2. Maine. — The only locality in this State that has hitherto 

 afforded fossil plants is Perry, near Eastport, in the eastern part of 

 the State. The plant-bearing rocks are grey sandstones, resembling 

 those of Gaspe, and associated with red conglomerate and trappean 

 or tufaceous rocks, which, according to the recent observations of 

 Prof. C. H. Hitchcock*, rest unconformably on shales or slates hold- 

 ing Upper Silurian fossils t. I have little doubt that these beds at 

 Perry are a continuation of part of the series observed at St. John, 

 New Brunswick ; and it is probable that they are Upper Devonian. 

 The following species occur at this place : — 



Lepidodendron Gaspianum, Dawson. 

 Lepidostrobus Eichardsonii, Dawson. 



globosus, Dawson. 



Psilophyton princeps, Dawson. 

 Leptophloeum rhombicum, sp. nov. 



Megaphyton ? 

 Aporoxylon ? 

 Cyclopteris Jacksoni, Dawson. 



Brownii, sp. nov. 



Sphenopteris Hitchcockiana, sp. nov. 



3. Canada. — Devonian beds holding fossil plants occur in Eastern 

 Canada, in Gaspe, and in "Western Canada, at Kettle Point, Lake 

 Huron. At the former place there is an extensive series of sand- 

 stones and shales, regarded by Sir "W. E. Logan as representing the 

 whole of the Devonian series, and containing plants throughout, but
