A NEW FLYING SQUIRREL FROM THE COAST OF 

 ALASKA. 



BY WILFRED H. OSGOOD. 



Nearly all the resident birds and mammals of the coast region 

 of southeastern Alaska belong to peculiar forms characterized by 

 dark intensified colors. Among the few mammals that have 

 thus far escaped description is the flying squirrel. It has been 

 long known to occur there but, until recently, specimens have 

 not reached any of our museums. 



Some two years ago, while working in the region, I commis 

 sioned a trapper to secure specimens of flying squirrels for the 

 Biological Survey and gave him instructions in preparing skins. 

 As a result, a series of six well -prepared specimens have been 

 recently received. These, as was expected, are quite different 

 from any of the previously described forms. For the privilege 

 of describing the new form I am indebted to Dr. C. Hart 

 Merriam .
