This is a seal from the book "Lesser Key of Solomon". According this text, the spirit Malphas, is described thus
"The Thirty-ninth Spirit is Malphas.
He appeareth at first like a Crow, but after he will put
on Human Shape at the request of the Exorcist, and
speak with a hoarse Voice. He is a Mighty President
and Powerful. He can build Houses and High Towers,
and can bring to thy Knowledge Enemies’ Desires and
Thoughts, and that which they have done. He giveth
Good Familiars. If thou makest a Sacrifice unto him he
will receive it kindly and willingly, but he will deceive
him that doth it. He governeth 40 Legions of Spirits,
and his Seal is this, etc"
