In this paper1 we complete the results of  and consider the problem of the determination of the conjunction and the disjunction of two axioms. We apply the results obtained to the search of equational bases for all the subvarieties of the class DMS of double MS-algebras. Finally, we determine all the subvarieties which can be characterised by exactly one of the 60 axioms which were considered in .
