PREFACE. 



The following Report contains descriptions, for the most part accompanied by fL- 

 of the fossils which I collected during the year 1873, in the Devonian rock.- t \\Ystern 

 Canada, by the help of a grant set apart for this purpose l>y tin- < .overnment of Ontario. In 

 some few cases, for the sake of completeness, I have 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 tin. 

 Devonian series M)ri,-kany 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 rath, r t 

 make a careful and prolonged examination of the fauna of a limited district, than to make K--- 

 exhaustive collections from a wider area and from scattered local itie.-. In accordant- with 

 this view, I repeatedly and very carefully examined the varinu- fo-siliferoiis localities in the 

 Devonian rocks of tin- T'>wn-hip- of Wainfleet, Bumberstone, and Bertie, in the I'ountv ol
