Baird says, "No locality was assigned, but the animal is undoubtedly 

 North American, probably from the New England States or New York ; 

 possibly from Iowa or Minnesota." According to A. B. Howell (North 

 Amer. Fauna 50: 13, June 30 [=Aug. 5], 1927, the type locality "may well 

 be considered as situated somewhere in the northern or western portion of 

 the New England States, or in western New York." The skin is little 

 more than a ball of fur. Head, legs (except one foreleg detached), and 

 tail are lacking. Skull Grade C.
