Westphalian is the character of the Fern Ledges flora. 

 "The genus Megalopteris alone, is entirely unrepresented 

 in the Westphalian of Europe, but it is a peculiar form 

 which is confined (though recently Arker identified a 

 small fragment from the British Coal Measures as belonging 

 to this genus) to North America, where it has been recognized 

 in beds of undoubtedly Pottsville age. Otherwise the 

 leading species have not merely allies in the Westphalian 

 flora of Europe, but are identical in the majority of cases. 

 We may take it as indisputable that the Fern Ledges 

 flora is of Westphalian age and that probably it corresponds 

 in point of time most nearly to the lowest zone of the middle 

 Westphalian. The specific identity between so many 

 of the plants from Europe and Canada is a point of great 

 interest in relation to the geographical distribution of the 

 forms. 



BIBLIOGRAPHY. 



The general geology of the area in the vicinity of St. 

 John city, and the faunas of the Cambrian and the flora 

 of the Little River group have been exhaustively dealt 

 with by Dr. G. F. Matthew in a long series of articles 

 appearing in the Proceedings and Transactions of the 

 Royal Society of Canada from volume I (1882-83) onwards.
