COUES ON BIRDS OF DAKOTA AND MONTANA. 617 



MELANEEPES ERYTnEOCEPHALUS, {Linn.) Sw. 



Eedheaded Woodpecker. 



Coiniuon along the Eed and Upper Missouri Eivers. It probably 

 extends, in suitable places, to the Eocky Mountains, but was not noticed 

 after leaving the vicinity of the Missouri, as there is not wood enough 

 to attract it along the affluents of the Milk Eiver on the parallel of 4yo. 



List of s^yecimens. 



ASTN^DESMUS TORQUATUS, {Wils.) Coues. 



Lewis's Woodpecker. 



While we were encamped on one of the headwaters of the Saskatche- 

 wan, at the eastern base of the mountains, a Lewis's Woodpecker flew^ 

 overhead, and was distinctly recognized both by Mr. Batty and myself. 

 At our permanent camp on Chief Mountain Lake, we confidently ex- 

 pected to see the species again and secure specimens, but in this we 

 were disappointed, for not a single one was encountered in our excursions 

 in the vicinity. 



COLAPTES AUEATUS, (Linn.) Sw. 



GOLDEN-WINOED WOODPECKER. 



Flickers were common along the Eed and Mouse Eivers, and were 

 also observed at Pembina and Turtle Mountains, which is equivalent to 

 saying that the species inhabits the wooded portions of the Eed Eiver 

 watershed. All the specimens secured were pure auratus^ without a 

 touch of mexicunus, and the mixed race probably does not occur in this 

 region. This is another evidence of the distinction, which I continually 

 insist upon, between the watersheds of the two great rivers.
