Constructional names and symbols for all 32 of the subclasses of meteorites recognized in the simplified classification are given. These names and symbols indicate, in each case, the general structure and mineral composition of the comprized meteorites. The paper contains 4 tables: (1) 20 qualifying symbols or qualifiers; (2) symbols for the 16 minerals commonly occurring in meteorites; (3) symbols for 24 other minerals found in meteorites; and (4) the 32 subclasses of meteorites and their symbols. Some 13 subclasses that have been excluded from the simplified classification, and both “composite” and “transitional” meteorites are condensedly discussed. Finally, the classificational sequence of meteorites, which is a sequence primarily of increasing density from left to right, is written out, in terms of the new constructional symbols, for all 32 of the subclasses in the simplified classification, and the sequence is briefly reviewed.
