This is a seal from the book "Lesser Key of Solomon". According this text, the spirit Amon , is described thus
"The Seventh Spirit is Amon. He is a
Marquis great in power, and most stern. He appeareth
like a Wolf with a Serpent’s tail, vomiting out of his
mouth flames of fire ; but at the command of the Magician
he putteth on the shape of a Man with Dog’s teeth beset
in a head like a Raven ; or else like a Man with a Raven’s
head (simply). He telleth all things Past and to Come.
He procureth feuds and reconcileth controversies between
friends. He governeth 40 Legions of Spirits. His
Seal is this which is to be worn as aforesaid, etc."
