II. On the Fossils of the Cretaceous Bocks of Vancouver and Adjacent Islands 

 in the Strait of Georgia. 



Prefatory Kemarks. 



The fossils described in the following pages were collected by Mr. 

 James Richardson from the south-eastern portion of Vancouver Island 

 and from several islands in the Strait of Geoi-gia, during the summer 

 seasons of 1871 to 1875, inclusive. In order, however, to p.-esent as 

 complete a report as possible on the present state of our knowledge of 

 the fossil fauna of these deposits, the names of species described or 

 recorded from them by other naturalists, but which were not met with 

 by Mr. Richardson, have been added in their proper places between 

 parentheses. 



According to Mr. Richardson's published reports,* the coal-bearing 

 strata of this part of Vancouver Island occupy a long, narrow strip on 

 the shores of the Greorgian Strait, but in the neighbourhood of Nanoose 

 Harbour the continuity of the f)rmation is broken by crystalline rocks, 

 which divide it into two locil an I subordinate areas, one of which has 

 been called the Comox, and the other the Nanaimo Coal-Field. The two 

 together are believed to form part of a synclinal axis, whose north-east 

 side lies beneath the waters of the Strait of Georgia, and the limits of 

 each are shewn in detail in the maps which accompany Mr. Richardson's 

 I'sports. 



The Comox Coal-field extends from the north-west of North "West Bay 

 to Cape Mudge, and includes Denm an and Hornby Islands, The following
