154 NOTES ON THE GEOLOGY OF NEWFOUNDLAND—WESTON. 
which are now placed in the next zone—Middle Cambrian. I 
mention here only a few of the most typical forms: 
Hophyton inneanum, Torrell. 
Cruziana similis, Billings. 
Lingula Murrayi, Bill. 
Hyolithes excellens, Bill. 
Senella reticulata, Bill. 
Stenotheca pauper, Bill. 
Microdiscus Dawsoni, Hartt. 
Paradoaides tenellus, Bill. 
The Upper Potsdam as represented in Canada and parts of 
the United States does not appear in Newfounaland. 
Caleiferous.—The calciferous group which in Canada forms a 
prominent feature, having a thickness of 300 feet and a large 
fossi] fauna, does not appear to be defined in Newfoundland, 
although it is said to be represented there by a thickness of 
1,000 feet, and another set of strata over 200 feet thick which 
may belong to the upper calciferous zone. 
This great thickness of rock does not appear to have yielded 
any typical calciferous fossils. From my personal observations 
I am inclined to think that a great portion of it belongs to the 
series known as “ The Quebee Group,” of which I shall now say 
a few words: 
The Quebec Group.—tThis great metalliferous group which 
forms an important feature in our Canadian geology is largely 
developed in Newfoundland and is characterized by the same 
varieties of rock, among which are various coloured limestones, 
black, gray, green, red, and other shales and slates, conglomer- 
ates, serpentines, etc., forming a thickness of over 5,000 feet. 
It is in Newfoundland, as in Canada, the great mineral-bearing 
belt of rocks, in which silver, copper, lead, iron, manganese, 
plumbago, gypsum, marble, petroleum, ete., have been found. 
It was recognized by the finding of typical Levis fossils 
—Graptolites—which are peculiar to this zone of the Quebec 
group of Canada.
