There seems to be some confusion about Aim (aka Aym, Haborym) in demonology texts. Gustav Davidson (1994) identifies Haborym as Raum [ref]Davidson, Gustav. “Haborym.” A Dictionary of Angels: Including the Fallen Angels. N.p.: Simon & Schuster, 1994. 131. Print.[/ref]
, and Collin de Plancy (1863) mentions that some do identify him as Raum, though he (de Plancy) doubts the two are the same.
Aym / Haborim in the Pseudomonarchia Daemonum
Weir (1583) describes Aym as a Great Duke who commands twenty-six legions. He appears with three heads (a serpent, a man with two stars, and a cat). He rides a viper and carries a torch that can set castles and cities aflame. He makes people witty and answers truthfully concerning private matters.
Aym or Haborim is a great duke and a strong, he commeth foorth with three heads, the first like a serpent, the second like a man having two stars, the third like a cat, he rideth on a viper, carrieng in his hand a light fier brand, with the flame whereof castels and cities are fiered, he maketh one wittie everie kind of waie, he answereth truelie of privie matters, and reigneth over twentie six legions.

Haborym in the Dictionaire Infernal
According to Collin de Plancy (1863), Haborym, also called Aym, is a fire demon and a duke of hell who commands 26 legions. He appears riding a viper, holding a torch and has three heads (a serpent, a man, and a cat). [ref]Collin De Plancy, Jacques Auguste Simon. “Haborym.” Dictionaire Infernal.

Aim in the Goetia
Mathers (1904) deviates slightly from de Plancy and Weir’s description of Aim, in that he says his third head is like a calf, rather than a cat.
The Twenty-third Spirit is Aim. He is a Great Strong Duke. He appeareth in the form of a very handsome Man in body, but with three Heads; the first, like a Serpent, the second like a Man having two Stars on his Forehead, the third like a Calf. He rideth on a Viper, carrying a Firebrand in his Hand, wherewith he setteth cities, castles, and great Places, on fire. He maketh thee witty in all manner of ways, and giveth true answers unto private matters. He governeth 26 Legions of Inferior Spirits; and his Seal is this, which wear thou as aforesaid, etc. [ref]Mathers, S. L. MacGregor, Aleister Crowley, and Hymenaeus Beta.
