Extinction vs accuracy

[Heath, Fred]

Dear Parick,
        Just for my continuing education, what does the word extirpated mean
in a biological sense? In my ignorance, I've always used extinct when a
species was totally gone worldwide and extirpated when talking about a local
population. Obviously, if a local or island population is a distinct
subspecies (however that is defined) then the subspecies could be extinct,
even though the species is still viable elsewhere.
---Thanks, Fred
