The present Report, which forms the second part of the third volume 

 of " Palaeozoic Fossils " now in course of publication by this Survey, 

 consists of two papers, viz.: (2) a revision of the fauna of the Guelph 

 formation of Ontario, with descriptions of a few species, and (3) a 

 systematic list, with references, of the fossils of the Hudson River or 

 Cincinnati formation at Stony Mountain, Manitoba. 



The drawings for the seven plates illustrative of the first of these 

 papers, were made from nature by Mr. L. M. Lambe, F.G.S., the artist 

 to the Survey, and reproduced on stone by Mr. O. E. Prud'homme.
