Oh but 'list' is so prosaic. I like "bestiary." It recalls fables and legends. It comes out of the Middle ages. It suits the fairie realm.
EDIT: My point about the beastial conundrum was to suggest that the old line drawn between humans and beasts or animals is not tenable in Middle earth. Nor, in fact, has it always been observed in our primary world. But that is a different argument.
