This volume is intended as a companion to Memoir 83. Primarily, it is a study of fossils collected by the writer in southern Ontario, and Quebec, during the summer months of 1911 and 1912, but it describes also the other species known to exist in these areas. [...] Collections were made by the writer, in southern Ontario and Quebec, chiefly from strata corresponding in age to the Richmond formation of the Ohio-Indiana-Kentucky area.
