"158 Geology and Fossil Flora of P.E.I. 



The object of these remarks is, however, more especially to 

 consider the testimony of the fossils recently collected by Mr. Eain 

 •when added to that previously obtained. On this I would 

 remark : — 



1. That the beds at Miminigash, Gallas Point, St. Peter's 

 Island, Governor's Island, Rice Point and other places on the 

 south coast, contain plants which elsewhere characterize the 

 Upper Carboniferous and Lower Permian. 



2. At certain points in the interior of the Island and in the 

 l>ays of the north coast, which represent troughs between the 

 Permo-carboniferous anticlinals, there are found plants indicat- 

 ing a higher horizon. Here the characteristic Carboniferous species 

 are absent, and their place is taken by others, either Permian or 

 Triassic. For example, the abundant coniferous wood of the 

 Carboniferous species, Dadoxlyon materiarium, is replaced by an 

 entirely different type more characteristic elsewhere of the 

 Trias, Dadoxylon edvardianum. Some of the fossils found in 

 this by Mr. Bain are undoubtedly of Permian aspect, as, for 

 instance, the Walchias and Calamites gigas. Others, like the 

 Dadoxylon above referred to and the curious Cycadoidea dbeqid- 

 ensis are undoubtedly more Triassic in aspect. 



3. In the beds on the north side of the Island in which 

 we found no well-characterised plants, but which afforded the 

 remains of the Dinosaur, Bathygnathus borealis, Mr. Bain finds 

 a few plants which he considers distinct from those in the lower 

 beds. These must, I think, from their associations, be regarded as 

 Triassic, though too few and imperfect to afford satisfactory terms 

 of comparison with that formation elsewhere. 



1. Permo-carboniferous. 



The species catalogued from this formation in my Beport of 

 1871, and my paper of 1874 in the Journal of the Geological 

 Society of London, were the following: — 

 Dadoxylon materiarium, Dn. 

 Walchia gracilis, Dn. 

 l( robusta, Do. 

 Calamites suckovii, Brongt. 

 " cistii, Dn. 

 " gigas, Dn. 

 Neuropteris rarmervis, Bunbury.
