Eighteen Yamato basaltic achondrites have been examined and preliminary descriptions are given. They include eucrites, polymict eucrites, howardites and a new group of pyroxene-rich meteorites here described as pigeonite cumulate eucrites. Most of these meteorites are similar to previously known basaltic achondrites. The pigeonite cumulate eucrites contain more feldspar and glass than the diogenites and more pigeonitic pyroxene than the previously known pyroxene-rich cumulate Binda. They may be similar to the pyroxene-rich Y-75032. The achondrites studied sample almost all the types of basaltic achondrites known and deserve further study to constrain models of parent body genesis.
