7. On some additional or imperfectly understood fossils from the Hamilton 

 formation of Ontario, with a revised list of the sjxcies therefrom. 



The second paper in this volume, on the fossils of the Hamilton forma- 

 tion of Ontario, was based upon all the specimens that the writer had 

 seen, and upon all the information on the subject that was available up 

 to the close of 1886. In that paper, the names of the earliest collectors 

 of the fossils of these rocks and the dates at which the collections 

 were made, were inadvertently omitted. All the authentic information 

 on these points that the writer has been able to gather, is as follows : — 

 1855. Alexander Murray and James Hall collected fossils together at 

 Widder and along the Riviere aux Sables at Bartlett's Mills, and 

 elsewhere, in 1855, as stated in Murray's Report for that year and 

 verbally by Professor Hall to the writer in the spring of 1890. 

 1868. Numerous fossils in the Museum of the Survey are labelled 



"Hamilton formation, Bosanquet, J. Pettit, 1868." 

 1873-74. Professor H. A. Nicholson (in a letter dated March 7, 1898) 

 says that his collecting near Widder and Arkona was carried on 

 principally, if not entirely, during the years 1873 and 1874. 

 1872-79. Dr. G. J. Hinde (in a letter dated February 5, 1898) says 

 that he collected fossils at Thedford (Widder) and the neighbour- 

 hood for the seven consecutive years from 1872 to 1879, both 

 years inclusive. 

 (Since this paper was written, the publication of several monographs on 

 special groups of fossils has thrown new light upon this local fossil fauna, 

 and much additional material has been accumulated by local collectors. 

 During three visits to Thedford, in 1889, 1891 and 1897, the writer has 

 not only collected the fossils of that neighbourhood (inclusive of Bartlett's 

 Mills) but also made careful examinations of the collections made by the 

 Rev. Hector Currie, and more recently by Mr. G. Kernahan and Mr. N. 

 J. Kearney, of Thedford. These gentlemen have kindly lent to the writer 

 most of the choicest specimens that they have obtained up to the present
