The distributions of 141 globular clusters in the Galaxy and 54 globular clusters in the LMC in space with coordinates being their dynamical parameters are considered by taxonomical analysis. The majority of clusters are shown to enter several taxons (classes) with narrow enough limits of these parameters. Classes are not isolated and continually transfer between each other. It possibly means an absence of significant gaps in clusters' formation process. Taxonomical analysis of the joint distribution for both samples showed that though LMC clusters essentially differ in color and mass in the space of their dynamical parameters some part of them are similar to Galaxy globular clusters.
