Since a Majorana neutrino is its own antiparticle under CPT, rather than C, an analysis of the CPT and CP characteristics of a Majorana particle is performed. The CPT transformation properties of a Majorana particle of arbitrary spin are obtained in a very simple way. Implications of these properties for the electromagnetic matrix elements of Majorana particles of spin (1/2) are derived. Finally, the question of when different Majorana neutrinos will make opposing contributions to neutrinoless double-..beta.. decay is answered.
