fairly typical and have been used for comparison in most instances. It 

 is quite possible, however, that a series of skins from Hudson Bay 

 would measure slightly more than the Minnesota specimens, and would 

 perhaps differ in color. While this material, taken in connection with 

 what is available from the type locality is sufficient for comparison with 

 the subspecies here recognized, it will not permit the recognition of 

 other nominal forms which may eventually prove to be well founded. 

 A skull from Saint Catharines, Ontario, however, which may be con- 

 sidered a topotype of canadensis, is identical in appearance with one 

 from James Bay.
