I am sorry to say that only the four "Galilean" moons Io, Europa, Ganymeade and Callisto are generally visible through amateur equipment.
Most likely your extra moon is a field star--Jupiter is very close to two tonight, one Magnitude 6 and the other Magnitude 8. Either one could be right in the same field as your moons tonight.
Sky and Telescope's Web site has a neat java calculator that will show you which moon is where at any given time:

Alas, it was with great disappointment that I learned the fifth moon was actually a field star. Jupiter's fifth-brightest moon is not visible in any low-power binocular, even the gigantic 25x100mm variety. It was a nice illusion while it lasted though...
Don't even ask me about the time I saw a Kuiper Belt object in my 25x100 binoculars.........
Clear dark skies...

There is alot to learn in this "hobby" I'm sure I'll appear to be "addlebrained" again in the future. Thanks for letting me down gently.
I do enjoy ALL the opinions and information. It's good to see "grown" men and women so enthusiastic about an academic(of sorts) hobby, rather than just sitting and staring at mostly BAD television.
