« Ten specimens. 



Specimens from different geographic areas average, respectively, as follows: 



I am not able to discern any difference in coloratioia between the several series, 

 except that those from Ungava are possibly a little darker than the others, while 

 several specimens from Fort Simpson and Fort Rae, Mackenzie, are a little paler and 

 browner. The latter (not included in the above measurements) are, however, very 

 old skins, and their paler and browner coloration may be due to fading.
