 see Billings' Palseozoic fossils. 



In this short description it would take too much space to 

 record information obtained of other members of the upper and 

 lower silurian. Some of these are not represented as in Canada, 

 while others probably never will be well defined owing to the 

 absence of, or a poor state of preservation of the fossils, which 

 consist chiefly of corals, stems of encrinites, and other forms 

 which are not typical of any formation between the Trenton and 

 Devonian. 1 shall therefore conclude with a few remarks on 

 the Devonian, Carboniferous and Superficial formations. 



The Devonian. This formation in Newfoundland is supposed 

 to be equivalent to a portion of the Gaspe sandstones of Canada, 

 which at Gaspe, according to one of Logan's sections, has a thick- 

 ness of 7,036 feet, consisting of sandstones, shales, limestones, 

 conglomerates, etc. It is not well defined but some of the fossils 

 which characterize the Gaspe sandstones at Gaspe 1 have been 

 found also in Newfoundland, among which are Psilophyton, 

 Lepidodendron, Sigillaria, Sphenopteris. The Gaspe series 

 contains a large fossil fauna and is important owing to its 

 petroleum springs and other minerals. 



Carboniferous formation. Murray states that the carbonifer- 

 ous of Newfoundland is clearly an extension of the rocks which 

 constitute the coal-fields of Cape Breton and Nova Scotia. The 

 formation consists of conglomerates, shales, limestones, sand- 

 stones and interbedded coal seams. Jukes, in his geology of 

 Newfoundland, speaks of a seam of coal 6 inches thick on the 

 Coal Brook. Other thicker workable seams have of late years 

 been reported. A description of the coal mining district by Dr. 

 Gilpin is to be found in the transactions of this Society (Trans. 

 N. S. List, of Sc., Vol. Ill, page 357.)
