Notes

George Hanson, Director, Geological Survey of Canada writes in the Preface "... This memoir summarizes particularly the results of the study of the sediments adjoining the contact between the latest Mesozoic and earliest Tertiary formations together with a detailed description of their known freshwater and terrestrial molluscan species. A correlation table and a series of sections showing the positions of the fossil beds are presented, also nine plates containing one hundred and thirty figures illustrating species of the molluscan fauna and six tables listing their distribution in the formations. An index of the exact localities from which the molluscan shells were collected is given and this and other data will be of great assistance in studying the coal measures, and preparing sections correlating the beds encountered in wells drilled through these formations for oil or gas in the underlying strata.
