In Missis Defunctorum non dicitur miserére nobis, sed eius loco dona eis requiem, et in tertio additur sempitérnam.
This rubric governs Masses for the Dead: there “dona eis réquiem” takes the place of “miserére nobis”, and the third time “dona eis réquiem sempitérnam”. At those Masses the priest does not strike his breast, and the kiss of peace is not given.
