ADDITIONAL NOTES ON THE CAMBRIAN OF CAPE BRETON 379 
brian, the volcanics are thought to belong to the latter, and to give the 
natural base of this system. 
The accompanying table will then show the classification of the 
Cambrian System, as seen in the Maritime Provinces of Canada. 
See accompanying sheet. ) 
In this table we have been able to present one of the faunas 
of the European Cambrian, heretofore unrecognized in Eastern 
Canada, i. e., the Tremadoc fauna of English writers, the Ceratopyge 
fauna of the Swedes (the Euloma-Niobe fauna of Prof. W. C. Brogger), 
the Dicellocephalus fauna of Mississippi valley. 
This is based on the discovery of examples of Asaphellus, Para- 
bolinella and Triarthrus in soft shale on the upper part of McLeod 
Brook, in Boisdale district. It happens that at St. John the strata 
which would carry this fauna is in the channel of the river in the upper 
part of the harbor of St. John, with the Dictyonema fauna on one 
shore, and the Tetragraptus fauna on the other, hence it has not been 
recognized in the St. John Basin. 
Also, the strata of Division 2 of the St. John group, the 
Johannian division, which we have all along spoken of as the probable 
place of the Olenus, it would seem will have to be assigned largely to 
the Paradoxides Zone, since Mr. Loper, who has been collecting in 
Cape Breton for the U. S. Geological Survey, has found a Para- 
doxides, which proves to be a variety of P. Forchhammeri, in the 
middle of this Division. From this it may be inferred that the two 
lower bands {a and h) of this division may be assigned to the Para- 
doxides zone. I had found in the Mira R. Cambrian a cheek of 
Paradoxides type in this division, but this alone was not sufficient 
to determine the presence of this genus in the Johannian division. 
Another important point made during the past season was, that 
the strata at Young’s Point (or McFee’s Point), from which the fossils 
came, collected by Messrs. Weston and Robert many years ago for the 
Canadian Geological Survey, and which the author had described, and 
referred (on account of their resemblance to European forms) to the 
Ordovician fauna, are in the Etcheminian or basal Cambrian. The 
more abundant material gathered since Messrs. Weston and Robert’s 
visit, show that the species referred by me to Orthisina is a Billing- 
sella. The Holasaphus does not agree with any other basal Cam-
