From The Lesser Key of Solomon, Crowley/Mathers edition:
The Sixty-ninth Spirit is Decarbia. He appeareth in the Form of a Star in a Pentacle, at first, but after, at the command of the Exorcist, he putteth on the Image of a Man. His Office is to discover the Virtues of Birds and Precious Stones, and to make the Similitude of all kinds of Birds to fly before the Exorcist, siging and drinking as natural Birds do. He governeth 30 Legions of Spirits, being himself a Great Marquis. And this is his Seal, which is to be worn, etc.
