belonging exclusively here, even if its earlier exclusive use in this sense he

Geographical distribution. — As will be seen by a reference to the 

 subjoined list of specimens, the present species has quite an extensive geo- 

 graphical range, being found from Pembina, Minn., eastward to the Atlantic 

 coast, and from the Red River Settlement and Canada to Georgia and West- 

 ern Missouri. It is said to be common in the mountains of the Carolinas, 

 and Audubon and Bach man state that "it is found in Tennessee and through- 

 out Louisiana". It is not, however, found in the "alluvial districts of Carolina 

 and Georgia", nor in Florida, and is presumably absent from all the low- 

 lands of the Gulf coast, and probably not to be met with "throughout Lou- 

 isiana", but oidy in the higher and more northerly portions. The authors 

 above cited state that in South Carolina it is not found nearer the seaboard 

 than Columbia. It is not enumerated by Roemeras an animal of Texas, nor 

 is it mentioned as occurring in the Southwest beyond Western Missouri. 

 Richardson gives it as common on the northern shores of Lakes Superior and 

 Huron, but states it as his belief that it does not range northward beyoncHhe 

 fiftieth parallel. Hall enumerates it among the animals of Canada, and Gil- 

 pin among those of Nova Scotia.* Adams gives it as very common in New 

 Brunswick, as it likewise is in Maine and throughout the Northern States.

"Mr. R. R. McLeod, of Houlton, Me., also writes ine that it is very numerous in Sholbouine, 

 Kind's, and Queen's Counties in Nova Scotia.
