The fairies of Wales may be divided into five classes, if analogy be not too sharply insisted on. Thus we have, 1. The Ellyllon, or elves; 2. The Coblynau, or mine fairies; 3. The Bwbachod, or household fairies; 4. The Gwragedd Annwn, or fairies of the lakes and streams; and 5. The Gwyllion, or mountain fairies.
