in a game when the barbarians appear, they repelace one of the other civs in the list.
if the barbarians are the 8th civ then you are the 9th - it doesnt matter who is the 8th the fact is thre are a total of 9 civs including yourself and the barbarians, and only 8 are to be displayed on a screen at a time.
e.g. i had a game with australia, niguragua, france, mongols, greeks, jamacians, english, myself and the barbarians. the F3 key only lists: myself, australia, niguragua, france, greeks, jamacians, english, and barbaians. it leaves out the mongols. hence it shows 8 civs including myself and the barbarians and drops an AI civ - the mongols.
{edit}
see for yourself i put the mogrols in the background, but you will not see them in the list.
