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.
