On the “west side St. Joseph’s Island,” Lake Huron, a 
number of specimens thus labelled, probably collected by 
Mr. Murray also, indicated the presence of Leptobolus 
insignis, Hall, and Orthis testudinaria, Dalman, the latter 
being unusually large, and resembling a form which 
approaches O. emacerata, Hall. 
The above localities and lists of fossils from various por- 
tions of Quebec and Ontario present the leading character- 
istics of the Utica as it is seen to crop out along the con- 
tour or edge of the archean continent—in contact with it 
at times, and then overlapping the older members of the 
Ordovician system; at’ other times occurring as a more or 
less narrow belt of black bituminous strata lying interme- 
diate between the Trenton and the Hudson River, but 
throughout an almost uninterrupted belt of continuous 
. strata from Anticosti to the Manitoulin Islands. As can 
readily be seen the notes and remarks above made are from 
a paleontological staadpoint, and show the distribution and 
continuity of existing forms of life during Utica times as 
the shales were being deposited in the old Ordovician sea. 
Besides the above localities occurring along this con- 
tinuous belt or zone of Utica, there are two well-known 
paleeozoic basins, that of Lake St. John and Ottawa in which 
this terrane is well developed and in which there are 
numerous and varied forms of animal life entombed. This 
points clearly to the fact that in Utica times and in these 
two isolated and quite separate basins, similar conditions of 
deposition, sedimentation and conditions under which life 
existed were present in those early days similar to the con- 
ditions outside of these basins.
