It is likely that one or both of 

 these sites constitute the type 

 locality of the species. 



*♦. Locations not yet investigated believed 

 likely to support additional natural 

 populations: Areas between the two centers 

 of distribution may harbor a few scattered 

 localities. In addition, it is likely that 

 other occurrences are extant in the St. 

 Maries River and adjacent drainages in Idaho
