The Utica terrane occupies a more or less narrow and 
continuous belt along the north shore of the St. Lawrence 
from Cape Tourmente below Quebec, .to Montreal, whence 
the belt trends to the south and is seen in the neighbour- 
hood of Lacolle, Clarenceville, etc.—then crossing the 
boundary line—rounding the edge of or skirting the Adiron. 
dack range—to reappear north of Lake Ontario at and in the 
vicinity of Whitby—it crosses the Province to Colling- 
wood where it again disappears beneath the waters of the 
Georgian Bay and continuing north and west strikes 
numerous points, capes and islands about the great Mani- 
toulin Island dying out to the west and overlaid by newer 
and overlying formations. 
In the vicinity of Quebec the Utica terrane is met at 
several localities. Characteristic species were collected by 
Rev. Prof. Laflamme, Mr. St. Cyr, Mr. T. C. Weston, Dr. 
Ells and the writer within recent years, at Montmorenci, 
Beauport, St. Charles River Flats, Charlesbourg, half-mile 
west of Charlesbourg, at Grondines, Pointe aux Trembles 
and Cape Santé, and also across the river at St. Antoine 
[de Tilly] interesting collections were made. 
At Montmorenci Falls, near the bottom of the falls and 
ravine the following characteristic Utica fossils were col- 
lected and detected by the writer and Dr. Ells :— 
. Orthograptus quadrimucronatus, Hall. 
. Diplograptus sp. 
. Climacograptus sp. 
Reteograptus ? Eucharis, Hall.
