queen charlotte islands 



In 1873 James Eichardson ^ discovered and described fossiliferons 

 Lower Cretaceous on the Queen Charlotte Islands. A more elaborate ac- 

 count of -the geology was published in 1880 by Geo. M. Dawson." The 

 flora has been studied by Sir William Dawson ^ and Penhallow.* A com- 

 bined list of their determinations is as follows : 



Cupressinoxylon sp., Dawson 



Cycadeocarpus (Dioonites) columbianus Dawson 



Ginkgo pusilla Dawson 



Neuropteris heterophylla Brongniart 



Nilsonia polymorpha cretacea Penhallow 



Osmundites sTcidegatensis Penhallow 



Sagenopteris elliptica Fontaine 



Sagenopteris Nils07iiana (Brong.) Ward 



Sagenopteris oblongifolia Penhallow 



Sequoia Langsdorfii (Brongn.) Heer 



Twniopteris plumosa Dawson 



Taxoxylon sp., Dawson 



Zamites crassinervis Fontaine 



Zamites tenuinervis Fontaine 



The bulk of the foregoing names are obviously incorrect identifications, 

 e. g., Neuropteris heterophylla is a typical carboniferous Pteridosperm, 

 one of the Sagenopteris species is Jurassic and the Nilsonia is Ehsetic, 

 while the Sequoia is Tertiary. 



BRITISH COLUMBIA 



What is probably the northward extension of the Shasta-Chico series 

 outcrops at various localities in British Columbia and probably in the 

 Yukon territory, but the areas are so remote and scattered that the details 

 of the geology and the fossil floras have only been worked out in a pre- 

 liminary manner.
