Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
Amduscias governs twenty-nine legions. His true form is as a unicorn, but appears as human form when summoned. He will give concerts if commanded, & is accompanied by the sound of trumpets and other musical instruments. Trees also bend to his command.

The Sixty-seventh Spirit is Amdusias, or Amdukias. He is a Duke Great and Strong, appearing at first like a Unicorn, but at the request of the Exorcist he standeth before him in Human Shape, causing Trumpets, and all manner of Musical Instruments to be heard, but not soon or immediately. Also he can cause Trees to bend and incline according to the Exorcist’s Will. He giveth Excellent Familiars. He governeth 29 Legions of Spirits. And his Seal is this, etc.
