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 : 



Eophyton linnceanum, Torrell. 

 Cruziana similis, Billings. 

 Linc/ula Murrayi, Bill. 

 Hyolithes excellens, Bill. 

 Senella reticulata, Bill. 

 Stenotheca pauper, Bill. 

 Microdiscus Dawsoni, Hartt. 

 Paradoxides tenellus, Bill. 



The Upper Potsdam as represented in Canada and parts of 

 the United States does not appear in Newfoundland. 



Calciferous. The calciferous group which in Canada forms a 

 prominent feature, having a thickness of 300, feet and a large 

 fossil fauna, does not appear to be defined in Newfoundland, 

 although H 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 Quebec Group/' of which I shall now say 

 a few words : 



The Quebec Group. This 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, etc., 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.
