COUES ON BIRDS OF DAKOTA AND MONTANA. 607 



List of specimens. 



OOKVUS CORAX, Linn. 

 Raven. 

 Occasionally observed, but no specimens were secured. 



PICA MELANOLEUCA HUDSONICA, (Sah.) Coues. 

 AMERICAN MAQPIE. 



No Magpies were seen in the Red River region, where, if occurring at 

 all, I doubt their presence as far east as the river itself. During the 

 second season, however, they were very frequently noticed at various 

 points on the Upper Missouri and Milk Rivers, and thence to the Rocky 

 Mountains. On the 1st of July, newly fledged birds were taken near the 

 mouth of Milk River, and at the Sweetgrass Hills, during the first week 

 in August, imperfectly pluraaged individuals, a little over a foot long, 



were noticed.
