After Neptune was discovered, they were claims that its orbit didn't seem to be as predicted. This led to the conclusion that it must be disturbed by another massive planet beyond it.
Later Pluto was discovered, but it's mass was not large enough to disturb Neptune. For many years astronomers searched for another planet, but it was recently discovered that Neptune's orbit is not as perturbed as once thought, so the "need" for another planet is gone.
