The lower portion of "Division C" perhaps ought not to 

 be included in this part of the section, and may eventually 

 prove to be equivalent to the ^wce//«-bearing beds of 

 Tatlahcoh Lake, and to represent also a horizon consider- 

 ably below the upper portion of C . Farther south, upon 

 the northern end of Vancouver Island, in the vicinity of 

 Quatsino Sound, the three upper members of this series 

 are found. Here also Aucella and other species are 

 reported which appear to belong to the Knoxville. 



At the southern end of Vancouver's Island, near Comox 

 and Nanaimo, strata occur that have been correlated with 

 the Chico of California ; they consist of shales and conglom- 

 erates, amounting in thickness to about five thousand feet. 

 These deposits contain the coal-bearing beds of Vancouver's 

 and the neighboring islands. Still further southward, on 

 the borders of Puget Sound, is the coal-bearing Puget 

 Group of White (1889), which has been compared to the 

 Laramie, a series that is thought to be of Tertiary age, or 

 at least later than the Chico. 



The relative position of these deposits, all of which rest 

 directly upon earlier Mesozoic or older rocks, suggests a 

 Cretaceous basin extending southward, in which there was 

 a continued subsidence and transgression of the sea similar
