Exotic charmonium-like spectroscopy at LHCb: a study of the X(3872) and   of the Z(4430)^-
  I will report on the recent LHCb results on the evidence for the decay $X(3872)\rightarrow\psi(2S) \gamma$, and on the improved measurement of the mass and width of the $Z(4430)^-$, the determination of its quantum numbers and the observation of its resonant character.
