I have begun reading the first of the Flash Gordon daily comic strips, and as I progress, I shall be adding to the Lists of Mongo as new subjects make their first appearance (such as the porcon, the horrosaur, and the cat-horse, all of which first appear in the dailies of May 1940).
Thinking about how I wish to organize the lists with the addition of material from another (albeit parallel) source, I originally planned to keep the Sundays and dailies in two separate lists, but I decided it would be easier for everyone if I integrated them and simply added (D) to those subjects that originated in the dailies. This prevents duplication and enables me to easily check chronology.
