NOTE. 



It should have been stated on page 81 that the Levis formation is now divided, the 

 upper portion having been set apart under the designation of the Lauzon formation. 



The three species of fossils referred to the Sillery occur in the upper part of the 

 Lauzon, near the base of the Sillery. 



In the fifth line from the top of page 81, for 3 read 5.
