I am not able to disi-ern any difference in coloration between the several series, 

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

 several sjiecimens from Fort Simpson and Fort Rae, ^lackenzie, are a little paler and 

 browner. Tlie latter (not included in tlie above mea.surements) are, however, very 

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