower California. 

 In Missouri the Butterball is a fairly common transient visitant 

 in early spring and late fall. It is sometimes taken in February, 

 even in the western and northern part of the state (February 5, 

 1904, Kansas City, Bryant; February 22, 1885, Keokuk, Prae- 

 ger), but small troops are met with most frequently between 

 March 1 and April 10, exceptionally later (May 4, 1892, Keokuk, 

 Currier). In fall the earliest record is October 10, 1904, (Kansas 

 City, Bryant) and the latest December 4, 1892 (Keokuk, Currier) . 

 The largest number of dates were obtained between October 10 

 and November 20.
