Hi Kay,
As Maarten says under the title it does say that this is some of the list of French-speaking countries and not the full list.
If you are interested in knowing more, you will find the info on the following website -
https://www.francophonie.org/88-etats-et-gouvernements-125
Incidentally, Tahiti is an island which is part of French Polynesia.
Bonne Continuation!
