and its theoretical significance will be referred to in tlie conclud- 

 ing part of this memoir. 



In the above local details, I have given merely the facts of 

 greatest importance, and may refer for many subordinate points 

 to the papers catalogued in the introduction to this memoir, and 

 to the reports of the Geological Survey of Canada. 



PART III. — REVISION OF POST-PLIOCENE FOSSILS OF CANADA, 



The list of Post-pliocene fossils published previously to 1856, 

 amounted to only about 26 species. In my papers published 

 between that year and 1863, the number was raised to nearly 80. 

 My lists were tabulated, along with some additional species fur- 

 nished in MS, in the Report of the Geological Survey for 1863, 

 the list there given amounting to 83 species, exclusive of Fora- 

 minifera. In my paper on the Post-pliocene of Riviere-du-Loup 

 and Tadoussac, published in 1865, I added 38 species, and shall 

 be able still farther to increase the number in the present revision, 

 which will afi"ord a very complete view of the subject up to the 

 present time ; and though additional species will no doubt be 

 found, yet all the. principal deposits have been so carefully ex- 

 plored that only very rare species can have escaped observation. 

 For some of the additional species included in the present list, I 

 am indebted to Mr. G. T. Kennedy of Montreal, Dr. Anderson 

 of Quebec, and other friends, to whom reference will be made in 

 connection with the several species in the catalogue. 



SUB-KINGDOM RADIATA.

(1) Foraminifcra, 



Nodosarla {Glandallna) Jcevigata. 



(Var. Dentalina communis) 



Fossil — Leda clay, Montreal. 



Recent— Gulf St. Lawrence, 30 to 300 fathoms, G.M.D.^'^' 



This species is very rare in the Post-pliocene, but sometimes 



of large size and of different varietal forms. 



* The initials G. M, D., refer to the List of Foraminifera by Mr. 

 G. M. Dawsou in The Canadian Naturalist, 1870.
