FLORA OF THE CARBONIFEROUS PERIOD. 431 



the traces named Sauropus primmvus by the latter author. For 

 thi3 reason, until we shall obtain some knowledge of the animal 

 from more. definite remains, I propose for it the name of Sauropus 

 Sydnensis. The specimen was discovered by Mr. Brown, and 

 is now in his collection. 



These footprints add a ninth species to the reptilian fauna of 

 the Coal Formation of Nova Scotia, and are the first traces of this 

 kind discovered in the Cape Breton Coal-field.

Art. XXX. — Synopsis of the Flora of the Carboniferous Period 

 in Nova Scotia; by J. W. Dawson, LL.D., F.R.S., F.G.S., 

 &c, Principal of McGill College. 



The following list includes the plants in the collection of the 

 writer, and in collections submitted to him by several geologi- 

 cal friends ; as well as those previously catalogued by Mr. Bun- 

 bury, in Sir Charles Lyell's Travels, and in the Journal of the 

 Geological Society, and by Mr. R. Brown and the author, in the 

 list appended to " Acadian Geology." 



The present synopsis was not prepared so much for immediate 

 publication, as in aid of the writer's investigations of the charac- 

 teristic plants in the numerous coal beds at the South Joggins, 

 and of the conditions of formation of those beds ; but as some 

 time may elapse before the publication of these researches, and 

 the want of a list of the known species is much felt by those 

 engaged in the study of the carboniferous rocks, it has been 

 thought advisable to print it in the present form. 



The new species are accompanied by short characters ; but 

 many of the details which might have been given are omitted for 

 the sake of brevity. The collectors of the specimens examined 

 are mentioned in every case, when known to the author. The 

 part of the carboniferous system in which the species occur 

 has also been stated ; and as some confusion has lately arisen 

 from the use of the term " sub-carboniferous," by authors, it is 

 proper to state that the name " Lower coal formation " in this 

 paper is equivalent to " sub-carboniferous " of Dana ; that " Middle 

 coal formation " denotes that part of the system over the Marine 

 Limestones and holding the principal coal beds ; and that " Upper 

 coal formation " is applied to the newer part of the system over 

 the productive coal measures.* These three members are, to a
