Type locality. Eastern Canada. 



Faunal distribution. Canadian, Lower Hudsonian and upper transition 

 zones; Atlantic Ocean to the Great Plains. 



Distribution in Pa. and N. _/.- Once abundant in all the mountainous and 

 well-forested areas of the Canadian and upper transition zones in Pa. Also 

 once found sparingly in parts of the mountains of northern N. J., but a long 

 while exterminated in that State. 



Records in Pa. The following have been sent in answer to inquiries as to 

 distribution and present status of this species : 



Armstrong Co. " I have heard reports of the occurrence of this species in 

 the Buffalo Creek region of Armstrong Co." Todd, 1902. 



Bradford Co. Reported by Stevens. 



Bucks Co. Subfossil remains found in Durham Cave in 1893 near Riegels- 

 ville, identified by Prof. E. D. Cope. Mercer.

 Buffalo Creek Region." Todd, 1902.

 1899." Todd. "An exceptionally fine one received from Mr. E. K. Morse, 

 killed near Penfield, Dec. 8, 1900." Todd. 



Clinton Co. Several specimens have been sent me from time to time by 

 Seth Nelson, who reports them numerous. In my own experience I found 

 this to be the case in the same region in 1898. They seemed to prefer the 

 tops of the mountains, but sometimes came down to the banks of the Sinne- 

 mahoning. Rhoads. Plenty around Mill Hall in 1879. Pfoutz. 



Columbia Co. " A stray one seen now and then ; plenty on North
