Opus- Had a look into it but can't find anything spiecific at present,try again tomorrow. Is it the best example you have come across i'm sure there are others, and anyway can you not argue that it is just a later redaction of the original text to identify the the area/city. I am certain that is is the case of the translators of the LXX, they are following Herodetus, and others pre 300BCE, there some refs to that.
