 seen during our stay. 



SCIUROPTERUS SABRINUS MACROTIS, new subspecies. 



CANADIAN FLYING SQUIRREL. 



During* recent years, Sciuropterus sabrinus (Shaw) has been considered 

 a subsi)icies of tSciuropteruH volans (Lin- 

 nanis); but jAIr. Outrani Bangsh as lately 

 shown' these two to be distinct species. 

 Moreover, tlic form of SciuropterKs sabrinus 

 occupying the Canadian life zone, along 

 the northern border of the United States 

 east of the Great Lakes, is so markedly 

 different in size, coloration, and propor- 

 tions from typical sabrinus,^ that it requires 

 separation as a subspecies.

^RespectinjL'- the type locality of his ' Sciurns sahrinm,' Shaw, iii his General 

 Zoolojiy, IWl, II, Ft. 1, p. 157, states as follows : " It is found in the southern parts of 

 Htidnon's Bay, in the forests borderinj'- on Serern river in James's Bay, and 8(}ems to 

 hiive been lirst describtnl by Dr. Forster in the Philosophical Tran8a(^tion8. I have 

 j;iven this species a new trivial, in order to avoid the repetition of the title ITiid- 

 sonhis, whieh takes place, through oversight, in the Gmelinian edition of Systenia 

 Naturii'."
