The (n + 1)-ary derivations of simple non-Lie n-ary Mal'tsev algebras are described in the case of the binary algebra M-7 and the ternary algebra M-8. As a consequence, a description is obtained for the 3-ary derivations of simple non-Lie Mal'tsev algebras and simple finite-dimensional non-Lie binary-Lie algebras. Examples of semisimple Mal'tsev algebras having nontrivial 3-ary derivations are given.
