Nylander records the occurrence of the species at St. Lawrence 
Island and Port Clarence. In his synopsis he does not recognize either 
variety, both being given as synonyms of the species itself. It is 
probable that both varieties were represented. As I have followed 
Tuckerman in separating the varieties, this makes the first Alaskan 
record of the distinct varieties.
