CANADIAN FOSSILS. 



havo been published in two papers in the Proceedings of the Ooological 

 Society of London,* and in so far as thoy relate to New Brunswick, in 

 the second edition of my " Acadian Ocology," 1868. 



In the preparation of the latter work I had the advantage of examining 

 a large collection from the prolific beds of Carlton, near St. John, New 

 Brunswick, made a few years ago by Mr. (now Professor) Ilartt, under 

 the auspices of the Natural History Society of New Brunswick, and which 

 may be regarded as almost exhaustive of that locality. A detailed 

 section prepared by Prof. Hartt, and illustrating the distribution of the 

 plants in the several beds, is also included in the notice of the locality in 

 Acadian Geology. 



Since the publication of the last- mentioned work, the explorations of the 

 Geological Survey in the southern part of New Brunswick have traced 

 the Devonian plant-beds to the westward of St. John, and have brought 

 them into stratigraphical juxta-position with the Upper Silurian and Lower 

 Carboniferous rocks «f that region, thus farther confirming their geologi- 

 cal age. Several new species, and specimens illustrative of forms previously 

 known, have also been discovered, more especially at Lopreau and its 

 vicinity. The researches of the officers of the Survey have also rendered 

 it probable that the beds at Perry in Maine, which have affordod so many 

 interesting fossils, may belong to a Devonian horizon somewhat higher 

 than that of the St. John plant-beds, and that this may possibly servo to 

 account for their comparatively unaltered condition. | 



The largo amount of material and of new facts to which I have thus 

 had access, together with important discoveries made by Prof. Hall and 

 Dr. Newberry in the Devonian of the United States, appeared to render 

 possible a general revision of the whole Devonian Flora of Eastern 

 America ; but, before attempting this, I was desirous to have the oppor- 

 tunity of revisiting and more fully exploring the clifis of Gasp^ Bay, with 

 the view more particularly of studying the type of plant which had proved 

 to be, of all others, most characteristic of the Devonian Flora, viz., the 

 genus Fsilophyton, and which occurs more abundantly, and in better pre- 

 servation, there than at any other known locality. This design I carried 

 out in the summer of 1869, under favorable circumstances as to weather, and 

 ■with the valuable aid of Mr. G. T. Kennedy, B.A., and Mr. G. M. 

 Dawson, both good collectors. The more fully to do justice to the work 



• " On the Flora of the Devonian Period in North-Eastern America, "— 18G2. Further 

 Observations on the Devonian Plants of Maine, Ga3p6, and New York "—1863. 



t The Perry beds rest uncomforraably on a series of supposed Upper Silurian 

 beds, which, traced eastwardly, probably underlie the Devonian plant-beds of 

 Lepreau. The Flora of the Perry beds is precisely equivalent to that of the Upper Devo- 

 uian of Peuusylvaaia and New York, and quite distinct from that of the Lower Carboniferons.
