Variations in both coloration and dimensions, according to locality, indicate the 

 possibility that further subdivision of the species may be required. Specimens 

 from St. Michael and one from St. Lawrence Island have very dark upper parts, the 

 dorsal region being mostly black, with very little of rusty. Examples from Bering 

 Island, Commander group, represent the opposite extreme, rusty predominating on 

 the upper pans, except one specimen, which is almost precisely like one from 

 Muller Bay, Alaska Peninsula.
