The following Report contains descriptions, for the most part accompanied by figures, 
of the fossils which I collected during the year 1873, in the Devonian rocks of Western 
Canada, by the help of a grant set apart for this purpose by the Government of Ontario. In 
some few cases, for the sake of completeness, Ihave also included descriptions of remains 
which I have collected upon other occasions from the same deposits, but which did not come 
under my notice during the investigation of which this is a special record. 
The collections herein described were mainly made from the inferior portion of the 
Devonian series (Oriskany Sandstone and Corniferous Limestone) ; but the Hamilton group 
was likewise, though less carefully, examined. 
The time and means at my disposal being both limited, I thought it advisable rather to 
make a careful and prolonged examination of the fauna of a limited district, than to make less. 
exhaustive collections from a wider area and from scattered localities. In accordance with 
this view, I repeatedly and very carefully examined the various fossiliferous localities in the 
Devonian rocks of the Townships of Wainfleet, Humberstone, and Bertie, in the County of 
Welland, on the north shore of Lake Hrie. JI also visited, more hurriedly, the same deposits 
further to the west, as they occur in the Townships of Oneida and Walpole, in the County of 
Haldimand. 
In investigating the remains of the Corniferous and Hamilton formations, it is hardly 
necessary for me to remark that I have been very greatly indebted to the various memoirs and 
works upon this subject by Mr. Billings and Prof. James Hall. The wood engravings, with 
two exceptions, and all the figures in the lithographic plates which accompany this work, are 
original.
