Appended to this is a classified table of the genera and 
species characterizing the Utica of Canada, giving also a 
series of localities in the United States, typical localities as 
Utica, Eolland Patent, &c., for comparison.' 
From the same and the foregoing it will clearly be seen 
and naturally deduced that the so-called Utica or Hudson 
River shales of Quebec city, Cape Diamond, of the Marsouin 
River beds, of Norman’s kiln and ‘“Coenograptus ” shales 
in general do not occur anywhere in Canada where the 
Utica shales are found in their natural and undisturbed 
position between the Trenton and Hudson River terranes. 
These belong to a district and separate terrane—the 
Quebec terrane of the writer—and are characterized by a 
fauna whose affinities are more closely related to Lower 
Ordovician (Levis) faunas than to an upper member of the 
Ordovician system.
