S. Barrattiana seems not to occur in the United States, but there Is the 

 following variety which represents the type in Montana and Wyoming, 

 Ball regarded it as a good species and In Ilcrh. W, he also referred to it a 

 specimen from British Columbia, Emerald Lake, Avalanche Path, collected 

 on June 20, 1904, by R. T. Shaw (No. 1, m., f.; named S. conjiincta by 

 jNIacoun). If tliis specimen really belongs to this variety it would connect 

 its range with that of the type. The synonymy of the variety is as foUow^s:

' Bobb gave the descriplion In May 1S94 in a letter. But "the varietal name [denudaia] 

 used by Mr. Bebb being preoccupied has been changed to the one given above." Rose in note.
