156 NOTES ON THE GEOLOGY OF NEWFOUNDLAND—WESTON. 
CRUSTACEA,— 
Bathyurus timon, Billings. 
Asaphus morosi, Billings. 
Lllenus arcuatus, Billings. 
Agnostus fabvus, Billings. 
For other fossils of the Quebee group from Newfoundland, 
see Billings’ Paleeozoie 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. I 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 Gaspé sandstones of Canada, 
which at Gaspé, according to one of Logan’s sections, has a thick- 
ness of 7,036 feet, consisting of sandstones, shales, limestoues, 
conglomerates, ete. It is not well defined but some of the fossils 
which characterize the Gaspé sandstones at Gaspé have been 
found also in Newfoundland, among which are Psilophyton, 
Lepidodendron, Sigillaria, Sphenopteris. The Gaspé 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. Inst. of Se., Vol. III, page 357.)
