 Unfortunately, his own favorite examples, “elm” borrowed from Putnam (1975) and “frog” are not terms for species. “Elm” is a genus and “frog” an order. In fact, a quick consultation with a good dictionary will reveal that most commonly used biological terms are expressions for some classification above the level of species. Since Wiggins is cautious about extending his account to genera, he may have very few substance sortals by his account.
