afforded fossil plants is Perry, near Eastport, in the eastern part 
and trappean or tufaceous rocks, which, according to the recent 
servations of Prof. C. H. Hitchcock, ® rest unconformably on

Series observed at St. John n, New Brunswick ; and it is probable 
that th Bone, ey are re, Upper Devonian. The following species occur at
