3. The Lower Shales, or Subdivision C, 



The Lower Shales are remarkable not only for the occurrence in 

 them of anthracite coal and clay ironstone, but also for the abundance 

 and great variety of the fossils which they contain. As the fossils 

 collected by Dr. Dawson are not all from precisely the same geological 

 horizon in these shales, it will be desirable to give a list of the species 

 from each locality before discussing the probable age of the series as a 

 whole. 



A. — From Cumshewa Inlet. 



No. 1. " Fossils from the Peninsula, north shore of Cumshewa Inlet 

 and at dift'erent places a few miles west of the Peninsula. All from

 division C of the Skidegate section." (Dr. G. M. Dawson.)
