  We will revise Garnier-Okamoto's coalescent diagram of isomonodromic
deformations and give a complete coalescent diagram. In our viewpoint, we have
ten types of isomonodromic deformations and two of them give the same type of
the Painlev\'e equation. We can naturally put the thirty-fourth Painleve
equation in our diagram, which corresponds to the Flaschka-Newell form of the
second Painlev\'e equation.
