COUES ON BIRDS OF DAKOTA AND MONTANA. 577 



OARPODACUS PURPUREUS, {Gm.) Gray. 



Purple Finch. 



This species was found in small numbers on Turtle Mountain during 

 the latter part of July. It doubtless breeds in this locality. It has been 

 traced by other observers as far as the region of the Saskatchewan, but 

 I did not find it in the Rocky Mountains, nor, indeed, anywhere along 

 the Line, excepting in the locality just mentioned. In the Missouri re- 

 gion, I have ascertained that it ascends the river as far at least as Port 

 Randall, — how much further I am unable to say ; the evidence of its 

 presence above that point being negative, with the exception of Dr. 

 Hayden's record of a specimen from Vermilion River. 



List of specimens. 



CHRYSOMITRIS TRISTIS, {Linn.) Bp. 

 American (tOldfinch. 



This familiar bird was noted only at Pembina. It is, however, a 

 species of general distribution in North America, so that the lack of 

 observation respecting it at other points is to be regarded as simply 

 fortuitous. 



While upon the small subgroup of the FringilUdce to which the 

 Ijresent species belongs, I may properly note some other kinds which 

 undoubtedly belong to the avifauna of the Boundary Line, though they 

 escaped my observation. These are chiefly winter visitors from the 

 north, — for it will be remembered that I was in the field, during both 

 seasons, only from June to October. 



The Pine Grosbeak, Finicola emccleator, the two Cross-bills, Loxia, 

 americana and L. leucoptera, the Gray-crowned finch, Leucosticte tephro- 

 cotis, and the Red-poll Linnet, ^giothus linaria, all enter this country 

 later in the fall, some to remain during winter, others to pass further 

 on ; while the Pine Linnet, Chrysomitris pinus, is a species of the same 

 general distribution as the Goldfinch. 



Of the genus Plectrophanns, next to be considered, all the Kortb 

 American species occur in this region, which is the very home of two ot 

 them 5 two others came southward just as I was leaving, the 1st of Oc- 

 tober ; and the fifth, the Snow Bunting, P. nivalis, which was the only 

 one not seen, doubtless came along shortly afterward.
