The paper adjoins the book of B. I. Plotkin and S. M. Vovsi Varieties of Representations of Groups (Zinatne, Riga (1983)) and turns to be, in a sense, its continuation. In the book, the varieties of representations have been considered. As a matter of fact, the varieties under consideration are action-type varieties. This paper studies other classes of representations, axiomatizable in a special action-type logic.
