Griffins an a few other mythical creatures would be too. Pegasus may or may not. The original was sired by Poseidon and itself was a god, but its since become a generic name for winged horses so that leaves room for debate.

Yes I do enjoy fiction taxonomy, why do ask?

Depends on the wings. If they're back mounted, I'm not sure they count. They don't count for insects. We don't say flies have 8 limbs.
