2o8 The Ottawa Naturalist. [January 



W. D. Matthew^ call for a few comments as reg^ards the geo- 

 logical position of tlie Belly River series or formation. 



In defining the series, Dr. G. M. Dawson,- and R. McConnell 

 write : " Briefly stated, it would appear from investigations now 

 reported on that considerable area of the beds, which in 1874 I 

 called ' Lignite Tertiary,' here and in previous announcements 

 designated as Belly River series must be relegated to a position 

 below the Pierre shales," and further adds: "The beds thus 

 separated as the Belly River series were, in 1875, by me correlated 

 with the Judith River series of the Missouri." 



Later, in i886, R. G. McConnell^ gave the succession of the 

 "Cretaceous formation ' inhis "Report on the Cypress Hills, Wood 

 Mountain and adjacent country," in descending order as follows : 



(Laramie. 

 Fox Hill. 

 Pierre. 

 ^ Belly River series. 

 and in p. 65C, he unites the Pierre and Fox Hill deposits together 

 under the same head, and lists the marine invertebrate fauna 

 determined by Dr. Whiteaves (pp. 66C & 67C.). 



In 1887, J. B. Tyrrell* gives the following succession in 

 descending order : 

 Laramie 



Paskapoo series. 

 Edmonton series. 

 Fox Hill and Pierre. 

 Belly River series. 

 Of these, Tyrrell placed the "Paskapoo" beds in the Eocene 

 Tertiary and the remainder below (as cited) in the Cretaceous. 



In his "Cretaceous System in Canada," Dr. Whiteaves gives 

 the following succession o( the Cretaceous of Manitoba and the 

 North West Territories :
