' All the licliens here enumerated, excepting- the species Pilophoron, are of wide northern 

 distribution, which the localities here indicated exhibit nothings of. Many other boreal 

 species will reward search, and from some indications seen, we may expect the lichens of 

 the southern part of Russian America to show some special affinities to the interesting lichen 

 llora of California. H. M.
