and Norman’s Kill fauna, which answers to the fauna of the middle zones of the European 
Ordovician or Cambro-Silurian rocks. 
(8.)—In each of these grand faunas are found two subfaunas, those of the lower 
faunas being the more distinctly separable :— 
A.—QUEBEC OR CALCIFEROUS-CHAZY FAUNA. 
Subfauna 1.—Cape Rosier and Barrasois River Zone, of Calciferous age—Tre- 
madoc Rocks of Great Britain and Ceratopyge and Dictyonema Beds of Norway. 
Subfauna 2.— Ste. Anne River Zone, of Point Levis age=typical Arenig of Great 
Britain ; Phyllograptus Beds of Scandinavia, etc. 
B.—TRENTONIAN, MARSOUIN RIVER, oR NoRMAN’s KILL FAUNA. 
Subfauna A.—The Coenograptus Zone of Griffin Cove and the Marsouin River 
answering to the Middle Llandeilo Beds of Great Britain, to the Glenkiln Beds of 
Scotland, ete. 
Subfauna B.—The Cove Fields and Orleans subfauna; apparently destitute of 
Cenograplus gracilis, and answering to the highest Llandeilo or Lowest Caradoc 
Beds of England. 
(4)—The last of these subfaunas shews evidence of a transition into the Utica- 
Lorraine Graptolitic fauna of the Mohawk valley, New York, and of Lake St. John, 
Canada. 
(5.)—From a comparison of the foregoing facts, it follows that :— 
First.—If the strata associated with the Pillar Sandstones near Cape Chatte and else- 
where actually contain Phyllograptus (see Report Geological Survey Canada 1880-1-2, 
p. 26 pp.) then, as these strata always appear to come between the Levis conglomerates and 
the Marsouin rocks, there may be no necessity for presuming any general fault or overlap 
between the so-called Levis beds of the Gaspé-Marsouin area and the more recent so-called 
Utica beds of the same district. There may be, on the other hand, in some localities an 
uninterrupted succession from the base of the Cape Rosier rocks into the very highest 
beds along the south shore of the St. Lawrence. 
Secondly—If there be no break in the great succession, then the sequence in the 
Gaspé peninsula must be simply regarded as generally inverted, faults and folds being 
probably present in abundance; but the succession from the St. Lawrence southward 
must be regarded as a generally descending one. On this supposition, if we may judge 
from the local sequence of the rocks and fossils as laid down in Mr. Ells’s “ Report on the 
Geology of the Gaspé Peninsula” (Report of Progress 1880-1-2, Dp viii.) the ascending 
succession may perhaps be somewhat as follows :— 
Possible Ascending Succession of Strata, on the South Side of the St. Lawrence, from Cape Gaspé 
to Tartigo River.
